This is my first attempt at the WWYD thread. I couldn't think of anything particularly creative or clever, so I just tried to brighten the photo up a bit.
- Copied and pasted photo in new layer (so I had a bottom layer and a top layer)
- Adjusted curves of top layer to bring out the colors more, and adjusted levels to re-brighten the photo
- Gaussian blur on top layer at 5px, set blending mode to overlay and reduced opacity to 40%
- Dust and scratches filter on bottom layer at default settings
- Sharpened bottom layer a whole lot with unsharp mask (enough so that it looked very unnatural on its own)
- Used Film Grain filter on bottom layer, settings Grain 1, Highlight Area 0, Intensity 1
