Is Brightness/contrast 32-bit clean? I would presume so. Brightness has the virtue of moving all values equally, no companding.

Hi all,
I’m currently working on a project where frames are supplied as multichannel exrs. I’m working in 32bit float, linear space. The z-depth pass has raw values in it which are huge, I am normalising it in a precomp so I can see it, and tint it for fog/atmos effects. Currently I’m using the exposure effect to bring the values down into visible range, but as the exposure plugin has a limit of 10 stops sometimes I’m having to use 2 copies. Once I can see the image I use the levels effect to fine tune the blacks / whites.
I’m wondering if there’s a better tool. I know AE is a bit lacking when it comes to 32 bit support, so is there a better way to bring these massive numbers down into a 0-1 range? Or is exposure / levels the best we’ve got to work with?

PS. It’s not an option to change the way the z pass is rendered in 3D.
