New free G-LOG (S-LOGish) Picture Profiles for the SONY FS100 Version 1.0

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 achieved 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 quite pleasing. Remember, that this are not profiles for shooting “right out of the box”. They both need color grading in post to make them look right.

Okay gentlemen, the cat comes out of the bag:

G-Log comes in two flavors

G-LOG A: Looks deep into shadows

G-LOG B: Is a bit more on the conservative side.

Black Level: +15
Gamma Standard
Black Gamma: High, +7
Knee: 102,5, -1
Color Mode: Standard, +8
Color Level -5
Color Phase -7
Color Depth: R-1, G+2, B-3, C+5, M+1, Y+6
WB-Shift: LB-6, CC-5

Make sure you set your highlights between 85 and 90 IRE on G-LOG A.

Black Level: +11
Gamma Cinematone1
Black Gamma: High, +7
Knee: 75, -3
Color Mode: Standard, +8
Color Level -5
Color Phase -7
Color Depth: R-1, G+2, B-3, C+5, M+1, Y+3
WB-Shift: LB-7, CC+1

Some examples for comparsion:

Since it´s late here and I don’t have sunlight at hand I use my 45 Watt incandescent desk lamp and my monitor for lighting.
I did a WB on my face before recording.

All shot @ 0dp f 1.4 except G-LOG A, that was set to 2f 2.8 (to bright otherwise).

1. No PP at all

2. AbelCine DSLR PP

3. GlenColor1

4. Glencolor2

5. AbelCine Varicam

6. G-LOG A

7. G-LOG B

8. G-LOG A with gain and shadows adjusted in post.

Once those pics are uploaded here in the blog, they way too saturadted, redish and contrasty.

Since every browser seems to handle color different, here is the TIFF download link:

P.S. There is an updated, more neutral (less greenish) version of GlenColor 1 and GlenColor2 aviable:


There is a newer version of G-LOG here

  1. LOL, Ich bin doch auch in Deutschland Amin 🙂

    Im übrigen, Kompliment nochmal für Daimonion. Ich hab auf eurem Blog (DLR-RIG) ja schon was dazu geschrieben.

  2. Hi Frank, Thanks for sharing. The PP’s look great. One question, in your examples of G-Log A and G-Log B is the camera set at two different gain levels? The noise looks different in each and looks cleaner in G-Log B. I also noticed the depth of field looks shallower in B which made me think that maybe the image is cleaner because the gain is down less. Thanks! Tony

    1. Thanks! What zebra settings are you using and what are you shooting for for good skin tones using G-Log A? Any particular LUT you like to apply?

  3. Cool, why did you push the detail all the way down? What will that effect in the image mainly?

    1. Because the Sony tends to over sharpen things. By dialing it down, you take a bit of the “digital” out of it.

  4. would it be possible for you to talk about you went about setting the exposure when using your profiles? Thanks.

  5. Thank you, I have just been searching for information about this subject for a long time and yours is the best I’ve came upon till now. However, what in regards to the conclusion? Are you positive in regards to the source?|What i do not realize is in reality how you are now not actually much more neatly-appreciated than you may be right now. You are so intelligent.
