Recently Eileen Fry wrote:We have just started digitizing lantern slide details of greek vase paintings and sculpture for a mythology class using a transparency adapter and are very pleased with the sharpness of the detail, even at low-res.

Eileen --
My guess would have been exactly what you confirmed, that the larger transparencies would scan well even at the lower resolution of a flatbed scanner.
I am curious as to the quality of the scans of the 35mm slides. One of the reasons for scanning 35mm slides at higher resolutions is due to the fact that the percentage they need to be enlarged is fairly high (obviously, depending on the intended use). As a thumbnail image, I would think it would be quite adequate, but for an image that needs to be enlarged to study the details, I would imagine it would not be acceptable.
Unfortunately, these are only educated guesses on my part, and I would like to hear from those of you who have experimented with a flatbed scanner and a transparency adapter. From experience, can someone say what the minimum size of transparency scans well with this type of setup? (Yes, I know, that's a difficult question to answer without knowing what the end uses might be.)
Thanks,
David
