Gavin Greenwalt Posted June 21, 2007 Share Posted June 21, 2007 (edited) Is there a "standard" LUT to correct for the filmstream cast in post or is it pretty shot specific? Maybe a green gamma/lift/gain setting which compensates for color shift? Edited June 21, 2007 by Gavin Greenwalt Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted June 21, 2007 Premium Member Share Posted June 21, 2007 There is, but it depends on a lot of other things. Most significantly, you need to know whether you want to anti-log it at the same time, depending what else you're going to be doing with it. Also depends what format you want it in.

Michael Collier Posted June 21, 2007 Share Posted June 21, 2007 There are fast LUTs avalible for whiteballance. Common ones would be daylight and tungsten (you'd probably use tungsten exclusivley unless you don't use an 85b outside.) from there you can add your custom look to it. All light being the same, those should do what your looking to do (remove the green and make it 'normal') Link to comment Share on other sites More sharing options...

Ditto the LUT on the HDlink from Blackmagic (as of 6 months ago) Mike Brennan Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted July 27, 2007 Premium Member Share Posted July 27, 2007 Rubbish in what way? Phil Link to comment Share on other sites More sharing options...
Gary McClurg Posted August 2, 2007 Share Posted August 2, 2007 (edited) Rubbish in what way? Phil Same here... I might be working a film that shot Viper... then coming on board to do a week of re-shooting, and then post... of course I don't know if they shot film stream or video stream... but if they did video... this is something I'd like to know as well.... my guess is they did video... for a reason that I can't go into...

Maarten Treurniet Posted August 27, 2007 Share Posted August 27, 2007 You can download a .txt lut that will do the anti-log from 10 bits to 12-bits linear on the thomson site. Then again what do you do with 12-bits linear since there is for example no Quicktime codec that does 12 bit RGB 4:4:4... see the attached pdf.
