I was able to find (almost) no information on this online, I guess I'm the only one still using CS4 (and CS3...).
Red's CS4 plug-in supports up to build 18, we're in build 30 now. Shots that I recently acquired (at 3200K) and imported are very yellow. If I set the color space to REDspace and push the blues to around 5.00 I get close to the look but there's still too much yellow (even with blue at 10.0).
All I can find is info about how CS5 supports the new color science. I get that, but hoped to get a finite answer if CS3/4 are useless for new footage, before I invest in alternative workflows.
Yeah seriously- if this is not a hobby keeping up with the current version of your main editing software is part of the built-in cost of doing business. You can't expect manufacturers to continue to support outdated versions of software. Most of them haven't the time or the money to go back that far.
