[HDR-photo] jpeg exposure adjustment

[Otto Feiler]

Hi Roger,

Forgive me, I'm still new to all of this, and was unaware that I couldn't 
gain anything with this idea. I have some underexposed shots that I would 
like to "help", and thought that perhaps by creating a couple of copies on 
either side of these that it might improve them by tone mapping. 
Unfortunately, I don't own CS3 as it's out of my budget. I only have the 
Elements versions that I mentioned earlier. Perhaps what I really need to do 
is to try to rescue these images through other processes in PSE. However, 
after trying that, the results weren't very good. I guess there are some you 
just can't save.

Thanks for your input,
Otto...
