Originally posted by WPRESTO I have a Pentax bellows with a slide/negative device, but it did not work properly with my K3 as it really requires a 50mm lens and a FF sensor (experimented with 35, 40, 50 and 70mm lenses, but none could be focused and also provide full-frame coverage of the chrome I was attempting to digitize). I intend to experiment more with my new K1. High contrast is a problem, but might be tamed by using HDR, Color is problem: try strobe, incandescent, LED, flood lights, direct light, reflection from a Kodak neutral white card). Color balance of digital conversions is another headache. I've found the "auto-tone" in PS (NOT the one in LR) frequently but not always will give more satisfactory colors than I can manage with 30 minutes of fiddling with the LR sliders. When I have a flat image, I always give the PS auto-tone a try and have been amazed at what it will do with what I thought was a worthless image file. Dust is a PP time-&-trouble phenomenon, just as eliminating dust when giving a traditional slide show was essentially impossible no matter how much time you spent with brush and blower.
David Hancock has a video on Youtube on how to do it. You need bellows and extension tubes, but even then you don't get full coverage.
I am not sure if that's crazy, but I kind of worry about the number of shutter actuations with this set up. Using HDR approach, you get 108 actuations with just one roll of film, that's over a thousand with 10 rolls. What's 10 rolls? I remember reading that K-1 (not that I have it) shutter is rated for 300,000 actuations. 100 rolls is over 10,000, that's beginning to cut into that 300,000... If a $250 scanner breaks down, that's fine, but a K-1 is more pricey. I can see the DSLR scanner used for high-quality scans of selected negatives, but I am not sure if that's the best approach for digitizing 30 years of film...
