I have an old family photo, a portion of which i have scanned in and uploaded as my avatar. The printing of it includes a matrix of dots, which I'd like to erase from the original. Any advice on how to go about it?

Does your scanner have a descreen function? I don't know what that is, but makes better photo scans on my one!

if you have photoshop (or poss. photoshop elements (way cheaper)), you could use the despeckle filter.

I've tried despeckle in Paint Shop Pro, but to no effect. I'll see if I can give photoshop a go

Do it at the scanner end as I suggested, rather than muck around with it afterwards, you'll get much better results!

Descreen or anti moire filter will remove any artefacts that look like your avatar.

I think it looks quite "pop art" with the dots.... ;)
May we ask which portion of the photo it is? My money's on someone's kneecap (what a strange sentence) :laugh:

Look at these 2 scans from my scanner, the first a normal scan and the second with descreen activated. See the difference? (look at the blue shading if you can't see what I mean)

Move your money off their kneecap, and put it on their chin and right shoulder:smile:

I'll see if my scanner allows it. Is the mottling present on the original artwork in this case?

a quick google on descreen and paint shop pro brought me to the following advice:

increase the resolution, apply gaussian blur then reduce to original size.

I've applied the Equalize histogram function and the before and after are now shown. Cheers guys (esp. simonali)
