GFILM
Made for A7rII, should work on A7s, A7sII, A6300, A6500  EDIT: While it will work on all these cameras, some have been reporting subpar results on the origional a7s due to its slightly different color science. I've only tested myself on the A7r II, results may very slightly on other cameras.

I've been trying to give the A7r II a look similar to "Film" on the blackmagic Ursa Mini 4.6K. The need arose because I am shooting with the two camera side by side and need to edit them together.

Had a couple goals with this:
- Get away from the "Magenta" look
- Be able to match with BM "Film" in post
- A flat profile that doesn't break when grading like S-log sometimes does, is easier to shoot with, and can get a get a great look with a simple color wheel adjustment.
- Don't clip any color channel

Let me know what you guys think!


Black Level: 0
Gamma: S-Log2
Black Gamma 
- Range: Middle
- Level: 0
Knee: Manual  (It blows my mind this is left on Auto by default, it controls how the highlights behave)
- point: 77.5%
- slope: +3
Color Mode: Pro
Saturation: +3
Color Phase: -4
Color Depth: (Wish they would let this be adjusted for highlights/midtones/blacks independently)
- R: +5
- G: +7
- B: +3
- C: +2
- M: -2
- Y: +2
Detail: -7
- Mode: Manual
- V/H Balance: 0
- B&W Balance: Type5
- Limit: 3
- Crispening: 3
- Hi-Light Detail: 0

Couple notes on shooting with this:

-Always overexpose by at least one stop to get a clean image.
-Set WB manually, do not leave on Auto
-Shoot at the native ISO of your camera

UPDATE:
I've created this correction LUT for viewing on external monitors and to provide a quick correction in post. Keep in mind that this is a correction LUT, and does not replace actual grading, it's just meant to give you a good base. I typically apply this then raise the highlights/exposure further.

Please feel free to test and give feedback!

(This shot above was underexposed, resulting in noisier blacks)
