I'm actually surprised that no-one has brought this up yet!
I have been shooting HDR for a wee while now and would like to share the results I have had.
HDR images are basically made up of several differently exposed shots of the same scene. I normally start by underexposing by 2 stops at a time, and work my way up. The following image was made up of 4 images as shown below.
The software program PHOTOMATIX combined the images and picked the best exposures from each one.
It then makes a tone map and produces what you see above.
Anyone else been shooting HDR?
