How to remove stains or spots from a photo

The actual size of this photo is approximately 2x3. I am suppose to enlarge it to about 8.5x11, however, while attempting to enlarge this photo, I had noticed that the gentlemen jacket and face is completely full of black and orange spots. The woman face is also full of orange or red spots. I would like to know if this photo can be salvage. I had never seen so much spots or stains on a photo like this before. How can I remove those spots from the whole photo?

Spots & Stains

Gerald, the image is salvageable. I only had 3 minutes to play with it (off to work) but you can restore it completely with a little work.
The Blue channel is severely damaged. I used the channel mixer to replace it. Then used Noise Ninja / Neat Image to reduce the color noise and course noise. A quick Hue / Saturation adjustment to move the colors back toward original. I stopped there. You could then clone over the remaining specs which should be mostly light colored, and then resize your image. I recommend you scan the image at a high resolution (at least 1200 dpi).
Regards, Murray

Similar technique to Murray, in that I used one of the other channels.

I copied the Green Channel to an alpha, adjusted with levels, then pasted it into the damaged Blue Channel to replace it.

Sharpened resulting image.

Again, like Murray, it only took a couple of minutes.

Hi there

Thought I'd give it a try... rather then make drastic changes to the blue channel I just blurred it some and used the healing brush on a few places. Still did a little color correction... at least what I thought the colors should be. I found a yellow that did not match so I opened a blank layer set to color and painted some color to hide it.Then a reduce noise filter to finish. Forgot to remove the red and yellow from the eye whites and teeth.

Spots & Stains

Gary & Butch, great work. It is clear from the different versions that the image can readily be manouvered into a good range of skin color which Gerald can fine tune them to.
Gerald, good luck with the restoration.
Regards, Murray

I was blown away from the result of the work that was presented. You guys are very, very, good. I'm amazed of the finish product. I'll see if I can follow some of these directions. Thanks again.

You're welcome Gerald, good luck with your restore. Any problems come back, and I'm sure we'll be able to talk you through them.

Great results Butch and Murray, as usual there's more than one way to skin this cat.

How to remove stains or spots from a photo

Gary Richardson, dude, I'm trying to follow your method, but I got stuck. I clicked on the channel button and checked all of the channels. This was what I had noticed of the channels. First, I clicked on the red channel, the channel turned into a black and white with some spots visible. Second, I clicked on the Green channel and it was a black and white with lots of spots. Third, I clicked on the blue channel and that one looks awful. Because of my limited experience with photoshop cs 2, I don't have a clue on how to copy an alpha channel.

Why did you use the Green Channel instead of the Red Channel? The Red Channel looks better than the Green Channel to me. How did you paste this channel onto the damaged blue channel. When you inspect a channel what do you look for in that channel. Please give me some more information on exactly what you had done. I appreaciated your help because I had given up in trying to fix this photo.

Hi Gerald,

All the channels will look like B&W renditions of your picture. What they are showing is the luminance of the particular colour they represent.

I chose the green channel because its luminance levels were the closest to those of the blue (red is usually radically different to the other two), and would therefore be easier to adjust to the level of the original blue channel.

OK, first open the channels palette. Now drag the green channel to the new channel symbol at the bottom of the palette (its the Square one with the square in the corner). This will create an alpha channel copy.

Rename the new channel as Blue Replacement. Click on it to make it active, then use levels to make it a touch lighter (don't overdo it too much), click between the alpha channel and the blue channel to see if they match (not easy to judge because of the damage to the blue channel.)

When you're happy they look similar, click on the Alpha (Blue Replacement) channel to make it active. Now click Select > All to select the channel, then click Edit > Copy.

Click on the Blue channel to make it active, then click Edit > Paste to replace the blue channel with the Alpha (Blue Replacement) Channel.

Now click on the RGB channel so you can see the effect.

It may be necessary to adjust the overall colour cast of the image if you didn't quite get the levels right on the new blue channel.

Easiest way to do that is with a Color Balance adjustment layer.

Hope this explains things, anything not clear just let me know.
