I realise PM isn't an image editor, but it would be great to have the ability to make some form of limited exposure control. Maybe to be able to go up or down 1/3 stop, or to open the shadows or up saturation a fraction would be useful. I'm sure this must have been requested before?
We do get this request every once in a while. It's not in our current plans. We may reexamine this in the future.
Can I add support for this feature as it would make culling within PM more versatile being able to open up slightly under or over exposed images or just to get a feel for shadow detail.
