[Sidefx-houdini-list] Film at 16 bit

I was hoping to hit you film guys and gals up for just a bit more  
advice about rendering for 2k film.

Just wondering, of the available quantization option on the mantra  
output drive,
if there is any one that is considered a "standard"?? .....  or if it  
varies widely depending on the shot, production. etc.

I re-read Jeff's old school blog on the subject which makes it pretty  
clear that it needs
to be at least 16 bit. I'm just wondering what might be the best  
choice to consider.
-16 bit integer
-16 bit float
- 32 bit float

Background on this particular shot we're producing is
1. It will be rendered in mantra, composited and output from COPs
2. There is no live action, not many textures.
3. It's very heavy on volumetric light ( bursts and light beams, that  
sort of thing) lot's of blurring etc at the COP level.

While I'm at it, I guess I'll ask about preferred image format. I was  
assuming 16 bit tiff, but not sure if that's best

Anyway, sorry if these are somewhat basic questions but would very  
much appreciate any thought from those who have
more experience with film.

Thanks as always,
