I need help with long lenses for super ULF portraits. Most of my photography work has been with portraits and the majority full length in in the studio with my Canon 5DII.

I'm so impressed with the giant prints made by Richard Learoyd I saw last week in San Francisco that I want to do my work without any post processing in Photoshop, just shoot and then develop the paper. However, I don't know enough about lens coverage and the choices available.

I realize that it would be simple to put a hole in a wall between two rooms and one would be for hanging Ilfochrome paper and the other for the models. So I need a nice bellows to fit on the wall for fine focus and lenses to project 40x72 or thereabouts on to a vertical easel in the "camera" room.

So what lenses are the best options. I'd like to have both soft focus and sharp focus choices with sufficient coverage. Lighting will be by strobes with large close light sources.

The camera room is 12 ft wide.

Your guidance will be much appreciated!
