I have been asked to copy some old colourised family prints for a friend. The print has a stipple to it as per the attachment, which gives a pattern of dots in the image which shows up in the file. I shot it in light from a window, as I thought that it may do a better job than lights. It's about a 12"x16" print so I can't scan it fully on my V800. I tried on part of it and still get the stipple. I'm at a loss to know whether I can get my lights set up to minimise the dots.
All suggestions will be gratefully received.

Try a diffused light source similar to what you would use on reflective metal surfaces.

Thanks. What I posted was with a soft box. I guess that I can try putting a sheet in front of it.

Try using the Fast Fourier Transform (FFT) method. You will find discussions on this method at RetoruchPRO in the Restoration forum. This is an often encountered problem when restoring old photographs which were printed on textured paper. Here is a link to a good tutorial: http://retouchpro.com/tutorials/?m=show&id=185 (http://retouchpro.com/tutorials/?m=show&id=185)

Thanks Larry. That's exactly what I am after. It's Windows only unfortunately. I'll try installing PS in my Parallels environment and see how it goes.
-
If you search the forum further you may find a solution for Macs using an alternative Fast Fourier Transforms available for a Mac.

Or multiple light sources (classic copying setup with 2 lights at 45 degrees)?

I spent a lot of time looking for a Mac solution. Jimage did come up but my brain exploded reading about it. I'll keep looking. It would be simpler to get PS running on Parallels.
I've tried all the obvious lighting techniques, but the dots are always there.
-
And now, I have managed to install CC under Parallels on my Mac but it didn't work and I'm not willing to play around with my environment as I need it for earning money. When I tried uninstalling CC it doesn't uninstall, says it finished with errors and is still there. My first attempt to report the error to Adobe let me enter my text, demanded that I login even though I was, then fell over, and finally, asked me for feedback on how they had done.
I give up. Until someone gets FFT going for Mac, I'll avoid such challenges.

Just when I thought that it was all too hard: http://www.djjoofa.com/download It looks promising. You need to watch the YouTube video too: https://www.youtube.com/watch?v=SUqsm9_iCbQ

This looks like the silk textured paper, that was pretty common in the 60's. One physical way to remove the texture is to shoot the print while it is submerged in a shallow pan of water. Of course you should take care and test the print to see if water could damage it before proceeding!!!!!
-
Thanks John. This is a family treasure for my friends. I suspect that submerging it in water may not be well received. I don't think that I could do it, far too much stress.
