  1. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

  2. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

    The V600 yields 1560dpi effective (https://www.filmscanner.info/en/EpsonPerfectionV600Photo.html), so the difference is huge.




    The V850 resolves 2900x5.9" in the scan width, totalling +17,000...

    Sandy, have you the way to make a V700 5x7" scan in holder ? Or are you scanning 5x7 on bed with the low resolution lens?

    I ask this because the V700 covers 5.9" with the "Super-Resolution" lens...

  8. Re: Should I Drum Scan, X1 Flextight Scan, or use the Epson V850 w/Aztek Wet Mount Ki

    LOL.

    For 5x7" the Imacon is even more infame regarding resolving power. For 5x7" it scans 8000/5 = 1600 dpi hardware yielding 1400dpi effective in the horizontal axis and 1200 in the vertical one....

    With TP you may get the "usual" LF image quality in a MF shot, and even a careful 35mm shot can be near as sharp as many 4x5" shots. Of course it also has drawbaks.
