The most beautiful engagement sessions occur in Spring and Fall at the cusp hours of the day. In the warm weather we photograph at dawn or dusk to avoid heat and tourists. In cool weather we photograph during the warmest parts of the day.
If you need an early morning engagement session before work, that is totally fine. In Georgetown we always photograph early to avoid tourists. Anytime 7am-11am works great. At Great Falls we can photograph anytime but the best light is early morning. At the Jefferson we often photograph in early morning to avoid tourists. The Jefferson is the only one of our sites which requires a permit.
Match as colors closely as you can. This makes a huge difference in an image. The easiest thing to do is choose something that looks great on you and match an oxford shirt for him to it. It can be as casual or as dressy as you like. If you would like to wear high heels bring along flats for comfort while you are walking. Jeans and shirts are totally fine too. Sleeveless or 3/4 sleeves look best in photos.
