Color Negative Scanning

320 pixels per inch should give you perfect results in the final print.

For an 8×10, scan at 8×320 by 10×320 pixels, and perform any appropriate color corrections or other changes.

Finally sharpen the image using Filter>Sharpen>Unsharp Mask, radius 1.6, 70 percent, 0 threshold. YMMV, so consider these starting values.

There are those who believe that scanning at the highest optical resolution is mandatory. You may scan at a higher resolution, but the resulting print will be softer unless you boost the Unsharp Mask radius to correspond to the larger resolution. For example, if your image is 400 ppi, increase the USM radius to 2.0.

When I scan, I get a picture with a strong blue cast. What’s the best way to get rid of it (I thought that the scanner, having been told that the negative was a color type, would automatically do away with the blue cast.

Finally sharpen the image using Filter>Sharpen>Unsharp Mask, radius 1.6, 70
percent, 0 threshold.

Why these particular settings?

Don’t know what YMMV means………

What is the mathematical relationship between ppi and Radius?

You’re right – the cast should go away. Try fiddling with the settings some more, and scan a different negative. If the blue cast does not go away, there is for a procedure for removing the cast:

Finally sharpen the image using Filter>Sharpen>Unsharp Mask, radius
1.6, 70
percent, 0 threshold.

Double the radius, double the ppi.

What scanning software are you using? Is there a setting for your _particular_ color negative film?

The resulting print should have between 200 and 300 pixels per inch. So, use whatever scanning resolution will result in that size of file. Jim

I’m using the software that came with my Epson 3200 Perfection Pro.

Hi Jim,

I’m using the Canon 8400F flatbed scanner. I just scanned some color negative film at 3200 DPI (tops for this unit). I then reduced the resolution in PS 8 to 300 ppi with the finished pictures. Works pretty good.

Best,

I may be using a slightly different version of Epson Twain, but in the scan dialog there may be a button with a circle divided into red, green & blue thirds. Click that and you’ll see an eyedropper with the option to set Gray Balance Intensity. 100% gray balance intensity makes whatever you click with the eyedropper a completely neutral color. Try that.

If your photos still look blue (and Photoshop’s Info palette shows you have a neutral tone) then you have other color management problems.

Well I have been told by some others in my photo club’s digital group to scan at the maximum levels your scanner can do and then modify the dpi settings in PS on a duplicate of the origional image. The club I belong to has a Nikon Coolscan negative/slide scanner that scans at 4000 dpi and the results are incredible. As for the 6×9 negative the Coolscan doesn’t do that size so a flatbed is your best chice…Again scan at the maximum your scanner can do therefore you will get all your details in your repront.
