| No, I’m not sure what’s going on there. By default it’s not 32 bit, unless you click a checkbox to use a legacy version. Then it has a range of +/- 150, which doesn’t make a dent in these frames. Just for fun I applied 50 copies of the effect all at -150 and still no joy. Shame that a lot of the Channel plugins are still 8 bit only... > On 9 Aug 2018, at 4:21 pm, Timothy Sassoon <AE-List@media-motion.tv> wrote: > > Is Brightness/contrast 32-bit clean? I would presume so. Brightness has the virtue of moving all values equally, no companding. > > Tim > On Aug 8, 2018, 11:16 PM -0700, Chris Zwar <AE-List@media-motion.tv>, wrote: >> 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? >> >> >> -Chris >> >> PS.
