November 15th 2018 – Shooting with Models

A practical in three parts using local models Ashley Claire, Steph Kiddle and Paul Walker, who were brilliant (as usual) and four lighting stations (the fourth being occupied by a mannequin’s head) run by club members, Richard Clayton, Steve Dyer, Gerry Painter and Myk Garton.

Again, I am glad to report, there was much discussion and sharing of knowledge and practice between members and it just underlines the wide range of experience there is in the club and a shared willingness to develop as photographers together.

Using lights/flash/combination thereof we can, as was amply illustrated, create a wide range of lighting effects. All are about the light, of course and when we say light we also mean shadow. In fact without at least a hint of shadow we aren’t going to have an image. There has to be a minimum of contrast.

There are two sorts of contrast, colour and tonal. Colour contrast (a.k.a. luminance or luminance contrast) is the difference in the colour and brightness of the object and other objects within the same field of view (or frame). Tonal contrast is created when light tones and dark tones lie alongside each other.

This weeks blog is going to concentrate on tonal contrast, easiest when referring to monochrome, more specifically black and white (there are other colour combinations, for example cyanotypes). Luckily there was a station using Film Noir as its inspiration, run by Richard.

Although the noir refers to the darkness at the heart of the story line, hard contrast lighting was, in turn, at the heart of its cinema photography especially in its mood setting scenes.

Although this can be accessed using natural light, by far the best technique is to choose the background first and then place the subject in it. That applies to nearly all photographs, one way or another, but, given the inflexibility of natural daylight at any given time, it is a pretty sound rule of thumb.

And keep it simple.

But we were talking about studio (at least indoor) photography, being by far the easiest for the amateur photographer to control. It is quite straight forward but takes application to master. Like any other skill it needs to be practised.

The nature of our cameras’ sensors is that, at least at the current time, they can “see” a lesser range of dark to light than can our eyes. This means that certain decisions have to be made and introduces us to a rule of thumb known as “Exposing to the right” or ETTR. It applies to monochrome and full colour. It’s also a strategy known as “Protecting the highlights”.

The right referred to is the right hand of an exposure histogram. Most CSC/DSLR cameras produce one of these for each shot. The right hand side plots the brightest part of the picture. If not accounted for – if the end of the graph shows a big spike – then areas of our image will be burnt out – just white with no detail.

Generally we try and avoid this by exposing for these highlights. Shadows also hold a lot of detail and it is easier to get this back into the final image than detail in the highlights. We want to try and avoid a spike (the spike is evidence of something called “Clipping”) to the left too, where everything is too dark to see detail, but, normally, shadows are more forgiving.

The reason that black and white is a good way to do this is that it takes the distractions of colour out of our equation. The results are a little more obvious and black and white has an aesthetic all of its own, particularly boosting the effect of shape and line.

Metering in general tends to be something that first timers, in particular, can find a little difficult. Yes we can buy flash meters, but they are not cheap. They do make things go a little quicker. However, good old fashioned practice will soon determine what is right using test shots.

The guide number for our flash gun is the how far that unit will project light at theoretical f1.0. This will be a GN xx and is usually printed on the unit or it can be found in the handbook. It is calculated thus: Distance x Aperture = Guide Number. So my Amazon Basics flash unit has a GN of 33 (Meters) on full power. So if I want to use an aperture of f8 my optimum distance to set the flash is 4.125 meters (13 feet 6 inches) calculated GN/Aperture=Distance or 33/8=4.125.

In reality I would probably set the unit to ¼ power and put the flash between 3 and 4 foot way. It would be a start because ambient light will play a part and whether the flash gun is the soul light source (rare for me) or balancing out ambient light. Again practice is the key and this is one instance where chimping is a desirable technique. Trial and error is a good teacher.

Thus far thus technical. But, and when shooting models it is a big one, by far the most important thing it is talking to not at or down to our model. If they are experienced they probably know a lot more about this process than we do.

Lighting the Portrait – by Richard Clayton.

How many lights does it take to successfully light a portrait, two, three, five? In reality, it only takes one light to make a successful portrait – and the best way to start, is to learn with one light. Look at the shadows it creates, lighting a portrait is as much about shadows as it is about highlights.

Add a modifier and see how that affects the quality of the light.

So what light should we use? The answer is any light will do, from a desk lamp all the way to an expensive pro level strobe, but don’t forget that abundance of free light that comes through a window.

Whatever light source we use, we can modify it in much the same way.  A soft box for a strobe or some heavy net curtain for a window. Why not a soft box for a window? Well, one of the jobs of a soft box is to make a small light source bigger, with a window, we already have a large light, we just might want to diffuse it a little.

If outside, and wanting to use the free light in the sky, AKA the Sun, our best bet is to find some open shade, this will act like a large soft box in the fact that the light will be softer and less contrasty, we won’t get uneven highlights and shadows on the skin.

There are many options for a single light source that will make a great portrait. Mastering one light, gives us more confidence to add another. Recreate this video, it doesn’t matter what light source, and black and white is as good as colour.

22nd, 29th March – Peter Weaver and a Practical Evening

Apologies for missing a post, IT problems. Our guest speaker was the always welcome Peter Weaver, who will be returning in a couple of weeks to judge Round 3 of the Open Competition. This was followed by a video tutorial and a table top session. Peter showed us many instances of his own photographic journey and this set me to thinking about one particular aspect which we have talked around but not directly addressed in a while, that of taking pictures of people.

There are many forms this can take from the happy snap via passport style documentary through street to high art. For all of these we are going to use the same basic formula with appropriate, or lack of appropriate, vigour, starting with the background, putting our subject in it, lighting it then recording it. We are speaking generally.

So, background. Avoiding the classic lamp post/tree branch growing out of the subject’s head takes a bit of practice. Border patrol needs to become a habit when our attention is mainly on the subject, but that is easier said than done, especially when we are starting out. Choosing the background against which we will contrast our subject helps in getting this right. Not fool proof, but it works more often than it doesn’t and that little equation can be affected positively by establishing a routine and sticking to it.

Two easy to stick to rules for backgrounds are fill the frame with your subject (goes for all single subject photographs) and blur the rest. In the first of these we can either zoom with the lens or zoom with our feet. Perspective doesn’t change the same way when we zoom with the lens as when we zoom with our feet, as different focal lengths will handle background compression in a different way (sort of, it’s the subject to distance that changes in order to keep the subject the same size in the lens).

Putting the subject into a pre-selected background minimises the chances of there being unintended distractions in frame. Basically, if it doesn’t add to the story you are trying to convey, get rid, either by moving to another location, cropping tighter or changing the angle between lens and subject.

In the studio we might generally light the scene at this stage and refine with the model in it, which is fine where control is total, but we don’t always have this option. In more public and more chaotic situations, “Running and Gunning”, we might need to see what we are lighting first but this is really a personal preference and down to the workflow we adopt – not all workflows are automatically the most efficient but we are after the most effective and that means thinking critically about them from time to time.

Where ambient light is variable it is preferable to put the model in the scene, then light. Variation is part of every point on this process as each time something changes we have a different image and opportunity. Being prepared for the opportunity is a vital step in capturing it.

 

Posing our model is relative to the formality of the shoot.  The corporate head shot is probably the most convention bound of these as portraits of friends informal. Inflation of ego aside, it always amazes me that the item by which their audience is going to judge them most, the  corporate mug shot on the annual report, on advertising, on the web, commands such little time in the executive’s “busy” day. Herd instinct aside, the corporate headshot is a very conservative market. Everything can be pre-lit because so very little changes.

Admittedly there are poses to generally avoid because body language is very  specific in what it conveys. Posing is also gender specific, at least by convention, so we have the idea of male poses and female poses, which, in actuality, are merely what society expects.

Then the lighting. Lighting is as straight forward or as difficult as you want to make it. Essentially it is the interplay of light and shadow and it is something over which we have varying control over depending on the environment we are shooting in.

A home photo-studio doesn’t have to be expensive to build, and if we start out with flash, as many of us do, then we have a very versatile and portable light source that has many uses, the light from which can be usefully and quite cheaply modified for hard light (grids, snoots, beauty dishes and reflectors) or soft (soft boxes, umbrellas, diffusers and flags). What we get in the studio is control.

Light is by far the biggest factor in any photograph. It’s in the name, as we have discussed before. Its qualities are exactly what we trade in. That balance of light and dark we control has four elements: quality, position, intensity and colour and the modifiers are how we go about it when using artificial lighting or a mix. The portability of modifiers (well the smaller ones, a seven foot octobox may not weigh a lot but the slightest of breezes will turn it into a sail) doesn’t preclude them being used outside (and here).

As, more often than not, we are using a mixture of ambient and boosted light, the options for control are broad. For non-artificial lighting we have the exposure triangle, white balance and filters to affect the look of the light. We have exposure compensation, full manual too.

It is all dependent on the way things are arranged in the frame of course. Composition is no small matter. It is as important as the light, indeed it is at least half of what we do to capture our vision, that thing that grabbed our attention.  It’s about  making a statement, or taking that statement and making it our own, but remember : “It’s one thing to make a picture of what a person looks like, it’s another thing to make a portrait of who they are.”

8th March 2018 – Gerry Painter playing with light and dark

Our thanks to Gerry Painter for a very informative evening, using his photography to show how to play light and dark using a basic home studio. Gerry showed us how to get great results using a sound grasp of how light and flash work, and the basics of posing your subjects for effect.

And it doesn’t have to demand a big budget. There are hacks you can take in order to get the look you want without, necessarily, spending a fortune. You certainly don’t need a full-time studio so you can use flash for portraiture, but a studio does present the peak of the idea of a controlled photographic space. We have touched on this before this season with club member Steve Dyer when we talked about a basic off camera flash set up, and I would suggest that post is worth a re-read from the point of view of building the hardware side. It also links back to two earlier posts, one covering hard and one covering soft light modifiers.

Photographing people is, quite possibly the major part of photography. Certainly, it makes up a large, perhaps the largest, sector of the professional market. What people are paying for is not, necessarily, a straightforward record, but a record of a connection, one that brings out their personality, a fraction of a life, something which speaks of them and of the moment. Even though we live in the age of the selfie there is still a perception that there is something else to be had from the viewpoint of another.

Even so, the motivations behind the selfie, which love it or loathe it are massively the largest by number photographs posted online, 24 billion 2016 according to Google, are not so simple. The motivations for those so bent on broadcasting their lives to the point of dying of it, more people were killed taking selfies than in shark attacks that year, are not just narcissistic.

Within this huge volume, the data for Instagram alone, and what can be derived from it, is far from trivial, there are, apparently, three categories of motivations : Communication – those who want to inititiate conversation; Autobiography – those who are recording key moments in their lives, not necessarily to bait a response, but as a record they can look back on in a handy format; and the smallest of the groups, the Self publicists – those with a personal or professional need to be “out there” and recognised. “It’s a different kind of photography than we’ve ever experienced before” (Steven Holiday, Brigham Young University) important because it is today’s social history for the future. It can also prove expensive, in more ways than one.

Even so, the basic human form hasn’t changed and that means there are more natural and flattering angles than others, and Gerry took us through some of the basics. First off there is not taking pictures square on, something you can sometimes get away with on male subjects, but almost never seem to work with female ones. And there is a big difference to be had through the simple expedient of shifting the by slightly putting one leg slightly forward, shifting your model’s weight and causing an S-curve. Shifting the weight onto the back leg Leaning forward from the waist and raising the chin smoothes lines around the neck and invites the viewer into the picture. For effect this doesn’t have to be exaggerated, indeed it can look slightly comical if it makes the model look overbalanced. This works for male and female models. As does crossing the arms, which with the other moves described, makes the body look more dynamic.

If the model is sitting then the relative height differences are going to become exaggerated and the crops tend to be much tighter. The leaning forward posture still applies otherwise the model looks like they are backing away. Elbows on knees will tilt someone forward and an accompanying tilt of the head makes things much more personable. In all cases, the eyes are the most important point of focus. If there is one other thing that is universal is the general advice that it is better to have the model angle one shoulder towards the camera.

Gerry packed a lot into one evening not least the need for a connection between the model and the photographer, especially with a model who might not be used to having his/her photograph taken. A lot of people don’t like having their photograph taken. A lot of people buy a camera to make sure they are the comfortable side of the lens. Our job is to put them at their ease. This can be easier said than done and the reasons are pretty hard-wired because the thing we as photographers are looking for is the thing we as individuals do not want to give away.

Experience in other fields leads me to believe that the single biggest factor is the attitude of the photographer towards the person being photographed. Put simply, the attitude you give dictates the attitude you get back. If you are wound up and edgy guess what your model is going to pick up on? Give out a “This is going to be a nightmare” and you get a self-fulfilling prophecy. It’s as much to do with what we do before we start shooting as it is during the shoot. It’s about time spent introducing ourselves and what we have in store for our subject. It’s about promoting the shoot as a joint project either side of the lens. It’s about making being the model on a photo-shoot as something enjoyable. You only have to get part of the way to free things up.


 

On a slightly different note, regular club members will know that Myk Garton last year had a successful exhibition called AS I SEE IT at the Totterdown Canteen (141 Wells Rd Totterdown Bristol BS4 2BU). Myk has got the club a return gig which will be called AS WE SEE IT and photographers within the club have opted to show in the exhibition which will be in May June this year. This is a great opportunity to get and see the club in action. Opening times are 8 a.m. till 3 p.m. seven days a week, More on it as we get closer to the date.

4th January 2018 – Thinking small practising for big.

Happy New Year and we celebrated our return with a well attended evening of table top photography – next week we show the results. This is a good entry point to the year, it’s practical so we get to see and do with others and exchange ideas, but also it is something that we can exercise (more or less) total control over. Yes it might not be our “thing”, yes in the hall we are at the mercy of the overhead lighting and others waiting their turn (on occasion) but the opportunity is the thing.

 

The fact is we can, with very little resource, replicate these moments and use them to our advantage. Find an object – betting the house is full of them. It doesn’t matter what particularly, but, to start with, one that isn’t too shiny, so as we avoid bright spots (specularity) where light sources are reflected in the objects surfaces and not too big – it’s called table top for a reason. This can be controlled but we will come back to that presently.

 

For lights we have torches, they don’t have to be big and powerful (actually something of a disadvantage at close quarters). Some wire twists and something that will be stable when we attach the torch(es) to it as a light stand (or co-opt a friend or relative). Some plain paper to use as a diffuser and Christmas having just passed some coloured sweet wrappers for gels. If we want we can construct yourself a makeshift light box out of an old cardboard box and some grease proof paper, though there are even more minimalist options we can take. We can use tin foil and black card for reflectors and flags.   Ladies and gentlemen I give you your complete photographic studio in miniature!

 

So it’s an entertaining way to pass an evening, useful if we are selling small things on line and we can learn quite a bit about product shots in the process. But it also has other, practical, training uses. It doesn’t make a difference how experienced we are there is always a value to practicing, especially if it is on a subject we don’t usually do. Photography, as David Bailey once pointed out, involves dealing with what is there, photographers don’t enjoy the luxury fine artists have in that anything inconvenient in the scene just doesn’t make it onto the canvas.

 

We have to deal with what is in front of us. The studio is the closest we will ever get to that situation, in miniature or otherwise, being places we put things in rather than take things out. Being a photographer is about having an idea of an image and working with tools we have or can find to work towards what we visualised. Yes I know, that doesn’t really apply to street (actually is does but that is for another time) or at least some forms of street photography. Oh, OK, spray and pray, but like I said, that is for another time.

 

Perhaps the greatest part of this is that we can go through the whole process from visualisation to capturing an image effectively and quickly. And then we can go through the variations of the set up in order to experiment and learn.  Starting with a blank canvas, the light tent is exactly that, we can populate, arrange and light our little stories from scratch. It is a great way to practice basic lighting skills, pretty much for free. In fact thinking of the exercise of placing shapes in relation to each other in a way that gets the attention and lighting it is pretty much the basic definition of photography. Everything we do in these little vignettes can be scaled up. They are good fun and good practise.

 

There is more good practice to be had in controlling light angles too. We mentioned specularity above, basically unwanted reflections. The solutions are straight forward enough and apply to other photographic situations too. Basic rule of reflections is that the angle of incidence equals the angle of reflection. What that means for us is that to avoid glare from a shiny object we don’t need the light source and the camera to be facing the same way. Frame with the camera and then move the light around till the glare disappears. Start at 45 degrees to the camera, you should be plumb in what is known as the family of angles.

 

Constant lights are more convenient here but if we use flash and have triggers so we can use them off camera and using test frames and, of course, knowing the rule of reflection, we know where not to place the lighting in relation to the camera, so that is a start. You don’t necessarily have to have triggers though. The  rest of the solution isn’t complicated and if we use a “big” light source, say from a large soft box then the problem goes away. Don’t have a soft box? A light tent is one answer (basically a multidirectional diffuser). No? A piece of white card to use as a reflector, shoot with the camera facing the card, that will effectively diffuse the light.

 

Finally shadows are just as interesting, if not more so on occasion, and balancing out light and shadow is the root of generating mood in a shot. This is done with what are known as flags. They are used a lot in cinematography and videography. They are also used in product photography. Using them in a table top situation means that DIY options are easily available.

 

So, on these cold and dark evenings there is something to try out.

19th October 2017 – Mike Martin, Making Art Your Own Way

Mike Martin, a member of Kingswood Photographic Society, and a fine photographer, was our speaker. Happy to be a photographer who shoots with post production in mind and only himself to please, Mike showed us a strong, varied and interesting set of mainly art images, with some interesting detours into other genres.

 

He never accepts images as they come out of the camera, viewing this as a stop on the way to what he imagined in the first instance. This can mean a long time in post production, but as an unashamed amateur – i.e. he’s not shooting to a deadline and other people’s  tastes – this is a luxury he can afford. This is part of a long art photography tradition and now that we have the tools to do things in seconds what it would have taken hours and much coin to achieve – if it could be done at all – for an absolute fraction of the cost.

 

Although there is much to be said for getting as much right in camera, that is an awful lot easier when starting with the end in mind, in having a strong idea of what the finished product will look like. This may change as you go along but having a defined end usually leads to less time wasting. Not always, but usually.

 

This is not to say that we shouldn’t experiment or take on new ways of doing adjustments. There is a balance and if we want to learn then making ourselves a little bit uncomfortable by trying new things is going to be an essential part.  Looking, emulating, developing, employing is as good a learning cycle as any.

 

Mike also quoted Henri Cartier Bresson, which we have discussed before: “Sharpness is a bourgeois concept” – that is one that makes the holder appear self important and materialistic, shallow, pretending to be deep, unsophisticated and generally lacking in true class. Certainly it has its place – sharpness is one thing that sells new and ever increasingly expensive lenses. Yes you could back a modern lens against the ones that HCB used pretty much every time in the sharpness stakes, but it’s the brain behind the camera that makes a difference. Mind you context is everything:

“He had his little Leica,” Newton remembers, “and he simply would point and shoot.” Since Cartier-Bresson’s hand isn’t as steady as it used to be, some of the pictures were a bit fuzzy. “Sharpness,” he told Newton, “is a bourgeois concept.” Newton sits back and laughs: “I thought that was just divine.”

Dana Thomas interviewing Helmut Newton, Newsweek, 1 June 2003.

 

Movement certainly formed part of HBC’s photography, two of his most famous images in particular (“Man jumping over a ladder” and “A man rides his bicycle through the Var department”) and blur is certainly going to feature in that – as opposed to the shaky hand of the nonagenarian, as Newton observed.

 

So shaky hand blur and motion blur might be two different things. One will happen at some point in an otherwise unsupported situation as shutter speed, that is the length of time the shutter is open, comes down. Lens/sensor stabilisation certainly lowers the point to where such shake becomes evident and it can even be used as a creative effect by giving us time to move the camera around a fixed point or through a plane.

 

The motion blur we are probably most aware of is the one created by panning with a slow(ish) shutter speed. This keeps our main subject in focus and acceptably sharp  but blurs the background. We often see this used in motorsport photography  and it is also known as a tracking shot. The flip, of course can also be used, where we use a slow shutter speed with a fixed camera and our subject moves across the frame. So we can freeze or blur our subject to get a different feel of motion. The key to both is shutter speed. It can be achieved with a single strobe, or with mixed lighting, the key to both is synchronising the flash with the second curtain also known as the rear curtain. Essentially this means firing the flash at the beginning or the end of the exposure. The effects are very different

 

There is another way of using motion blur that you can use with a zoom lens. It’s called, wait for it, zoom blur. Again it really requires a tripod or at least a monopod because we are working with slow shutter speeds, but the mode, shutter, aperture, manual is less relevant. All these effects are relatively easy to use, but, as with everything else, need a little practice to get right. Even then, especially with unpredictable subjects, it is best to plan a series of shots to give you one or two to work with in post – assuming you need to. That said, motion blur is rewarding to play around with the effects and can also be used in the dark!

 

So an interesting evening that showed many possibilities, the value of forward planning and an artistic vision and not just by adding things in post, but in taking distractions out too. An interesting, varied and singular evening. Our thanks to you, Mike Martin.

12th October 2017 – Steve Dyer My Photography & Building An Off Camera Flash Set Up

This week we had our first of the season’s My Photography sessions, Steve Dyer taking us through his studio work including lights, modifiers and some of his post-production work flow. Some fine images, and a sound outline of the equipment he uses to get his preferred evening was an illustration of some of the talent we have in the club. And Steve was happy to state that the club has played, and continues to do so, a strong part in his development as a photographer.

 

We have looked at light modifiers in the last two posts of 2016, dividing them into soft light modifiers and hard light modifiers. We also referenced the excellent The Strobist website and it remains well worth the effort. These three will form the underpinning of the rest of this post, which will mainly, but not exclusively, be about building an off camera flash on a budget.

 

Steve has spent the last few years and not a little income in collecting his equipment he uses in his set up. The modifiers can be gained quite cheaply, but the build quality is what you really pay for when you buy the more established branded modifiers. One of the keys here is how core these pieces of equipment are to our particular form of photography. Another is our available budget, of course. It can be done relatively cheaply and here we will be looking at the options from a restricted budget perspective.

 

So, our mission is to put together a useable off camera flash with modifiers. Keeping within the basic theme we will start with the flash unit.  Canon Speedlites start at around £160 and, obviously, are designed to work with Canon cameras (though will work with other makes but might have limited use of extended features) and we can pay over £500 for the top of the range and into four figures for the specialist designs. Nikon is not so very different. But how low can we go? The main thing that we give up on a restricted budget is power, as expressed by the Guide Number.

 

The Guide Number (GN) is far more than this though. Usually expressed in meters (feet in the USA) the GN is a tool for calculating the light falling on the subject from that unit at a given distance or F-Stop. How does that work? Actually quite simple. I have a flash gun with a GN of 33. I am 2 meters away from my model. The GN = f Number x Distance. The industry standard is 100 ISO but check the flash-gun’s handbook.

So, back to school maths, GN 33 = f number x 2meters.

Therefore 33 / 2 = f number or 16.5. Set the aperture at f16 to f18 according to the capacity of the lens diaphragm.

 

In an ideal world going to 200 ISO effectively doubles the guide number. Well it would if it weren’t for the laws of physics. There is a thing known as the inverse square law. Double the distance means

four times the light to get the same degree of illumination on a subject. So ISO 400 to get twice the light on the subject from a 100 ISO base.

 

Now TTL metering will sort all this out if the flash unit and the camera are capable of dealing with it, but that basically doubles the cost of the manual flash.  Or we could buy a flash meter (make sure it is a flash meter not just a light meter, and better it is calibrated for photography. as we may waste our money) to do accurate calculations for us. However, dedicated off camera flash meters start at around £175.00. Not within our remit here. This is one area where chimping comes in and getting to know your equipment will really pay off. We can, with practice, get pretty close to right first time but, with the cost per frame and immediacy of digital, test frames consume not a lot other than a little time.

 

As we are talking off camera flash we will need some way of triggering the flash off body. Basically there are three ways to do this: Fixed cable (if the flash unit will take that, but most modern ones will); light trigger; wireless trigger.

 

Wired isn’t much, if indeed any, cheaper at the budget end of the spectrum than wireless. Light triggers (Optical) are built into the front of flash units so enabled and are usually encased in a red plastic cover. These can be triggered by other flashed including on camera flash if you have one built in. Wireless triggers are very popular and even the cheaper ones function pretty well, though it is necessary to maintain a line of site to ensure the flash triggers. The cheaper ones will be more prone to misfire, and will have a limited number of channels they can operate over (usually 4). The more sophisticated units cost more money, are better with weaker signals, can be programmed to fire in zones or sequences, even so there are some good units out there for not a huge amount of money.

 

As an extra and when you have one, essential, piece of kit to complete this summary, a light stand is a good investment.  A light stand will take your flash to a higher angle, usually up to about 9 feet, or just under three meters. This gives us a lot more lighting options.

 

So how much can we do this for? * At 16th October 2017:

 

Flash Unit, Amazon Basics (made by Godox) £26.

Neewer Light Modifiers for Flash £46

This is a pretty complete set and a good start. Refer to the Soft and Hard Light modifier links above and note that some of these quality of light is determined by their size. This is a good place to start, but by no means the only place.

Wireless Triggers  £11

Light Stand £13.60 (two for £22 also available)

All in around £95.

Thanks Steve, for the entry point. The rest of us, enjoy.

 

*There are lights, stands and back drops that members can borrow from the club. See Eddie House.

2nd March 2017 – On lighting angles

It’s all about the light. Not sure how many times I have written that here but it is but a small fraction of the times that I have read it everywhere else.  It is also right and not quite all. It does assume that the thing you have taken the time and effort to point your camera at has a semblance of interest to someone else and that the tools of composition have been suitably employed or ignored-to-particular-effect to create something for the light to fall on, isolate, enhance and otherwise make your efforts worthy.

 

Our next session is light painting, which is always very well attended and makes the light more obvious by reducing the size, direction, angle, distance, shape and colour. These are the six things that we need to control in order to be in command of the result of the single most important element in making an image. Please making, because there is a point to be made that the camera takes the image we make. Viewed from there you can see why a little deeper understanding of light might be useful as we have identified it as the most important element.

 

OK so light without shadow is nothing and we could equally be talking about controlling shadow, in fact that is a useful starting point in itself. It is probably this fact that makes the number one accessory to buy when launching out on this path of painting with light to go with your bright and shiny new camera and lens combination is a five-in-one reflector, though there are pros and cons in using it which need to be mastered.

 

So there are a number of general rules that apply that are useful to carry around in your head, or written down in a note book – what do you mean you don’t carry a notebook? How are you going to keep a record of what works and what doesn’t; or things to try at a later date; or quick calculations of the effects of filters on shutter/aperture? – more importantly to use. So let’s use this blog to investigate the position of the light relative to the camera – just to give that notebook a nudge.

 

Think of a clock face with our camera at 6 and our subject in the centre where the hands (yes it’s analogue) meet.  The light positioned anywhere between 10 and 2 o’clock is going to produce a silhouette and a light coming from behind the subject we would normally treat as a secondary light. We always have to add a source of  light, called a fill light because it fills the shadow in,  and that can be either a reflector or a flash or a continuous light source. This fill light usually comes from anywhere between 4 and 8 on our imaginary Rolex. Creatively a light coming from behind can help create a halo that separates our subject from a dark background but we always have to be careful to light the subject sufficiently. Spot metering can help give you an accurate reading (a separate light meter also has its uses and if we intend to do a lot of studio work  or outdoor portraiture, then definitely worth putting on the equipment list, especially if working with flash).

 

When we position the light source(s) directly from the sides, 3 or 9 o’clock, we get a very dramatic effect characterised by extreme contrast. Unless there is a fill light/reflector on the other side of the subject, the camera will record the subject as being lit on one side with a dark shadow on the opposite. This can be good if you want to create a headshot with a hint of secrecy or ambiguity, less so if you want to convey glamour or a full engagement with the subject.

 

When shooting with light between 4 and 8 o’clock, I’ll come back to 6 o’clock – the camera position – in a moment, this means that the light is coming straight over your shoulders . This has a tendency to produce a flat light lacking significant shadow. Images with flat light often feel like they lack depth and never quite seem to be as we remember the scene being or intended. Basically light and shadow often require further manipulation using diffusers, scrims or in-fills.

 

The six o’clock position is where the camera is and light is at its flattest. That’s why so many on camera/inbuilt flash photographs look so unflattering. Either side of the camera, shadows are created, and shape/texture become more obvious. The width of the shadows increases as the direction of the light moves from the camera towards the side, which is why we see so many lighting set ups set between 4 and 5 o’clock or 7 and 8 – basically 45° to the camera. As a start or a go to you can’t really do better, especially if working out what is going to work best or working a number of angles.

 

And talking of angles, there are three basic ones between camera and subject, two of which are frequently ignored: that is low, eye level and high angles. By far the most photographs are taken from the eye level, which is fine but there are opportunities to mix things up a bit and which will alter the balance of light and shadow too. Easy opportunities not always taken.
