Final blog from me, pretty much, until such times as I have opened the Reflex CC Overseas Branch. It will be a short post, you will be glad to hear. Meg is going to take over though there won’t be a post next week as we are both away. Last evening we went to Bath, which was warm and pleasant as any bath should be and dry which is the standout difference from the tub next to your toilet. That and a capital letter wherever it appears in a sentence, of course. Next week’s peripatetic club meeting is at Clevedon Pier, 7:30 pm.
It cannot be denied that a soft sun and Bath stone are pretty much made for each other. I have occasionally watched the Rugby and marvelled as the sun goes down over the city on an Autumn day at just how spectacular it can be. It is the interplay of tones and colours, the angles of the light and its temperature, the degree to which the air is clear or hazed that makes any photograph. It is a basic law of physics that all objects, saving a black hole, reflect right. You don’t hear a great deal about colour theory in photography, it tends to be dealt with as an incidental and a quick reference to a colour wheel and certainly there is more to it than the space I am going to give it, but a little understanding can help when working out how a photograph does or doesn’t work – or indeed might or might not.
Hue is probably the easiest one to discuss for photography because of that much used but frequently misunderstood tool the colour dropper. Hue is measured in degrees (from 0-359) and relates directly to the colour wheel. Not by accident is there a relationship between hue and circularity. The values you see next to the colour dialog relate to the position on the colour wheel. If you want to find a complimentary colour just add 180 to the value (0-179) or subtract 180 (180-359) shown in the box. There are other factors but the principle holds generally good.
Adobe take this further with their free tool Kuler. Now I am assuming that this is the word colour (more likely color) that crawled out of the wreckage of a creative meeting of thirty-somethings’ who just realised that “Kool” had passed to the twenty-somethings’ and their consequent desperate need to prove they still had it (high five), run by a vampire (currently very cool) wearing Google Glasses ™ and loafers who was really a two-hundred-and-twenty-something psychopath with an odd sense of humour who had, in fact, suggested “Culler”. However it is a really useful tool. Dumb spelling, but a really useful tool. This takes you through the primary, secondary and tertiary colours and half a dozen colour/color/kuler/culler rules (analogous, monochromatic, triad, complementary, compound aka composite and shades) as well as having a custom option.
Colour, no doubt, has a psychological impact. If you ever find yourself in a bar where the lighting is getting progressively more blue the closer to closing time, it’s because blue has an end of day effect on us psychologically (note the blue hour) and people are prompted to leave (reddish hues pump up the atmosphere and are used to encourage buying). It can make or break a photograph, there are many times when taking the colour out of a photograph and leaving just tones, textures and lines makes (or saves) an image. There can be some spectacular effects and, of course, in the early days of photography there was no realistic, certainly mass market, alternative to hand colouring. We may not always get to choose the colours we work with in an image but we select the content of each image and colour will have a strong pull on us. If that improvement thing is to work then we need to make it more a conscious part of our photography.
