Joel has a great article about HDR on his site. Perhaps I have to steal that again…..

Episode 015: RAW to the rescue! Mini-HDR ;-)
Wednesday, October 17th, 2007
I shot some autumn scenes with a Lensbaby in a very mixed light condition. And I haven’t checked the histogram after this shot. It is the only one with the focus right on spot and a dreamy flair. The leaf in the center was overexposed in the JPG image - blown out highlights ruined the image.
This is the final image - not the one with the blown out highlights….
But I had shot in JPG and NEF (Nikon’s RAW) - so I used UFRaw to produce a TIFF file with the right exposure of the leaf and blended it into the image with a layer mask. This is basically the way (pseudo-) HDR works. Take different parts of the image from differntly exposed photographs.
A slight correction with the hue/saturation tool was necessary to adjust the colours. Cropping was done twice - a mistake made a correction necessary. So I covered some advanced options in cropping.
I promised some links:
- The Lensbabies site
- The Ret Hat Magazine tutorial
- Epsiode 11 about RAW conversion
- The Meet the Gimp! photogroup at 23
Don’t forget to make a triptych and post it in the photogroup. I’ll draw a winner for the one year 23Plus membership sponsored by 23 in show 16. So you have still time to Oct. 18 to submit an entry. The pictures there are already worth to be looked at.
