HDR – High Dynamic Range – Images under linux



HDR – recently I heard someone talking about this with regards to digital imaging. The idea is that you have three identical images (landscapes) taken from a stationary (tripod) camera. The only difference is the exposure times vary. Together you can blend them to create a more impressive final picture. Yes, I just talked about fake photos and digital imaging. This, to me, is in a different class of photo editing…. enhancement(?) – well… anyway. There are a number of ways to do this, photoshop, I understand has support for doing this and it’s possible under linux as well with the Gimp.


There’s a good overview on the concept here (hdr for Panoramas) and there’s a gimp.org tutorial on blending exposures.

Now, all I have to do is put the camera on a tripod and try out the “burst mode” on the new camera that does 3 different exposure settings in quick (0.5 second) succession and I’m going to give it a try. By the way – if you’re having a hard time seeing the difference in the top and bottom pictures in the gimp tutorial – look at the blue sky under the arch. It really seems that this can give some beautiful results.
