Pardon my ignorance, but what were these used for.....I imagine it was most often a color thing.?
Can you make a color print from a color slide.?
Are the carriers useful for anything other than holding a slide.?
thank you
In the past there were colour reversal papers, to make prints from slides.
(Technically correct would be: papers that yield a positive image from a positive, as there were not only reversal papers.)
If one makes sandwhiches out of several film frames, instead of placing them between the glass-panes of a standard stage one might mount them seperately between two 5x5cm, glass panes and put the stack in a slide stage. It just came to my mind...
It was also possible to use your enlarger as a light source to make duplicate slides or internegatives. The Beseler professional slide duplicator used enlarger type carriers to hold slides in place. And yes there were several different processes to make color prints directly from color slides in the darkroom.
Yes, at one time it was possible to print slides directly in the darkroom. Ilfochrome/Cibachrome was one process that was well liked. Kodak (and likely others) has direct positive papers and chemistry as well.
I have yet to try printing slides on Ilford's direct positive B&W paper, but maybe one of these days ...
