All curve adjustments, etc., are left to Aftershot and PSP. In fact, that is my goal to achieve a flat image that retains as much highlight and shadow detail from the neg as possible. You mention that scanning leaves flat images, and I am aware of that. Tiff file type = 16 Bit Gray or 48 Bit RGBĪs far as I know, the above are the most relevant to the question, but if I have left something out that matters, please let me know and I can repost. (Note: these settings are left as generic as possible to avoid Vuescan applying its own curves to the scans - I want a straight, flat scan)īlack and white points = NA (disabled if Colour Balance = none)Ĭurve low = 0.001, Curve high = 0.001 (set as low as possible to avoid clipping)īrightness = 1.0 (varies depending on shadow detail I want to retain)

Rather than post screenshots of every tab in Vuescan, here are my basic settings: To answer your last question first - yes, all settings are the same, except selecting 16 Bit Gray or 48 Bit RGB. import problems, albeit in colour) but with no effect.īTW, PSP is updated to latest service pack. But the file size is 3 times larger, which is a drawback I am trying to avoid as the scans are of 6圆 and 6x9 medium format negatives, resulting in 150 to 230 MB files, respectively, if 48 Bit RGB is used.Ĭan anyone suggest a cause and solution to this? Is there a setting in PSP that will allow the 16 Bit Gray scans to import and render normally? FYI, I have tried disabling Colour Management (from reading another thread here re. PSP will render scans of the same negs normally if I set Vuescan to input and TIFF output as 48 Bit RGB (all other settings unchanged). However, in the Vuescan preview pane and Windows Photo Viewer, the images look completely normal.

There is no detail at all in the highlights. As if the negatives were badly underexposed, in other words. Specifically, when I set Vuescan input and output (TIFF file type) to 16 Bit Gray, the resulting scans look completely washed out in PSP X8. I am hoping to get some help with Vuescan settings for scans of monochrome negatives.
