I have a similar zoom slide duplicator. I used it with a Pentax and a Nikon. It is quite handy if you want to crop part of the slide but I remember flatness used to be a bit of a bother.Quote:

Unfortunately last time I duped a slide was more than 4-5 years ago so I can't remember too many details on the preflashing. (Have to dig up my notes - if I can remember where I stored them :D)
I'm using a Nikon Super Coolscan 8000 ED and scanning at 4000dpi. At that level of resolution, the image files are quite large and the resolution in the projected dupes is good.Quote:

With ordinary color slide film, you will encounter contrast build-up and you may need to pre-flash the film to correct this.
How about contact printing onto duping film under a colour enlarger? At least then its easy to make colour corrections and there are no intermediate optics.
