Since I have been searching this and other forums for a decent open-source HDR GUI tool for Linux (since GIMP doesn't really support HDRI due to its 8bit-constraint) and nothing much came up, I decided to share my most recent discovery with you:

Qtpfsgui (http://qtpfsgui.sourceforge.net/) is a GUI tool for the pfs library. Despite having the worst name in programming ever, it seems to be exactly what I'm looking for - and it is actively developed.

Once I have time to get my tripod out to take some pictures for a few HDR tests, I will post the results here.

So long,

Cinepaint supports HDR images. I don't know how active its development is though.

Cinepaint is pretty stagnant nowadays, and it won't do THAT much compared to Qtpfsgui.

Just had a look at Qtpfsgui's features. Very impressive. Now if I hadn't lost the manual to my camera, I would know how to set multiple exposures so that I could create some HDR images using Qtpfsgui... :D

/me heads off to Nikon's website to see if there is a pdf of the manual available...

Easy, put your camera in AV (aperture priority), and only change the shutter speed, let's say:
1/250 for the sky
and 1/50 for the ground , mix them together, and voilá, HDR Cocktail.

(this values are just a example, you have to meter the sky and the ground)

If I knew how to change those settings, then I would most likely already know how to manually adjust the exposure and wouldn't need to refer to the manual... (which I no longer have) :p :D

Very cool find - another tool to add to your HDR toolbox is Krita. I think there are more options coming but as it stands it supports a few hdr formats out of the box and doesn't have the 8 bit per colour limitation that the gimp has. It is however not as mature an app.
