One thing I learned about outdoor photography that makes sense, but never occurred to me, is the need to often force the flash even in sunny conditions. This is especially helpful when shooting in shade or areas where sunlight comes through trees and casts odd shadows. Forcing the flash gives more vibrant true colors and removes the shadows. I also highly recommend using a tripod and remote or timer for perfectly still and focused photos, maybe even slow the shutter speed for extended exposure for new effects. These are probably old news to you, but these are discoveries as a newbie that have helped me the most with outdoor shooting.
Kate Shorey Ironically I turn off the flash, even in darkened conditions like dusk.. less glare and better lighting, at least on people. I will have to try using the flash for sunny pix! Thx, Kate in Bristol, Connecticut
