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!
George Pantazopoulos

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.

I think i have found the problem - will be fixed in next version.
