I seem to be missing posts. They’re not even in my junk folder, which is where most of the PDML goes for some reason.
Anyway, I have a pdf copy of the Pentax extension tubes manual which I found online somewhere, and which is probably still available. It includes charts and so on about what you need to photograph things at what scale. Try a 50mm lens with tubes 2+3. That should give you more or less 1:1 magnification of a 24x36mm area (ie 35mm negative) with film-subject distance of 204mm and an exposure factor of x3.8. The rest you can crop. This worked for me when I was playing around with copying slides. But since you have all the gear, and presumably a digital camera, it should be easy enough to find out by trial and error. > On 16 Jan 2025, at 15:08, John Sessoms <sesso...@earthlink.net> wrote: > > I would probably use a telephoto at closest focus & then crop a lot ... > > IN FACT, I just remembered doing that once before ... > > Thanks. > >> On 1/15/2025 6:42 AM, Ralf R Radermacher wrote: >> I'm hopeless at tabletop photography and I already get the willies when I >> need to take photos for selling stuff on ebay.
