Stained Photo (stuck to glass)

[Bluewing]

Awhile back ago I posted a photo that I needed help with and you came through with flying colors on teaching me how you did it. Well this one many be extremely easy for you but for some reason I am not getting it with deleting the red channel. So I though I would let you great people tell me how you would fix it.

Thanks

I'm not a retoucher, but I think there is a little improvement here.

Clone tool
healing brush
burn and dodge
3rd party airbrush
patch tool

gave this a try
duplicated layer
selected green channel copied and pasted blending mode to luminosity
new layer blending mode to color selected color near dress and shoulder painted over remaining discoloration
new layer selected area under chin painted area to blend area blending mode to color
noiseware to reduce noise slightly
turned off back ground layer merged visible
new layer
gradient on this layer with the redish color from the upper right and greyish color from area near right shoulder
masked out female
came up with this

The 1st thing I would do is Image > Duplicate to make a copy of the image. Convert the image to LAB color mode. Ctrl 1 to select the Lightness channel. Then apply a mild setting of a noise filter - I used Noiseware on the default setting. The L channel did not have much of that swirly moire pattern. Application of the noise filter eliminates the majority of it and at the same time cleans up much of the dirt in the dress at the bottom left. Now that you have a more balanced grayscale image, select all and copy and paste the L channel onto you original image. Now change the Blend Mode of that new layer to Luminosity. The areas missing color are still present but the luminosity is pretty even with the colored areas. Now add a blank layer on top of the image and set the blend mode to color. Using a soft brush hold the Alt key to sample color from an adjacent spot on the face that has good color and just paint over the adjacent areas that have damage. This will quickly clean up the face. Do the same with the background and other areas where the tone matches. Where you still have dark spots and things to fix, the clone and patch tools will help you clean things up. When your done a Curve adj layer will be needed to tweak the overall image contrast. You may also find a Hue/Sat adjust layer useful to fine tune.

I mostly used “match colors” & a “color replacement”.
Then, I applied cloning, Noisware, curves adjustments & some high pass filter.

First off great job in fixing the photo. It's interesting to see what tools do different for other users. Chillin anyway you could be a little more specific on how you achieve it using the methods that you stated? Seems I might be missing something regarding matching color & color replacement.

Again thanks to everyone for stepping up and helping.
