Canoscan 8400F bad scan results

Scaner often outputs full color backgrounds to black and white objects. Or, it will scan a black and white object then print the fonts in some faint green, red or blue color. Or, it will print an all red background!

Can I scan a negative 4X5 black\white to make a photo


In general, yes, you can scan a negative and make a photo from it. I don't really know your model scanner, my Canon 8400f has a film adapter and a light in the cover, but would have to scan a 4x5 in sections and I would have to piece it together after scanning.
The results I get from scanning negs are very good, as good as I ever got in my darkroom.

Don't use Descreen. That is for scanning things such as Magazines that, when looked at very close, appears to have a lot of little dots that can cause a moire pattern when scanned.

Grayblue Background on scans


A color scan will give real output as it is. If the background is grey, the output will also be grey. If you select 256 Color output, there may be small change in color, as compared to the original. If you select grey output, all colors will be converted to Grey. If these files are converted to PDF, it will be same, except in ODF format.

If you select B&W you can save the file in TIFF format. Unlike grey or color, each pixel can be either black or white only. To scan in black and white you must select right brightness. By doing os you can eliminate background (technically noise) and capture foreground(data)
