PSP tutorial(s)
I just added this to my lj, and thought it would be a good idea to add it here as well. I'm using PSP7, but I suspect this shouldn't be hard to translate to other software.
How to go from this
to this 
1. Duplicate the image. Set the new layer to Darken.
2. Apply a Gaussian Blur, set to 10,00 at least.
3. Duplicate the darkened and blured layer and set to difference.
4. Merge all.
5. Apply Negative image.
6. Duplicate the image and set to Multiply.
7. Duplicate as many times a snecessary until the image is as clear as you want it.
8. Merge all layers. Set to grey scale.
9. Increase colour depth to 16 million (24 bit)
And then, using the two images above, you can get this:
1. Take the charcoal drawing image as a base
2. Paste the original image over it
3. Set to colour
You can also get this:
1. Use the original image as base.
2. Paste the charcoal drawing version over it.
3. Set to Luminance.
4. Adjust the layer's transparency until you get the result you want (should be lowered to at least 80%, for any noticeble results).
It's all pretty straightforward, but if you have any doubts, just ask. I got the first part of the tutorial from here: http://www.hypergurl.com/. The rest was stuff I figured out by fiddling around. The icon I'm using on this message was made using the graphic novel technique.
