Do you often see photos with large "blown-out" areas around light fixtures and windows? Our eyes don't and neither should your photographs. Whats more pleasing to the eye? Patches of harsh highlights and shadows or a natural look. You should not see reflections of the photographers flash in windows or even the photographer. We may use several flashes to get the best results and it takes more time, but we believe its worth it. Finally on the subject of lighting, do you see color casts on your photos? Weird looking yellow splotches or strong blues coming from windows? Our cameras sometimes see these colors and register them on the image, but our eyes don't see them in real life. They should not be there and should be removed before in post.
