I'm trying to restore this photo that has faded with a yellow cast. I have attempted to correct it somewhat using Variations in photoshop. I'm looking for more suggestions to improve the colors in this photo.

Thanks for your help!

You can actually get fairly good results on this one just using Image -> Adjustments -> Auto Color. Obviously you'd need to do some general restoration of the image as well, though, and I think the skin tones could probably use a little more work (but you'd want to look at a higher-resolution image for that, obviously).

Hi. I also tried your picture. I used levels and hue and saturation adjustment layers. Also color cast.

I first used auto levels and made a layer. Duplicated twice. Desaturated one of them. Used hue mode to blend. This makes it red and grey mixture. Blended this with the original layer. Applied Unsharp mask.

Thanks for all your suggestions! I'm going to try some of those out.
