Shooting Modes: Custom and Cine EI
Cine EI mode is common to all Sony cinema cameras.
Cine EI mode is for shooting Slog 3. Shooting in Slog 3 provides an increase in
the luminance range of the exposure (15 stops of dynamic range). It has more
dynamic range than shooting in Custom shooting mode with the S-Cinetone
Scene.
When working in Cine EI mode you can apply a LUT to the viewfinder and on
the SDI/HDMI outputs. Working with a LUT makes exposing Slog 3 much
easier than shooting Slog with other non-cinema Sony cameras. Slog 3 images
require more work in postproduction to normalize and correct, but you can
also use a LUT for correction.
Cine EI mode can also be used when recording a RAW file to an external
recorder.
