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.
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)
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)
it will be, as most full colour printing is made up of cyan, magenta, yellow and black (cmyk) which is printed on as millions of tiny dots. only on spot colour, or any of the four cmyk colours, will the screen not be apparent.
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)
Ok so the next question is how long do I leave my avatar as it is so that this thread makes any kind of sense!!
