SUNLIGHT
Probably the most valuable times of the day for general colour photography | are the early morning and late afternoon into evening . Low , raking sunlight is especially good for revealing the texture of a landscape , and long shadows can help to pick out subjects dramatically against dark backgrounds . The low angle also gives the biggest choice of direction : by shooting into the sun you can create silhouettes , side - lighting gives good texture and contrast of detail , while frontal lighting , with the sun directly behind the camera , can give richly saturated colours . On top of all this , the sun moves relatively quickly at these times of day , so that within the space of just one or two hours you can find a whole range of lighting conditions .
It is almost impossible to tell the difference in a photograph between sun- rise and sunset , unless you know the actual scene . While sunset is usually a more comfortable time of day to work , the advantage of sunrise is that there are fewer people around - useful if you are shooting quiet landscapes . For an important picture , it is worth planning the camera viewpoint and the sun's position ahead of time ; remember that the sun rises and sets at an angle , steeply in the winter , but nearly vertically in the summer .
A high sun is more difficult to work with , even though the middle of the day may well be the most convenient time for travelling and taking pictures . Portraits are rarely attractive under a midday sun - the way that the shadows fall underneath , rather than to one side , is less flattering . Flat landscapes show very few shadows , and this lack of modelling can make them look dull and uninteresting , particularly at a distance . The best subjects for a high angle of sun are often those whch already have strong shapes , strong structure or strong colours and patterns .
RIGHT The vast majority of modern film emulsions are balanced for daylight at noon ( 5500K ) . But although midday may provide the photographer with a wealth of bright and vibrant colours , strong shadows can easily mar pictures .
BELOW AND BELOW RIGHT Early morning and late afternoon into evening are the best times for general photography . The texture of a landscape can be shown to its best advantage in low , reddish sunlight ( below right ) , while reflections of low sunlight on water can lend atmosphere to an evening shot ( below ) .
