Sometimes when I scan overexposed negatives there are areas, specifically in the shadow areas that are solid blacks. What can be done to prevent this? I use an Epson Perfection 4490 and scan at 1200 dpi. I've tried scanning at a lower dpi but the results are the same.

Try scanning as a positive. Remember that the shadow is the clear area of the emulsion. *********** REPLY SEPARATOR ***********

Scan resolution isn't the problem. You're clipping image data. Check all of your scanner settings to make sure that you clip as little as possible. Sometimes black and white clipping points are expressed as a percentage. Make that number as small as possible. It can also help to include some of the unexposed film area around the image on the negative, since that scanner software will now treat that as image material, and the film base will have less density than any place in the frame that has detail.

Thanks very much. I am including the clear film border in the scan. I'll check the scanner settings. ________________________________

Scan resolution isn't the problem. You're clipping image data. Check all
of your scanner settings to make sure that you clip as little as possible.
Sometimes black and white clipping points are expressed as a percentage.
Make that number as small as possible. It can also help to include some of
the unexposed film area around the image on the negative, since that scanner
software will now treat that as image material, and the film base will have
less density than any place in the frame that has detail.

Agreed. If you're using the Epson drivers, I recommend using the histogram (levels) feature to set your white point and black point. If the new drivers are like the preceding versions, the histogram view is a bit wanky in that you have to click the "preview" (I think that's how it's labeled...) to actually view the histogram setting effects. Also, I would double check all your sharpening, etc. settings. --- In DigitalBlackandWhiteThePrint@yahoogroups.com, "pdesmidt tds.net" <pdesmidt@...> wrote:
