Requests: pretty much most of the things that Dubcat has been covering in his thread re tonemapping.
For me I'd like to see reworked tonemapping from the ground up (proper filmic controls). Essentially I'd like DSLR like VFB results, especially with regard to burnouts/black crush and sometimes odd colour saturation. I've mentioned this before but if we could somehow port whatever FStorm is doing with their tonemapping to Corona I would never use FStorm again (well, apart from it's sweet geopattern feature and the way it cleans up DOF).
