Using CS2 .. You can open the picture ... and see the Shadow/Highlite tool

This will let you change the "Too Dark'" (underexposed) Background ..
or the "Too Bright" (overexposed) whites... more or less independently.

I increased the dark background in your picture, but going too far, and it will get noisy ...
So I stayed a little short .. keeping the foreground the primary objective.

ChuckE's version looks pretty good, maybe you want to play with this tool in CS2 and touch it up some more.
It seems that I use this CS2 Shadow/Highlite tool very frequently on digital shots.

You might be surprised how well it prints, Maybe we've got you too scared.
