How to clean

The image that goes with this is below in a reply to this post.

One of the problems I run into is present in the attachment. If you look at the blue channel there is a "film" like a dirty window is in front of the image. Presuming I cannot correct by cleaning the actual photo, how might I remove the "dirt" in Photoshop?? I am using 7.01.

Hmmmm, not much luck. If you keep the file size to 100K or under, and save as a .jpg, you shouldn't have any problem attaching it. Welcome to the site, and good luck.

I'm not sure what you mean by dirt in the blue channel. Maybe you're talking about jpg artifacts? Anyhow, I took a quick shot at it. Basically what I did was to take a reading of the pupil of an eye for color information since we know it's black. I found the red channel was lacking, so I made a curves adjustment layer, and targeted the red channel. Then I held down ctrl. and clicked on the pupil to find my red channel point in the pupil of the eye. I then used the up arrow on the keyboard to bring it to within one point of the blue and green channels. I did the same thing with the white of the eye (even though this is not a pure white), then made a contrast adjustment in the curves dialog box, but under the RBG mode. I didn't do anything with the other damage. Maybe someone else will let me know if I'm on the right track or not.

Such a precious couple of kids!

I started by looking at the individual channels, and using Alien Skin's Image Doctor/JPEG repair on a couple of layers. I then put the channels back together again, and added a layer of the green channel with the blend mode set to luminocity. I merged these, and put this layer over a copy of the original image. I used clarify on the original layer.

On the jpg repaired layer, I used grey world color balance, and then automatic color balance. I set this layer to color legacy blend mode, and merged with the original layer.

I then took some of the better color areas, selected the color, and using change to color, target, I got rid of the worst of the yellowing.

I then used the clone brush and the smudge brush to repair the damage at the bottom.

If you would like an uncompressed full size version, say as a tif file, let me know, and I'll email it to you.

It could still use a bit more cleanup work, I only spent about an hour on it.
