tiff, openexr,radiance,photoshop sequence psd, all support 32bpc/float.
You can buy video codecs with 32bpc too.
I think openexr has the smallest size and psd has the largest.
Openexr and tiff are the most compatible with software.
The only issue I had was openexr shifting subtle pixel values which is kind of hilarious because ILM created it. I went from 0,16,49 to 0,15,50 to 1,16,50 in only 3 generations. ack!
I personally only use tiff with lzw compression off.
Don’t forget that dynamic link works in 32bpc.
