OK, first my setup: Eos1, 28-135/IS/USM, Kodak Supra 400, and 540EZ flash. I think I am having the same problems most beginners do. My subject is really washed out, deep shadows, or a combo of both. Some pictures even have a heavy shadow on the sides of the room. Any tips or suggestions to eliminate this problem? I am using the auto mode with and without the built in diffuser. I am considering trying the sto-fen diffuser. Anything will help.
