I have some experience of duping slides to slide film, using the
Kodak dupe film which comes in two flavours, daylight (for flash)
and halogen. I use my enlarger with a colour head, and the lens
is the standard 50 mm N*k*n EL. First class enlarger lenses have
very flat fields and good corner-to corner sharpness when stopped
down 1 -- 2 stops. (Never stop down all the way. I found a distinct
reduction in crispness at f/11 and beyond, due to diffraction.) You
may have to modify the neg holder or jury-rig a new one to show
the entire image. Remember however that flatness is all!
Under the enlarger head I put the OM body, lens mount up and
with a 7 or 124 mm non-auto extension ring in order to circumvent
the auto diaphragm mechanism. On it, I put a white card. I set
the enlargement to 1:1 on this card, then remove it, lower the head
until I can see a focused image on the screen (a Varimagni finder
is usually necessary unless you have at least one eye on a gooseneck)
and lock head position and bellows extension. Then just change
slides and expose. You will of course have to experiment a little
with exposure and colour settings, but as I did, you can get dupes
which you can project side by side with the originals, and experienced
photogs cannot tell which are which.
