Thanks! Here are the two screenshots using the levels adjustment method from my first post. There is some “junk” at the left side of the levels that I removed to get the left and right side aligned between the R, G, and B channels. I didn’t use anything in the picture to come up with the color correction. I just looked at the histogram and slid the left and right sides to just before the ramp ups. I also added adjusting the gamma to show the darker areas are in tact. I over adjusted it, but it can be done less so to bring up the dark areas just a bit.

I will see if I can get similar results by playing around with the curves and other tools you mentioned when I have some more free time. Thanks again!
