Annoying ink problems

Hi guys,

This is my first post, and I have to say you guys have a very interesting forum here!!!
Iíve encountered here two cases similar to a photograph I have.
I have one photo whit blue ink and Iíve removed almost half of it but now Iím stuck in the parts that need more attention, like the eye, mouth and nose.
Iím using Photoshop, Iíve used a lot of tools, like the clone stamp, healing brush, and filters such as Color DeConvolution and others to turn the image to black and white to remove the ink but turning it to black and white reduces a lot the quality of the image and I canít do nothing with it, I only can use it to see what is behind the ink, I even tried to add color to the image but it has a lame quality.
I think Iím give all the information about what Iíve done. Does anyone know a way to remove the rest of the ink?
Here are the two photos, one shows what I tried to explain and the other itís where Iíve reached so far.

Thanks for your attention.

Re: Annoying ink problems

PCadete, welcome to RP. If you examine your orig image you will see that most of the detail is in the Blue Channel.
In the Channels Palette, make a copy of the Blue channel and run a noise filter on it at a mild setting (I used Noiseware). Next go back to the layers Palette and duplicate the background layer. run the noise filter on it as well. With the duplicate layer active, Image>Apply Image and choose the Copy of the Blue Channel as the source, Blend Mode Normal, Opacity = 100% and click OK. Your layer will be gray scale. Change the Blend mode of this layer to Luminosity.
Next create a Merged Visible Layer on top (Ctrl + Alt + Shift + E). Change this new layer's blend mode to Color. ON this new layer, choose a small soft brush, hold down the Alt Key and sample a good skin color adjacent to the ink. Then just paint over the ink. Keep move around and sampling and painting unti the ink is gone. When you are done you may need to make some fine touch ups.
Regards, Murray

Re: Annoying ink problems

hi pcadete and welcome to RP.

larger image sizes would help here

also, i looked at the second picture and it strikes me that the blue is something written on the photo, but there is some reddish brown marks on the face that appear to be actually drawn on the face before the photo was taken. is this correct? and, if it is correct, then do you want to remove just the blue ink or all the marks?

Re: Annoying ink problems

ok, here's why i asked: if you notice how i restored this, it would seem the child has some sort of paint/makeup on, as in, maybe for halloween or something? and, to restore this image without that wouldnt really be a true restore. it's fine that it might not be, if that's what the customer wants, but it's something a restorer shld be aware of and check with the client as to actual wishes.

Re: Annoying ink problems

Guys, thanks for your precious help, in particular to Murray, it was very helpful, I was trying to do what you told me to but not whit the blue channel, I've created a blue image with Color DeConvolution but the results are far from what I now am able to do, the image is almost done but I'm with some problems in my computer and it will take a while to finish it. When I finish it up I'll put here the work done.
Thanks once more.
Regards, Pedro.

The mentioned color deconvolution plug-in is from 4N6site.com (check out some examples there).
I have applied color deconvolution directly to your small jpeg, and even that way it really gets rid of the ink! A more refined approach would be to apply it to the affected areas only. And yes, the child does have a brown painted mustache.

That's an amazing result; especially on a jpeg. it has been a while since i last saw this plugin, so gonna download the trial again to test a little myself.

Thanks Chain, I guess you can see why the color deconvolution plug-in is useful in forensics and in photo restoration! Actually capturing the underlying colors is better than trying to brush the problem away (a last resort in restoration, and not an option in forensics).
