Scan looks "solarized"???

stradibarrius · Nov 6, 2009

Here is a scan of a B&W print of a violin. The print is relatively dark by design to give it a dramatic look.
The problem is when I scanned the print to post it it becomes "solarized"
I am running a Windows 7 machine with an Epson V500 scanner.
I have the scanner set for "reflective" opposed to film, B&W, 600 dpi

Here is the scan. Help please...

Way to much contrast and black sturation. You have "dramatized" too far.

I didn't saturate or do anything to this photo. I have no adjustment for saturation contrast or any other adjustment.

There is a "threshold" adjustment???

What software are you using? If epsonscan, try the advanced option.

If you have a choice between text and photo, make sure it's on photo. This looks like what happens when you scan something that's a mix of text and photos and set it for the text.

So far you're asking us to tell you what you did wrong, but we haven't a clue as to what you did. How about you start by telling us how this was scanned, i.e., what settings did you use, in detail, step by step.

Looks like you chose a preset in EpsonScan which was not designed for black & white film.

So....what DID you do?

The image is posterized, not solarized. Check your scan settings -- you might have selected b&w document or line drawing instead of grayscale image.

Epson V500 scanner settings
Mode + professional
Auto exposure type = photo
Image type = B&W
Resolution = 600 dpi
Image option = none
Doc. size = 8.5 x 11
target size - original
Threshold = 24 (in the first attachment the threshold was 110)

there is no "advanced" option. I can go to configuration but there is nothing there that deals with this issue. there are options for neg. size etc.

Some one a t APUG suggested I change the "image type" from B&W to gray scale and that was the trick. pschwart I had the exposure type set to photo but had the image type set to B&W rather than 8 or 16 bit gray scale. I set it to 16 bit grayscale and at least I got the image in a B&W photo form.

Thanks for the help!

Hi

essentially what is happening here is that you have extreme contrast.

So ... looking at your parameters it is clear what you have done wrong

wrong ... this will give you just what it says ... BLACK and WHITE

your image is just that ... black and white.

your intended desire is to have some shades of grey inbetween?

so you should use greyscale

I think that will solve your issue

8 bit will be a good start, and if your using photoshop you may wish to use 16 bit at the scan, adjust to desire then convert to 8 bit at that point
