I just finished my setup to digitize my collection of negative film and slide pictures. I used most Pentax equipment to do it: 1) Pentax *ist DL camera, 2) Pentax Auto Extension Tube K #2 and #1 (31 mm extension) 3) SMC Pentax M 50/1.7 lens 4) Asahi Pentax Slide Copier I used also an aluminium tube and a flash bracket to attach the slide copier. The process: 1) Take the pictures of 36 frame negative film (5 minutes), 2) Invert tand Auto levels with GIMP 2.6 with a Batch Script. The Invert and Auto Levels take less than 1 minute for all 36 frames. The whole process for a film with 36 frames is about 6 minutes. The setup: Following there are some results. The first result is a scan from a 1993 negative film of a portrait of my wife. This one from a Kodak T-Max 100 negative from 1988: This one from a 1993 Kodak Gold 100 negative: Comments and critics are welcome.
