IMHO, both the approach suggested by rich2005 and Ofnuts are about trying to adjust the luminosity, in order to even out the exposure on both sides.
The results obtained however, while balancing the exposure evenly, leave the right side of the image (the originally darker side) with a slightly more 'reddish' hue.
Maybe it's just my eyes...
So I tried to find a way to try to reduce this contrast in tone between the sides, and for that I used a mask to separate the sides, and I applied a curve to try to correct the difference in exposure and tone.
You didn't really try my method. I use two layers with a mask, the right side is left untouched. But it's true that there is a slight color shift (or at least desaturation) on the left, but this would require processing each color channel separately.
