Hot pixels/reflections in scan? Can Photoshop eliminate them?

HI hope someone can help ,

I scan my paintings and then send the scan to a print house to get them printed. The problem is that as I paint on a fine textured canvas I get some reflections in the dark areas especially. These look like hot pixels?

Is there any way i can get rid of these in Photoshop whilst still keeping the high degree of detail I need in the rest of the scan?

I can't see anyway to post an image here so I have put one on the web - http://www.onlineartdemos.co.uk/pixel-scan.jpg

Thanks for any help you can give, this one has me stumped :eek: .

Not knowing what scan software you use, I can only give a general suggestion: Find the setting for "Matte" in your scanner software. You'll often see a list of options, stating what you are scanning. It should have such options as 'matte, newspaper, magazine, glossy, photo, etc'. Having never painted myself, I don't know the difference between fine-textured canvas and 3000-grit sandpaper, but try that and let us know how you come out. Unfortunately, there is no easy way to do this in Photoshop, only with a steady hand and brush tool, but being an artist you should be able to handle that if we need to go there.

Hi Thanks for the suggestion.

I tried those setting a while back but no joy.

I think in Photoshop there is a toll / setting for hot pixels - menat for RAW files, I was wondering if there was something like that I could use? as the pixels are much lighter than anything else.

How are you scanning? I can't imagine being able to scan a painting canvas on a small desktop flatbed scanner!!

Maybe you could try a professional scanning service--in the states we have Kinkos. Don't know what options you would have.

HI,

Yep scanning with an Epson Perfection 3170 then stitching in Photoshop. It does an excellent job, other than those reflected pixels.

Had it done professionally at a print house - cost me £75 ($150) and nowhere near the quality I got.
