Custom Shooting Mode: Selecting a Scene File
When in Custom(709) Shooting Mode, there are four preset Scenes ( looks) to
choose from: Still, Standard, ITU 709 and S-Cinetone.
S-Cinetone is a new gamma curve and color matrix based on the look of Sony's
Venice cinema camera. The look is similar to shooting Slog 3 with the s709 LUT
applied.
S-Cinetone is the best preset choice because it has the most highlight
information. Exposed optimally, it will provide 11 stops of dynamic range. This
means that one image can have details in the shadows and the highlights of the
image, a relatively new development in video imaging.
In terms of dynamic range, S-Cinetone sits between the standard Rec.709 Scenes
(6 stops) and shooting Slog 3 (15 stops) in Cine EI mode.
The FX line of cameras and the A7sIII and Alpha 1 have the S-Cinetone scene.
