In talking with some graphic pros at work, they have significant concerns with projecting slides that will be used for printing processes. If we want to use these images for presentations, dupes are standard operating proceedure. Now, the first thought is physical damage, which of course is a concern. Turns out projectors are verboten even inhouse - they feel Kodachrome was not really designed for repeated projection use.
The obvious answer to use of duplicates is - how good is the duplicate? I can notice some loss of detail, particularly in shadow areas using a editing viewer. Projected in a classroom, it is less obvious. These are custom lab dups - above average quality. My feeling is you do lose some quality using even the best duplicates. On the other hand, everytime you project a prized orginal some sublime but additive degradation occurs. If its some throw together show where projection conditions are marginal to begin with and interest in subject matter is more a factor than trained-eye appraisal of photographs - I now use dups of favorite shots. Except of course in the greater Tampa area.
