Off to Weston we went, aka “Super-Mud”, last meeting and though the skies were lowering the turnout was pretty good and a good time was had by everyone I talked to. What more can you ask for? Well it was Weston Bike Night, organised by the Royal British Legion Riders Branch, and runs every Thursday from May to September. So I hopped on my motorbike and made my quid (£1) donation to the RBL to park on the Marine Parade Lawn and wandered round with my camera, before meeting up with the rest of the club on the beach by the Grand Pier. They had, it turned out, been taking pictures of a convict making his way up the beach, with the express purpose of compositing them into a single photo in post production (Photoshop, Gimp). If you look back through this year’s competition galleries you will get the idea of who and what sort of thing. The sun also made a show right at the end of the day and we were presented with a salmon pink sunset against the grey of the clouds as a finale. Not too shabby.
It is often said, not least by me, that in photography, painting with light, the light is everything. So far so obvious. What we are really saying is that the contrast in any given light situation is everything, as the same subject in different lighting gets a different reaction from its viewer. We are not just talking of low light here, where we have options within the exposure triangle, and in the way the camera works in other ways, but, when the weather is as it was on Weston’s beach and the contrast is low, the temptation is to save it for another day, but we can be missing opportunities. Contrast is what determines how “flat” the light in your image looks. Possibly, most logically, we can see this in monochrome images, but it most definitely applies to colour ones too.
Essentially, contrast comes in two flavours. Thinking of the black and white image and we can imagine the more obvious of these expressed as a tonal range, which we have touched on before. The tonal range is that between (theoretical) absolute black to (theoretical) absolute white which we would affect in post production editing programmes through levels and curves. The second flavour is colour contrast which is about the predominance of a colour in relation to the colours around it.
When we are producing black and white photographs we are really talking producing images constructed of the shades of grey (no tittering at the back). Soft images record little range in those shades, it is all middle and very little of the absolute ends, whereas hard looks stark because we have a band of hard blacks and a band of hard whites and very little in the middle. This is not the same as low key (mostly darker shades of grey surrounded by blacks) and high key images (mostly lighter shades of grey surrounded by whites). The emotional tone that low key images give out tends towards the sombre whereas high keys have a lighter mood, but tonal contrast isn’t just limited to black and white.
Colour, as we have explored before, tends to overwhelm tone when provoking emotion in a viewer, but good tone is a major element in the construction of a colour image too. Because there is more variation in colour, more information to play with, then the possible outcomes are multiplied accordingly. Broadly the more saturated a colour is in relation to the others in the image and relative to its position on the colour wheel. The degree of saturation is also important to colour contrast and that can be affected by exposure (try bracketing a couple of shots by two thirds of a shot and look at them in comparison, warmth, feel/mood can be subtly or not so subtly effected.
Meanwhile, back on the beach at Super-Mud, we are faced with some impressive cloudscapes that are throttling the contrast out of our seascapes, aided and abetted by a distant haze shrouding the South Wales coast. Looking on the (not too) bright side we are not trying to photograph either a black cat in a coal hole or a polar bear in the Arctic). Those both represent zero contrast situations. Give up go home, assuming you survive contact with said cat and/or polar bear. As we are in neither we can do something about our rather dull scene (other than retreat to the pub). All the rules of composition still apply but we are not bereft of options. The exposure triangle was mentioned above and in pushing two of the elements in that, aperture and shutter speed, we could just make a keeper.
Exposure Value Compensation it’s called and it’s that button that allows you to adjust the average that your meter is measuring up or down, usually by up to two or three stops, depending upon what camera you are using. It does not matter whether you are in Shutter or Aperture Priority or shooting in manual (though this is a bit of overkill bearing in mind you already have control of aperture, shutter and ISO in manual mode, but it is possible to employ as another way of under or over exposing from the average). First meter as normal then apply +0.3 ev on the scale. Try again up to a stop, or in the extreme, up to 2 stops or more, basically adding dark. In manual you will possibly be moving in half stop intervals depending on the age of the lens, but most modern ones seem to move in thirds. The same basics apply. Shoot in RAW for the best post production options. What you will do here is affect the colour contrast. Yes the whole image will look progressively darker, but that is not necessarily a bad thing. On the Mini group trip to Weston, where there was a vivid orange sunset, this actually strengthened the composition by allowing the sky and certain reflections to be the focal points against an increasing rich, dark background. Essentially for this technique you are looking to set the narrowest practicable aperture matched with the highest shutter speed you can get a workable image in the light conditions.
Try it next week when we visit Portishead Marina. Dock Gates, 7 pm. See you there.
