Alternative to contact printing

I think that getting even enough illumination would be a challenge. It would have to be very consistent I would think for such short exposure times.

However, I do have a vague recollection that Phil once mentioned using a suspended light bulb and a sub-second timer to do the contact printing for a film test exposure. Many years ago so I can't be positive about this.

For the film used to calibrate such a system it may be cheaper to have Fred at the ViewCameraStore just expose the film for your tests.
