Curves/Specail Problem

I have some digital images taken in the interior of a renovated
theater that I need to improve as best I can. Taken with flash,
indoors, in an area that was almost dark.
I've played around with Curves and can improve them slightly, but
would like suggestions of how to go about it better. This is just one
of a series of images, so I'm looking for "how to" and not "do it for
me".

In article <lukai2l0sbbe0fn0t0kk5eh1qp5s9t35g6@4ax.com>,
Start with Levels to set the white and dark points, then move to Curves.
The dark areas of those images are degraded very badly because of JPEG
compression; lightening the image is going to make the severe
degradation more noticeable.

Unfortunately, there does not appear to be enough detail in the specific
image you provide to recover a good quality image - any attempt to pull
detail out of the shadows results in blocky jpeg artifacts.
Reshooting aside, I think there is still some hope of getting a good quality
image from your originals. One method that can substantially improve the
appearance of underexposed images would be to use Dan Margulis's pseudo
profile technique. This is discussed in detail in his book Professional
Photoshop, which includes an example of the rather amazing recovery of an
underexposed image.
In a nutshell, the technique consists of creating a "false profile" whose
primaries are copied from Adobe RGB or ProPhoto RGB, with a very low gamma
value. Then assign this profile to your image - voila instant brightness
and saturation. Then use curves to fine tune the result, and there are
techniques to deal with the inevitable noise in the shadows..
You may download a pseudo profile at the curvemeister download site:
