Re: Fixing mottled look on face

here's what i mean about using the fft filter. i used it in a very non standard way, at least for what we usally do here on RP. i applied fft rgb to the background image as normal, but then i just did some cloning on that result to get rid of the noise in the middle. that seemed to be where the most mottling and cracking seemed to reside.

this is not great, but i did get a bit of improvement without losing too much detail. this was entirely experimental. oh, and before doing any of this i multiplied the image by 300%. more experimenting would be good. we might well be able to employ the fft filter for more than just removing a pattern.

Nice job Ro. Got to know when to quit - sleep is important
Cheating is good too

Craig, use of the filter interesting - initially tried this myself but did not get anywhere so gave up. I still wonder if a full colour scan would enable more improvement

tony, i had to do a lot of fumbling around to get any decent results, but i did get a little. more experimentation would be needed.

Re: Fixing mottled look on face

ok, i broke down and just did it the old fashioned way, by hand. this is 90% smudge/push with a smidgen of airbrush and erase. i only did the face because, one, it's a lot of work, and two, byRo did such a good job on the rest of it.

Shame on you Craig I was looking forward to seeing further results of your experimentation with FFT.

Still, a very nice job the old fashioned way

Re: Fixing mottled look on face

It's an interesting photo, but kind of a shame to spend much effort on such a low-res scan. I've been playing with it myself but there's not much to work with. Any chance of getting a 1) much higher-res one, and 2) better yet, in color?

2) With another copy of the original apply the Median filter until the cracks disappear (most of the image will too!). I used radius 7.
3) Make a Levels adjustment layer above the Median layer and Group these two together.
4) Use the HP layer as a mask for the group, and adjust the Levels layer to taste.

This is what I got...

What is the process to apply a layer as a mask to another layer (or group) as you suggest in step 4. I've tried selecting the group layer & then dragging the HP layer to the Add Layer Mask Icon but that just creates a regular mask.

Re: Fixing mottled look on face

I think I agree with flora...
instead of trying to smooth or overfilter it ...I think I would try to keep it antique-like to perserve the remaining details in her face maybe playing with the contrast or shadows

I've found a way through Calculations. Apply the layer to itself, blend normal, create new channel, load channel, select group layer, apply mask. Whew hew!
