Gamma change in SL
Gamma 2.2.
The default gamma has been changed from 1.8 to 2.2 to better serve the color needs of digital content producers and consumers.
From apple site – seeing we have been 1.8 for a million years what is the fallout going to be for grading you think ? Seeing that PC have always been 2.2 …

I gather from a couple of developers, and a couple of comments from RED staff that Snow Leopard and QT X have fixed the gamma inconsistencies that have plagued Mac users for years. If this is the case (and I’ll find out next week I suppose) I welcome it.

Yeah, I’m wondering about this myself. Doesn’t the current FCP compensate for Mac 1.8 gamma in its video windows for color accuracy (canvas and viewer)? If I shift my gamma in 10.5, the gamma in the video windows in FCP look shifted to me as well.
Will the gamma of the video windows in FCP be shifted in Snow Leopard as well? I wonder if Apple will need to roll out an update to each of its Final Cut programs for Snow Leopard, or if Snow Leopard is FCP aware, or FCP is Snow Leopard aware. I’m very curious.

Thank … You … God!
Honestly, I’m really looking forward to Grand Central and Open CL, but if they can fix the gamma issues of Quicktime then I’ll be thrilled. That would be much more useful in and of itself than any of the updates to FCP 7. I’m so tired of authoring in 1.8 w/ gamma compensation, exporting w/ gamma correction, and then verifying that the corrections are correct for rec.709 vs. H.264 on QT Mac vs. QT Windows. I’ve been running my right monitor at 2.2 to verify how images look after editing in Photoshop, and videos after export from FCP. But even then I see a great difference between images on that 2.2 monitor when viewed in OS X vs. viewed on that monitor in Windows via Fusion.

After upgrading my system to SL, the movies i exporte from FCP 6, seem to become much lighter in their gamma value. The gamma in the viewer and canvas looked darker, but the exported QT movies seemed to be unusually light. i could not find a fix for this.
Yesterday i upgraded to FCS 3 and FCP 7 now display my FCP 6 projects much lighter in the viewer and canvas than before!

SL changed the gamma settings the computer displays to conform to standard PC settings. Your output on your external monitor should remain the same however.
