G-Log Ultimate 1.0 Picture Profile for the Sony FS100

After further trying, to milk out the last bit of the FS100 sensor, I think I finally came up with the “magic formula”.
It holds and rolls highlights better than any of my other profiles, gives more DR than ever and also is the closest you can get to S-Log in a FS100.
If you ever looked as a S-Log or Arri Log waveform or RGB parade you can see that most of the data lives between 20 and 80 IRE.
This is what you get with this PP.

I gave it a test ride today, when I shot a commercial and I can’t hardly belief this came out of my FS100.

Here is some comparisons of what you can expect´ (before and after grading)

Whereby “grading” actually was just lowering the complete luma, till it just touches zero IRE.
So it’s 100% non destructive (unless you don’t stretch the levels) and doesn’t introduce banding and other ugly artifacts.

This was shot on SD card in the FS100 with AVCHD – if you record external, there is even more room to play with.

So here are the G-LOG Ultimate settings:

ZEBRA: set your zebras to 100 and make sure they never show up (unless in lights, chrome or other super bright and shiny things)
BLACK LEVEL: variable – as in G-Log, set your black levels a hair above zero IRE (or until the histogram touches the left side)

DON’T GET CONFUSED WHAT YOU SEE ON THE CAMERA SCREEN, HAVE FAITH, EVERYTHING WILL FALL IN PLACE.

GAMMA: Cinematone2
BLACK GAMMA: High/+7
KNEE: Manual/80%/+1
COLORMODE: Cinematone2/+8
COLOR LEVEL -2
COLOR PHASE -7
COLOR DEPTH: R -3/G +2/B +5/C 0/M 0/Y 0
WB SHIFT: all zero
DETAIL: Level -3/BW Balance Type3/Limit7 everything elese at zero

Here is an indoor example at 2000 ISO – as you can see, the G-Log ultimate also keeps the noise as low as possible.

If you are in Premiere, the “Luma Corrector” gives you the best, non destructive performance.
Just grab the Pedestal slider and lower all the levels till they touch the zero IRE line. Done.

Make sure you dial in the color temperature (WB) manually with the little wheel, don`t do auto or push button (greycard) balance,
since that will screw up your color on the magenta/cyan axis.

Every color cast you might get, by doing this, is easily fixed in post.

I hope you guys have fun with the new PP.
As always, this is work in progress, so check back from time to time, if there is a newer version.

The pictures you see here don’t really reflect the actual quality you can get out of this.
They look much better on a calibrated production monitor. After having them exported, JEPGed and uploaded here
gamma, saturation and contrast changed a bit, so take them with a grain of salt and try the PP yourself, to see what you can actually get.
