[LargeFormat] Contact frame

[David Galway]

greetings all ...

I am looking for advice on a quick & dirty contact frame to get me going
printing B&W 8x10s on up to 11x14 paper.

I am envisioning a heavy piece of glass on top, perhaps some kind of
dense foam on the bottom. Light source will be a condenser head 35mm
enlarger, in which I will be using contrast filters.

As to the size and kind and thickness, etc, of glass and foam ... or
perhaps other ideas entirely ... I would appreciate any help.

regards
David Galway
