Photographers can become obsessed by lighting, yet many of us ignore the effect the angle of the sun can have on the pictures we take. Most people know the best times for photography are early in the morning and late in the afternoon, and many are aware that the low sun angle produces elongated shadows, which lend definition to subjects. But sun angle can have other effects on the ways in which digital camera sensor records the tones in image files. Understanding these effects can not only help you to use your camera more effectively; it can also illustrate the value of having equipment reviewed in the lighting conditions that apply where you live.
