So I may have the oppertunity to produce prints from antique glass negitive plates that an aquaintance bought at an auction. Are there any special steps to do this? I know I've got to be careful--they're one of a kind (or at least I imagine they are) shots of buildings from our college campus that have been demoloished over the past hundered years or so. Our darkroom has Besler 23 enlargers and so far I've only found negitive holders for 35mm film. Do I need to find special holders or will this enlarger not work with glass plates? Thanks.
