dirty hazy glass (not lens)

[bentley72]

shot this pic at the zoo today, but the glass was rather dirty. is there anyway through post processing to make it less noticable? i'm still learning the editing side of things with Gimp. Any suggestions to edit it out somehow if its possible? thanks

because the look of glass puts a bluish tone on the black parts of his stripes, one thing you can try, and i don't know if it's possible in your program, in photoshop going into "Curves" and adjusting the very bottom nodule on the blue curve (showing where the darks are) and pulling it towards the right, removing the blue hue. then the green curve needs a slight adjustment in the center - because reducing the blue adds yellow everywhere else. it helps remove the look like a bluish glass is right in front... since there are a few reflections show on the right, i just used the "patch" tool to grab small spots at a time and blend them together. here's what mine looks like.[IMG][/IMG]

i just went to the zoo the other day and had to deal with some of the same issues...my solutions didnt work for your photo though, weird! but i did do a B&W version (you probably prefer color though). but i did notice that lightening the photo up, converting to b&w, then using levels to add contrast made the haze not as noticable (just looks like you got some dof going on, the tigers face is in foucs and lots of nice contrast). i kinda like it in B&W, hope you do too

Use levels to add contrast as ntinlizi did. Failing that, a curve adjustment in the Blue and Green channels should do the trick.

thanks for the tips, i will look at the "curves" and see what that can get me. The B&W looks nice too. I didn't think about going that direction with it, it seems to bring out the eye's more

Try hue/saturation. You can go fiddle with just the blues and bring those down and go from there. This will probably make the blueish parts gray but you can make new layer and paint some orange on that and set it to something like soft light which will bring the color to those areas.

The reflections on the right side can be easily cloned out.

Here's my quick version.
