Back Lighting - Sunflowers

Sometimes shooting into the sun is difficult.

Sunflowers in the Sun

Back lighting:

"... used to hear people say, “oh, don’t shoot into the sun”, but sometimes shooting into the sun could really give your image a unique look. Backlighting is when the light source is behind your subject. Many times if there are things in the air, such as fog, mist, or even pollution, you can create dramatic images with atmospheric perspective. Unlike front lighting, this will accentuate depth and draw the viewer in." LINK
