OK, I don't have Photoshop, so I read a few articles on the Web about using the Exposure adjustment in Photoshop to get an understanding of how it works.
It's an intriguing adjustment, and I have a request to make it even more powerful in PhotoLine --
Implement the Exposure adjustment as a means of adjusting specific tonal ranges (either 11 or 9 ranges of the Zone System) in the image. I think the value adjustments of the sliders would be best if applied to the "L" channel in the Lab colour space so that colours would not be changed.
For example, the bottom of the dialog would have 11 (or 9) buttons to choose the specific tonal range(s) to affect:

The adjustment sliders would apply the values only within the selected Zone.
I think this would be an exciting addition to PL. It would be a simple and elegant means of bringing the concepts of the Zone System to digital photography. Ansel Adams would be smiling!
Having that type of Exposure adjustment would also eliminate the need for various complicated procedures of creating Luminance Masks for specific tonal ranges. This would greatly simplify working with images, I think.
