What does a boy when alone at home? Right, he plays with his toys. I was musing over S-LOG for quite a while and was wondering if something similar – or at least S-LOGish – can be achived via the PP settings. So I looked at waveforms of S-LOG files out of the F3. I tried to match them – as close as possible with the FS100. Of course that isn´t real S-LOG but if handled right, it can be quiete pleasing. Well maybe I should call it G-Log with a “G” like in Glencairn ;-)
Just a little teaser for the moment (with my own silly face)
Those JPEGs got converted to sRGB so they look a bit different – actually darker – as on a proper calibrated wide gamut monitor, but you get the idea.

When I started to explore this, I wasn´t sure how those settings would behave in 8 bit space at a long GOP codec. So I recorded in the camera and uncompressed on a BlackMagic Deck at the same time. The differences are almost not there. Uncompressed is a hair sharper and a bit nicer in blurry (out of focus) areas, but nothing to write home about. The AVCHD codec of the FS100 holds up to grading the same way the uncompressed material does (much to my surprice) and refuses to fall apart. At least as long you are in a 32 bit floating point space.
I continue working on this and do some further tests with highlights and skin tones.
There is more to come, watch this space!
Okay, here comes a little update.
This was shot with GlenColor1 PP for outdoor use.
here the same clip after grading
If you look at the scopes, you ca see what G-LOG does. ´it´s not really an S-LOG, but it gets a different distribution of values, that are quite handy in post.
There is one strange thing, that I don´t understand yet. If you look at the scopes from the first shot on GlenColor1 PP, there are those empty lines, in the luma and YUV parade.
Looks like there is information missing. Whereby the information in the G-LOG shots seems to be more complete and dense.
