1. Re: Extracting Photograph Noise as a black and white layer from Photograph
Noel Carboni May 8, 2011 8:36 AM (in response to perfectblue)This is just off the top of my head... You could try something like this:
1. Duplicate the image as a second layer.
2. Run a noise-reduction tool with aggressive settings, possibly multiple times.
3. Set the noise-reduced layer to Difference.
4. Merge layers.
5. Filter - Other - High Pass.
6. Enhance the magnitude of the result with a curves or levels operation.

2. Re: Extracting Photograph Noise as a black and white layer from Photograph
Hobotor May 8, 2011 9:44 AM (in response to perfectblue)To me that just looks like a filter, nothing more.
Noel gave you a rather accurate way of using your reference image, but if you're just looking for the texture try this:
1 Change your image to black and white ( use whatever method you like)
2 go to "filter> sketch>reticulation" and play with the settings as desired
3 Done
Edit: actually, you could just mess around in the filters panel and try some textures, like craquelure etc...
