I'm not sure if we were meant to combine them into one image or something, but here's what i did with the picture of the doggies...
- I cropped the image, then used a combination of Levels and Shadow/highlight to even out the lights and darks.
- I duplicated the layer, desaturated it then set it to "Multiply". I also made a layer mask for this layer to stop the shadows under the dog's chin from clipping.
- I created a new layer, filled it with white, then applied a bunch of noise to give the impression of a lot of film grain (about 135, I believe). I set this mode to "soft light" and reduced the opacity a bit until it looked good).
- I created a new layer, filled it with black, then created a layer mask for it. On this layer mask i painted with a low opacity brush (varying between 10 and 20%) to allow details to come through. A kind of dodging, if you will.
- I then boosted the saturation of the background layer, as the colour had been somewhat removed.
- Finally, I used a border layer - it's a white layer with black painted on it and set to lighten. This lets the layers underneath show through the black, while the whit hides those layers. This border layer i got on the CD that came with the July 2007 issue of Digital Camera World. (it also has a tutorial for this technique in it.)
It is a little dark, but just now I slid the midpoint slider in levles to the left a little, and the shadow slider to the right a little, and it looks pretty good.
