Linear Workflow settings not sticking

[rjw]

Hi,

I've been experimenting with Linear workflow. I ran through http://throb.net/site_main/LinearWorkflow.html
Whenever I set Colour Correction in the frame buffer and reload the file the settings don't stick. I also noticed they don't stick when using BB.
I'm probably missing something here, I did a search but no joy.

I'd be grateful if someone could take 5 mins and explain.
Also I assume Bitmap File (in preferences) should be at 2.2 as well as Display?

Thanks,
Richard

color correct in frame buffer isnt "burned" in the image.
go trough the topic that Gijs started here about that, that will explain more I think.

Basicly, you only correct the FB to see the rendering in linear, the trick is that you attach a gamma correction at the end of your production line, in PS or after effects for example.

You can bypass this by using the gamma color correction in the vray option and set the bright muliplier @ 1/gamma: 0.4545 in most cases.
but this this is semi linear cause by doing this you're not fully in linear space anymore.

I know, quite confusing this all, but once you "click" you know it was worth all the brain punishment..

good luck,
Bart

cheers Bart,
I'll check that out for sure.

This is a misleading statement - most of us are using gamma correction and Linear values are calculated as it's processed. In fact, it gives you what some may argue as better results. A correction curve is just as accurate/inaccurate. They both have their strengths and weaknesses.
