[HDR-photo] jpeg exposure adjustment

[Otto Feiler]

Hello Dieter,

Yes, I would like to apply Tone Mapping to some older photos that I took 
that were not exposed properly. I'm hoping to "save" some of them. They 
aren't for public viewing, just some vacation shots that I would like to 
improve. I will try converting them to the 16 bit TIF as you suggested.

Thanks for the help,
Otto...
