The shots below are from my recent tests of the Sony Gamma Curves for the F900/3
They were all shot during a kitchen commercial, hence the test subject which does include a fair range of tones :-)
Allclips are uncorrected in any way other than the the two which I have indicated, one was graded on Pogle by Gary at Red to match the complete sequence, the other by me in Combustion, there's a bit of highlight glow added to the one I did.
They were all shot on preset colour balance with no alteration of exposure between the various settings.
Lighting was a 10Kw Fresnel through a 12 * 12 silk with a poly bounce fill.
Click on any of the stills to run a Quicktime of that setting.
