Aggie,
Calumet used to have a video, "Photographing with Fred Picker" with a lot of hands on and two or three sample shoots. He used a 4x5 or 8x10 throughout. I concur with Steve that playing with the camera itself is a great learning tool. If it looks good on the ground glass it will look good on the film.

I'm not sure if the Picker video is still available. I tried to look, but their website lists 479 videos, with no good search facility.

You might want to give them a call, 1-800-CALUMET

Take care,
Tom
