Haha!!! Lol, another Slide/Loupe addict like me! One day I will do an awesome drum scan from Velvia, Provia and E100 to compare them to loupe viewing!
Love the loupe!!!🙂🙂🙂
Welcome to the club
🙂.
I've done such tests several times: Drum scans with real drum scanner (Heidelberg Tango, ICG 370) and with virtual drum scanner (Hasselblad X5) and compared these scans to both projection and slide loupe viewing.
I used the Schneider-Kreuznach 4x (for 35mm) and 3x (for medium format) and 10x (for both) loupes.
Also the Rodenstock 4x and Peak Anastigmat 4x loupes.
And the Adox 10x loupe.
All these loupes deliver outstanding quality: Maximum sharpness and resolution (especially the Schneider, Rodenstock and Peak), no CA, no distortion, and you get this typical "3D-effect" from slide film.
With these loupes you don't have any quality losses. You can enjoy the full quality of the slides without any compromise.
The same is valid for slide projection with excellent projection lenses!
With drum scans the results are the following:
- a little less resolution
- no "3D-effect"
- real drum scanners can get lots of details from shadows and highlights (an under- or overexposed image can be saved by a drum scan).
A drum scan viewed on a computer monitor cannot match a slide projected or under an excellent slide loupe. But that is mainly because of the severe quality limitations of the computer monitor.
Drum scans are the best tool to make excellent prints (on silver-halide photo paper) from slides. I do that quite regularly when I want some prints from my best slides hanging on the wall, in addition to my usual slide projection.
