DIY large format enlarger
Successful experiment to to use 100 yr old field camera as the enlarger for the 5×7 negatives taken with it. Key breakthrough was using a kindle then an ipad as the uniform light source. Now I can make 10×8 prints instead of just contact prints from these negatives (x-ray film). Initial horizontal test to establish distance needed (40cm) then tripod mounted. Just the light leaks to seal and we are good to go.
