Hi Sue, we are get pushed partners for next week. Woo hoo!!! For your challenge it’s all about rim lighting. I Love rim lighting. It is great for people shots but can be done with other items or subjects too. Rim lighting can be done by having the sun somewhat behind or off to the side of the subject (sometimes I use fill flash with those shots so the front isn’t too dark. You can use lights behind the subject, or even create the look with photoshop.
