I have made a new version of my image manipulation program
HCR-Edit is a windows program for post processing images and has the
capability to deal with images of more than 8 bit color depth per
channel. New features in this version are:
* support for reading and writing HDR high dynamic range images.
* support for reading raw float data.
* support for writing binary and ASCII float data.
* exposure adjustments.
* normalizing function.
* various other improvements and fixes.

Very nice, Christoph.
Combining the Exposure and Curves settings allows your program to have more
control over HDR images than even HDR shop does!
Requests:
How about an Exposure slider? Also an undo feature would be nice
in the curves editor :)
Potential problem:
When I first open the program, and load an HDR image (the Exposure
contol is checked), it appears totally black, even though Exposure and Gain
are both at 1.000. I have to set the Exposure and Gain to 10.000, then back
to 1.000 to get an image.
Best Regards!

Well, curves do only work in a limited range of values so they are not
suited for HDR images. Therefore saving in a high dynamic range format
does not use the curves (and levels) adjustments.

The adjustment of all values is somewhat limited right now, i consider a
solution for all value adjustment fields that would allow easier
modification of values.
