Good light will help anything look good. This shot was done at sunset with a model running back and forth in front of me. I took lots of shots. I was a little late to the party so by the time she got sweaty enough to look like she was really working out, the sun had gone down and the idiot photographer (me) left his flash in the car. No fill light. So it was in silhouette shot. . . ahhhh!
So know when the sunrise or sunset will happen. If you can afford it I HIGHLY advise hiring a model and try some setup shots. You need to plan this and know what your trying to get. It is also fun to pick out bright cloths for her/him and dress her/him for specific concepts you might have. Stock agencies love simple concept shots with room for copy. You need a model and sometimes a location release if the location is recognizable. The release MUST be exchanged with money or something tangible to really be legit. Don’t take advantage…. be fair.
