list of post processing techniques

Can we start a list of post processing techniques here and show the resulting images before and after?

Wonderful idea! Hmmm.. this is the Orton effect. The second being the pp photo.

Explaination of techinique and steps to it explained here: http://www.photography.ca/blog/?p=383

But we should include the PP steps to-don't you think?

This would be HDR (High Dynamic Range). The original photo had three exposures (this being the "0" exposure) and using Photomatrix i got the last image.

I would think it would be nice to see everyone collecting both the steps and the examples together for the forum to use. I have a few I will post showing the ones I have found, but once this or if this works can I delete my initial posts that are not of example work, so we can keep this post simple and readiable?
