Hi Sam,
thanks for this little shoot-out. Personally I noticed the greatest difference in the cloud detail(zones 8 and 9), and the tonal gradation that the drum scan had versus the Imacon.
now, since I'm a poor photo student, most of my scanning has been taken care of by a local photo center's Imacon. that scanner is SWWEEEEET!!!
just out of curiosity, you mention "The Imacon and the Epson cannot scan higher than 200MB without interpolation, thus making it impossible to make a sharp large print over 30"X40" as compared to a print made from our Heidelberg scan."
please explain further if you could....
I can see the real advantage of a drum scan is for people who print large; like mural LARGE(Peter Lik, other landscapers, etc...) people who also have the budget to afford it.
getting a used Imacon for 4-5k can pay for itself after a year or two, depending on your workflow, and how much you profit off your work.
