Annual General Meeting last session and the picture is broadly good, most importantly the average attendance is up and the finances are sound. Two committee members stood down, Steve Hallam from the Treasurer post (and thirty years on the committee covering just about everything) and Julie Kaye as Competition Secretary and who has conducted and introduced and overhaul of the competition rules as well as run the competition rounds for this season. Club thanks to them both for their service and for making a difference. We are still looking for a replacement for Julie so club members this is your chance to step up. Welcome to Dave Hughes who takes over as Club Secretary.
Next two sessions are about building a panel and will be a pair of group focused practical sessions and an introduction to the Kingswood Salver, a subject to which we will return later in the year. There will be a shoot this next session and an edit and present session the following week. The subject will be shadows, so lets take this opportunity to talk about photographing umbra.
A shadow is a dark figure or image cast on a surface by a body intercepting light. Interpretation of this opens up a huge range of possibilities. The first is do we include all three of the elements involved, the light source, the intervening body, the resulting shadow. The result is a product of contrast, captured by the sensor. Compositionally it is, or can be, quite challenging. Like any other photography it has to be deliberate to be successful.
Perhaps the most effective way of creating a shadow effect is from a single light source, but there are ways of modifying that light before it reaches the intervening body so as to create interest. Gobos are stencils put in between the light source and the background. They are widely used in film and television, and are an easy DIY project for us still photographers and can be very effective.
From portrait session variation to a whole genre, we are talking here of film noir, there are a myriad of possibilities, some very straightforward. However the scale does not have to be large for this little venture to the left side of the histogram.
It is, as ever, about keeping things simple, and the usual suspects: Have one thing that bears the visual weight of the image; Police the boarders of your frame for unwanted intrusions and remove them; Check exposure for the effect you are looking for – high key, low key or on the button; Fill the frame and check the relationship of the foreground to the background; Are the objects in the frame balanced for the maximum impact? What is going to have to be done in post? Colour balanced and depth of field sufficient?
Do silhouettes count? Well yes and no. Yes in that it fits with our definition we started with no in that the silhouette is a dark shape and outline of a subject against a lighter background (i.e. it is back lit) whereas a shadow is a dark area or shape produced by something coming in between the light source and the and a surface. The less picky way of looking at it is that they both produce high contrast areas for effect and the cause of that effect isn’t really important to the outcome.
Silhouettes, by the very nature of their production, are harder where shadows can wrap themselves over the and around the subject, can be soft or hard, can be modified, coloured and generally manipulated for a range of effects. The shadow is also a way of modelling the 2D environment that is a photographic image to give the appearance of something that is 3D. There are plenty of options.
So club, this Thursday, bring your camera, tripod, torches and or flash guns, bring some props to practice on.
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.”
— Paul Caponigro
We did Programme as a camera setting back last November, when an alarming number of members were convinced that Elephants were a European phenomena (you had to be there), possibly confusing them (the pachiderms) with Mammoths, possibly from remembering seeing them at the zoo. This meeting it was the turn of the rest of the dial and no such confusion reigned thanks to the scholarly efforts of Chris Harvey, Gerry Painter, Steve Hallam, Eddie House and Simon Caplan. Between them they had manipulation of the exposure triangle well and truly nailed.
And if we nail the exposure triangle we have the control of light within our grasp. The other thing we need to have control of is what is acceptably sharp in the picture, a function of lens aperture and shutter speed moderated by the selected ISO setting. With these two things nailed in under ten minutes we are a photographer! Our position in the Point and Shoot Pantheon is but a matter of time!
Ah but …. these are the mechanical issues of image capture. Often photographers are as interested in the settings a frame was taken at as the content and whereas they are the key mechanical elements in capturing the image we are viewing they are actually a long, long way down the list of priorities in making a good, bad or outstanding one.
Unless our job is making, marketing and or selling cameras for a living.
The reasons are thus: to plagiarise that image you have to be in the same place, at the same angle, in the same light, focused in the same manner, with the same connection to the same elements within the frame, and using the same size sensor. Even then all you have done is copy. The only thing worth copying is the look and that can be as much about post processing as image capture these days. The valid reason for copying a look is to learn about photography by applying it to other opportunities. The camera settings represent one choice from a multiplicity of options to arrive at the same amount of light captured.
Let’s put it this way: ISO 100, F8, at 1/125th second gathers as much light as ISO 400, F11, at 1/250th of a second, gathers as much light as ISO 1600, F4, at 1/8000th of a second gathers as much light as ISO 200, F32 at 1/15th second. What alters is the depth of field and the relative degree of that in these examples would depend on sensor/film size. This other variable is why we refer to crop factors compared to the old film size “full frame” 35mm standard (so that those of us set in our ways can get a handle on the perspective generated by a given focal length) and perspective is relative, he wrote with entirely deliberate ambiguity.
As we have been plugging the last few weeks rather heavily – and in every blog published for the club, regardless of author – the issue of absolute prime importance is composition. Yes we have to get the mechanicals “right” for the image we have visualised but that will not arrest the attention of our viewer nearly as much as the arrangement of the elements in the frame. The legendary crime/street photographer Weegee, coined the phrase “F8 and be there” when asked what was the secret to success in his photography. Weege used a Speed Graphic 4 x 5 inch camera and a flash bulb for illumination. The point is, know our equipment and how it gets us the results we visualised. To be fare some people ascribe the quote to Robert Kappa but the point remains the same. Being there means we get the chance to get the picture the f stop is only of relevance If you have the camera with you.
Now, we can argue what being there actually implies. and the list would probably be quite lengthy. Most photography to do lists seem to end up that way. Some people even write books about it. Reading photography books is a very good idea, but putting the ideas we draw from them to use is even more productive. Knowing what camera settings other people use can be informative, knowing the performance limitations of our own camera gives us the confidence to experiment. In fact, it could be argued, there are two sorts of photographers who are happy about using Auto/Programme settings. Those who are just starting out and those who are confident enough in their use of the camera to know what it is going to do and when and under what conditions we might have to over ride or compensate. And that leaves us to concentrate on visualisation and composition, which is where the art is coming from.
Most photographers, however, set their cameras to aperture priority and leave them there to control the depth of field. Which is fine. So is shutter priority to control blur. So is manual to control everything, though as a permanent setting does rather slow things down – which can be the point. Auto/Programme is fine. Find one that works for you and use the others to play to their strengths.
Editing this week. Not it in your ed, you understand, but giving 8 images to 30 ‘togs with the aim of seeing what they would come up with in a limited time. Now with this opportunity and the general sharing attitude within the club there were common themes but no two sets of images shown were anyway near the same in detail. Views were shared and how-to’s extended. This is an important point. Whereas Adobe was, by and large, the most commonly used suite in the room, that did not engage everyone’s imagination the same way. The (unfortunate for some) truism that a no-expense-spared camera body and even more expensive lens doesn’t make a poorly conceptualised image a great one extends to the range of photo-editing suites. Proficiency in composition enables more to be got out of the tools in both cases.
If you don’t know where you are going you will probably find yourself somewhere else is a much quoted aphorism in this blog. Visualisation is the first step in making a successful image, more often, than “Sheer dumb luck” (see the previous two blog posts) and imagination is the fuel for the engine of visualisation.
The broader concept which we are progressing here, at the beginning of 2018, is the development of ideas. There are two basic positions which we can take, previously termed by yours truly as the Get-It-Right-In-The-Camera-ista and Ye-Acolyte-Of-Photoshop. More of the former than the latter myself, both points of view have currency, depending on where we are in the pursuit of an image. The more options we give ourselves in the first instance (Get-It-Right-In-The-Camera-ista) the more we are going to have to work with in the second (Ye-Acolyte-Of-Photoshop). Proficiency in both does not guaranty a good shot. If we cannot see the picture in the first place you are not going to get your best shot. If we don’t compose the elements in the frame it is unlikely to be very appealing.
Repetition is a very good teacher, but with the important caveat that we pay attention to what we are doing differently this time – madness lying in doing the same thing over and over again expecting a different result. And for that we need to know what we are working towards and being open to new opportunities as they present themselves. Setting ourselves a project is an excellent development tool.
Initially setting a photographic project needs a brake on the ambition. Make it small, give it a defined beginning and end and give yourself the time to complete it. A two, three or seven day project is a good start if this is all new to you. Take one subject and give ourselves a three to seven days to shoot as many variations of the theme as we can manage. Inside or out. Table top is a really good place to start, the important thing is that we think and think critically about the images we are taking and explore variations.
There are books that do some of the work for you by giving tasks, some easier than others, the idea being we go out and shoot the assignment given to us and print and mount the best one in the book. We can go more DIY and use photocorners or some other mount and a reasonable size note book, something we can write our ideas and reflections on. There are plenty of lists out there for projects we can work through. The thing is not how good is it, but how do I change this for another story? Practical measurements can be taken from the Exif data but the key is much more likely to be in re-ordering the elements in the frame or making the light fall a different way.
What quickly becomes evident is that having a clear end in mind is a good place to start. The journey is where the learning takes place. An essential, when doing this sort of thing over time, is to take notes. The artist’s sketchbook is a centuries old instrument that is a fantastic development tool. It’s for photographers too. The contact sheet, not only a film phenomenon, also has great value but as an extension to a sketchbook rather than a substitute.
So why go to such lengths when we can go back through our photographs, especially those of places we have visited frequently? Well, I am not a very prolific photographer and the hard drive on my lap top contains 49,000 image files, all backed up on an external drive since you ask, with about 10% of those on Flickr in albums. The Flickr account makes it quite easy to go through similarly themed images and I do, occasionally, revisit some of the images on there and re-edit as an experiment, especially the ones from when I was getting back into photography about 5 years ago. Even so I keep a notebook for the odd thought that occurs or note on a method and writing this blog helps put context around what we do each week at club. The lesson from that is volume needs structure if it’s going to be useful. Too much choice is as grievous as too little.
Then there is the reworking of the angles as we looked at when talking about Moving and Zooming in mid-January. Point of view is very important. A picture of a cat or a dog at their level (i.e. ground level) is very different than one taken looking down which reduces the power of the subject in the frame (the opposite is true of looking up, which is why so many Chief Executive pictures are taken from a lower angle and tell us a lot about the person being photographed). Reworking the angles of the light falling on the subject is a key way to affect the mood of a picture.
Basically if we want to improve there are plenty things put there that we can do for ourselves, or we can share with others. Feedback is the breakfast of champions, according to Ken Blanchard, a management consultant rather than a photographer, but nonetheless we have first to create something to reflect and feedback on.
Chair’s night and who should we have as Guest speaker? None other than David Bailey, Yeah, you read me right. David Bailey. The David Bailey, you know, the one that used to work at Asda? One of those 164 David Bailey’s who were used by Samsung to promote the NX1000 back in 2012? Being David Bailey and a photographer has been of the occasional advantage, as David outlined, though any namesake can expect to spend a certain part of their waking day in disambiguation. Especially if, at least part of your day, involves doing the same thing.
David’s theme was on the role of serendipity, the happy accident, which we have looked at as a result of the planned and the purposeful pursuit of the photograph. To be sure there were some very specific happen-stances along the way. Like the NX1000 campaign, where he got to meet the most famous of the David Bailey’s and the over the shoulder query on a London bound train, among others. In between there were long periods of learning. Each and every frame is a learning opportunity, if you have the mindset to turn it into one. Each and every frame is a unique fragment of time and geometry. Whether it is the one we were looking for …..
Bailey, as the 60’s trend for one named photographers labelled him, was, and is, by David’s account, a prodigious producer of frames, sometimes only he can see the difference in. There is a difference to be made here between the practised artist looking for what s/he knows is there and the amateur blindly firing off frames in the hope of hitting on something worth keeping. The camera becomes the instrument of discernment when it is in the hands of someone who can use it as a tool to pursue a clear idea relentlessly. The effect of a planned serendipity, the happy accident that comes from being the right person in the right place at the right time, often lies in the fact that the photographer kept on photographing those small differences until the story gelled with the one they had in mind. In this way photography is as much a process of revealing as constructing.
We have previously referred to four kinds of happy accident:
Firstly: that which is just, or seems to be, random “Sheer dumb luck”.
Secondly: chance from purposely acting towards a defined end running out of “Unluck”, you know the sort of thing, entering photos into competitions, getting feedback, putting that into action, where keeping doing things in search of something particular stirs up the creative pot.
Thirdly: chance favouring the prepared mind (“Sagacity“), that is thinking like and acting purposefully as a photographer as opposed to a person with a camera bumping into photo ops.
Fourthly: the sort that comes from being us, our actions, likes and dislikes, or as the great Victorian politician Benjamin Disraeli put it ” We make our fortunes and we call them fate”. (James Austin: Chase Chance and Creativity).
In Austin’s words David was talking about “Chance interacting with creativity”, here through four evolutionary stages from spray and pray to an ingrained, experience and evidence based work flow. This is not exclusively about style. Style will evolve with practice and a critical eye and determine the way that the forces in the happy accident come together. It will also alter subtly over time. It is about persistence an open mind and the habit of looking, really looking, persistence and anticipation. And persistence. It has long been the case that as a brand you hire Bailey because he is Bailey. You get the Bailey style, the Bailey view. More likely you don’t as he doesn’t do commissions these days, but the point is this has taken decades to evolve and it didn’t happen by itself. And it is still happening.
In the second half David moved to wedding photography as an example of a shoot closer to what the rest of us have a concept of, either as the photographer or the subject, major and/or minor, in illustrating chance interacting with creativity.
There is a long list of “Must have” shots in the expectations of clients. These have grown over the years, farmed by fashion magazines, celebrity weddings, the “Wedding industry” as the costs, technicalities and expectations of the exceptional have grown. It is a journey through a very special day and it has a number of moments in it, actually built in it. Yes these will become the prompts for reminiscences, as will the things that went right and wrong, to other events that came before and after. As time passes photographs move from being a record to being a prompt for triggering those memories.
So stiffed backed and formal are the traditional wedding shots that some of them look like they came off a production line and this in part, I suggest, became a driver for what, in some instances, have become full blown, multi-day, intercontinental celebrations. Yet, even if the day runs on the rails that the timetable of essential images suggests, there will be moments of interaction that make each part unique. Those angles, those interactions as things come together or go their separate ways, children/animals going off script, laughter, the unexpected glint of light from the bride’s father’s shotgun.
Now, note, we can get those through any of the four stages above described. The more developed we are, however, in terms of spotting, forming, framing and taking the opportunities presented, the more of them there will be and the more these things will contribute to our style. In short it is our journey from looking to seeing.ai
An alumni night last club meeting, taken by former club member Tony Cooney covering his tour of Iraq as a Royal Engineer. It is the only time since I have been a member of the club we have actually been short of chairs for an event that became standing room only. Tony brought not only photographs but an interesting array of prints and pieces of kit that augmented a fascinating talk about his experience of, possibly, Britain’s most controversial war of the last 70 years. The Royal Engineers, “Everywhere where duty or glory lead” , have a long and very distinguished history in a role that is as old as the concept of a military. They go where the Army go. Without their skills the Army will not go very far at all. They provide and maintain the infrastructure that keeps the rest moving.
Tony’s pictures were taken at a time when digital was a “new” thing (technically nearly thirty years old but new to most of us) that was beginning to take a hold and film was the only option for “serious” photographers. We have certainly come a long way in the last decade or so. He took both digital and film cameras. At around 2 mega pixels for digital images at the time, you can see the point. Also Tony was using digital before it tipped the selling scales in 2007 which was the first time it outsold film cameras.
Tony stands in a now century old tradition, not always embraced by the authorities, of the squaddie photographer. The very first toted the Kodak Vest Pocket camera of 1912 and the Autographic of 1915, which found Their ways to war in the hands of thousands of regulars, volunteers and enlisted men and not a few women, of all ranks. The Box Brownie (1900-1934) was also vastly popular but nowhere near as robust. This everyman photography was a feature on all sides to a greater or lesser extent (A book has recently been published on the KVP in the trenches written by military historian Jon Cooksey) and its continuing significance as social record should not be underestimated.
Using average wages as a guide, the £1-10 Shillings of a 1912 model Kodak Vest Pocket bought during the Great War would take a £545 chunk out of an average pay-cheque today[i]. Mind you the average wage in 1912 was around £67 a year (about £6,905 in today’s value using inflation as a guide, but between 1912 and 2016 average wages far outstripped inflation). A Kodak Vest Pocket would take about 2% of the average annual wage to purchase, so not a huge chunk of change but substantial enough to ensure most of them, at least initially were probably in Officers hands as it represented more than a week’s wages for many – before we take out the cost of film and processing.
The British Army banned cameras that were not in the hands of Official War Photographers in 1915, for fear of the intelligence it could provide when captured by the enemy. All combatants developed a similar ban. Often it was overlooked and cameras at the Front if not exactly everywhere, were not remarkable but the subjects were and are.
This democratisation of photography, and we should not underestimate the role that the invention and mass production of gelatine based film had on this process – it was the absolutely key driver – produced an invaluable, if widely dispersed, social record of men and women at war, not the sanitised version of the official published record, nor the sensationalised one of the press, but the real lives and routines of the people who were there and the people around them. This is not to diminish the cost of this in lives lost and shattered, but is actually (and thankfully) but a small part of the whole and Tony’s presentation represented that much bigger picture. But when it’s you it is 100%. Tony spoke of the personal cost, how it has taken a long time to get not just the large amount of stories together into something he can show but also the necessary perspective to make the presentation work. Which it did.
Tony also had, not just the kids-everywhere pictures (roughly 40% of Iraq’s population is under 14, and war ranks fifth as the causes of death in the country) with their insatiable curiosity, but also the pictures from a family get together for which they were loaned a camera. For me that added more depth and breadth from what must have been, necessarily, a relatively isolated experience – even if, sometimes, as Tony related, an undeniably and demonstrably dangerous one.
So our thanks to Tony for an excellent evenings presentation, much to think about, and a very great deal to see.

Our speaker this week was Richard Price talking on the very small and the infinite (at least the bit of it we can see) – Macro to Astro. As ever a hugely informative and accessible evening given to a packed hall.
When talking Macro (on a ratio of reproduction to actual size of the subject of 1:1 or greater) we will be including what is close up photography too as there is a technical difference but not, as far as next meetings practical is concerned, no difference worth the time.
These are both areas of photography that appear complicated but, whilst demanding, they can be easily accessed. And they are both absorbing aspects of photography and being both accessible and demanding they teach us a lot about our equipment and how light works with it. It also tells us a lot about our kit and can involve finding work arounds. For instance my manufacturers own 50mm lens will not work on anything but manual and with the depth of field preview button held down with my extension rings. My third party lenses work just fine. Took a while to work out how to get the nifty to work, but it was worth the effort. With a mirrorless camera like mine the DOF preview button is usually redundant -what you see in the view finder is exactly what you get as an image. Only it isn’t redundant at all and I am rather glad it’s there.
Of course, how near/far you want to go is a matter of budget but only really at the extremes. You can get some perfectly acceptable macro shots with a kit lens and a reversing ring (about £7 for a 52mm filter – size it’s written on the front of your lens, in the case of our 52mm example as Ø52). You can also use a coupling ring to reverse one and add another lens to it to make a longer focal length and a greater degree of magnification. In both case it might be advisable to take any UV filters you have off the end of the lens.
The next option Rich gave us was using screw in filters (lenses) of varying dioptres. These are available for around £15 (and upwards depending on filter size), but as with everything else you get what you pay for. Essentially these are like reading glasses for your lens, they are lenses that fit on the end of lenses. If you buy them for the largest filter size you have in your range of lenses you can buy a set of step down rings to fit them to your smaller filter sizes (usually for around £5).
Extension tubes, moving the lens away from the focal plane foreshortening its focusing capacity, use no intermediary glass at all, so there is no risk of flare or softening enhanced by putting more barriers between subject and sensor. By shortening that distance a degree of magnification results by getting closer to the subject. This is generally a more expensive route than the two previously discussed. this is because a certain amount of electronic communication has to be allowed for in the design of the tubes and this complicates the manufacturing process making it more expensive. It isn’t always effective either (see example given above) and work rounds result. However, the more you pay, generally, the more you get in terms of functionality and performance, though this is not an absolute guide.
Finally there is the most expensive option, the dedicated macro lens. Without a doubt this is the higher performer when it comes to producing quality of images in terms of sharpness and contrast, and without a doubt. But all that comes at a cost and even the cheapest all manual lenses cost several hundred pounds. Whichever route we go, macro/close up photography can be done anywhere and relatively easily and cheaply. One extra technique that might help is Focus Stacking. It can be done in Photoshop, as per the link, but failing that you might want to try CombineZP which is free and simple to use.
Now focus stacking as a technique makes a good link to the second half of our evening, Astro-photography. The reason being that photo stacking is an often used technique when taking photographs of the stars. It’s not an absolute requirement, though, and the basics are relatively straightforward. Rich recommended using StarStax, which is freeware, as you were wondering and developed with astro-photography in mind. But we get a little ahead of ourselves.
Dark areas in the UK are few and far between. Light pollution is a serious problem, not just for photographers but for wild life too, in our rather crowded island. Even in designated Dark Areas there are problems at the extremities where towns and villages emit a glow low on the horizon. So it takes some work.
The pollution part is best thought of as the light you would eliminate if you could. The night sky isn’t black, the horizon is always discernible. The sky itself is also quite bright. If we are trying to record as much detail as possible (known as Deep Sky astrophotography) we are going to be fighting the noise generated by the sensor of the camera, especially at higher ISO’s but even at the lowest setting because where there is a signal there will be noise. If we treat the sky as black either by exposing or reducing it to black in post production then the fainter details are going to get lost. The point is the sky isn’t really black, it’s closer to a dirty orange colour. Because of the light pollution and the reflective nature of Earth’s atmosphere.
We can get round this in post by adjusting levels, picking the darkest part of our image as a start point with the eye dropper and adjusting the levels. It’s a matter of trial and error really. As is white balance. Regardless, this will all be a matter of trial and mostly error at the beginning and that is actually part of the fun. Learning new techniques like this means we learn more about the competencies and capabilities of our equipment and allows us to do more things with it.
Our thanks again to Richard and good luck as he takes this and his other presentations on the road.

Macro and close up practical evening. Bring cameras tripods and that reversing ring you just ordered off Amazon.
