Summer is a great time for working with dynamic light sources. The best in fact. This is the time I like to get out and just pick a subject and watch how it reacts as the sun moves around it in the final hour of light. It will change more during this time than any other. And after the cold grey days of Winter and Spring, I can’t wait to see this stuff again.
One thing I like to do a lot for more often, as with this shot, is use a telephoto lens to separate your subject even more. It really helps stand out the parts of the image you need to shine. It also allows you to blur out the background more if you don’t have a lens that can open up wide enough. Or you just want to look cooler when your out shooting ;P
