Howtek 8000 Drum vs. Epson V850 flatbed scanners

[Alan Klein]

Here's a comparison between Howtek HiResolve 8000 drum scanner and Epson V850 flatbed.

Negative is mine, Tmax 100, processed normal by North Coast Photo dip and dunk with Clayton F76+ developer (similar to Kodak D76). Taken on a Chamonix 45H-1, Schneider Symmar APO 150mm with B+W orange filter.

I'm thankful to Peter Figen of Los Angeles who performed the scan on his Howtek. The scan was done at 4000 ppi using the native aperture (6.35 microns) for that resolution. It’s 16 bit RGB directly into Gamma 2.2 Adobe RGB color space. Peter provided both non-Adjusted and adjusted TIFF files. Note the adjusted version was changed only to set the clipping points using Trident. I did not sharpen either of his files.

I did the scans on my V850 using Epsonscan. The first scan was done at 4800 ppi reduced to 4000 for the first comparison set. The second scan was done at 2400 as I found for some reason it was sharper after sharpening than the 4800 scan. That could be an error on my part. Both scans were adjusted to set the clipping points only. I used Color Comparison set but without Continuous Auto Color Control. Display gamma 2.2The second comparison set (2400ppi) was sharpened in Lightroom 6 purchased version. Sharpen 108, Radius .7, Detail 25. I used Irfanview for the comparison view reducing to approximately 1900x1200 for display on this site.
