    Epson V850 scan with 100% crop

    Color Cast Removed, Chamonix 45HS-1, Nikkor 75mm f/4.5 at f/32, front tilt, fall. Extar 100. Wet scanned using Betterscanning adjustable holder, ANR glass, Kami Fluid and Optical Mylar. Epson V850 at 4200dpi. I downsized from 4200dpi to 300dpi and saved as jpg, sRGB. I also included the 100% crop of the center of the frame. This was about 2/3 of the way into the image from where I was standing. I still need to fine tune the focus adjustment of the V850 using the holder, but this is pretty close. I don't think it did too bad. Unfortunately, flickr keeps over-saturating uploaded images.

    Steven,

    V850 scans come less digitally optimized than those from Pro scanners, those have amazing (in firmware or in driver) sharpening optimization that increases the effect until it detects overshot condition.

    With a V850 you don't have that automation and always have to adjust sharpening in Ps, these are the settings I would use for this image:

Name:	scr.jpg 
Views:	36 
Size:	96.6 KB 
ID:	184255

    (sharpening 1.4pix , 80%)

    This well known: https://petapixel.com/2017/05/01/160...s-500-scanner/

    From that Petapixel test, we have to realize that as the scan width is increased the V850 shines the more, because the V850 mantains the same resolving power for MF than for LF, while the other zooms out until 2000 samples per inch.

    Another advice is scanning 16bits and not using the limits suggested by the scanning software that tend to clip in the ends of dynamic range to deliver a good tonal curve for the mids.

    So a bit it's like developing a RAW DSLR image, you feed photoshop with a dull image that has "more scene dynamic range" than the presentation medium has, and then you have to bend curves, clip and locally edit to obtain what you want.

    IMHO this scan is not well done because you have little detail in the saturated yellows, you may post an screenshot of the scanning settings.

    You should obtain at least a color gradation like this one, it's a V750 crop of a 35mm shot:

    Since we know Steven is setting up an enlarger, perhaps a comparison of similar scans to optical wet print enlargement.

    Do we have access to any examples?

    I observe that the grain in the expensive scanner detail in the Petapixel article is coarser than the Epson detail, so I took the side-by-side example into Photoshop and sharpened the Epson side until the grain was equal. At that point, to me, the Epson side actually appears noticeably sharper.
    Thanks, but I'd rather just watch:

    There are few possible reasons for this, if you are happy to make available the exact jpg that you uploaded to flickr, I would be happy to make an analysis, when I get time. Doesn't have to be this image just one that has the problem as described.

    I'd prepare some microscope images...

    On the sharpening use high pass and try to avoid too much of it. I rarely use another method, but open to trying. I find too much sharpening or wrong kind while age may look sharper it ends up being garish.

    Sure. I will put in dropbox and send link. Maybe I am just seeing things.
