The Direction of Light
Front light is when the light comes from behind you and hits the front of your subject directly. Front light can be unforgiving, washing out colors and minimizing textures. So if you are going to use it, it’s best to do so when the sun is low in the sky when it is warmer and softer.
Backlight is when the sun is directly in front of you and behind your subject, lighting it from behind. I love backlight because the deep contrast between the highlights and shadows is so dramatic.
Backlighting is also perfect for making silhouettes when you have subjects with great shapes.
Sidelight is when the sun is beside you, lighting your subject from the side. This kind of light is excellent for emphasizing shape and texture.
