ARRI's logarithmic encoding gamma optimized for ALEXA cameras' sensor characteristics.
Definition
Log-C is ARRI's proprietary logarithmic gamma curve, developed for maximum image quality and optimal utilization of the ALEXA sensor's dynamic range.
Practical Application
Log-C is the de facto standard for high-end film production. The look serves as a reference for other manufacturers. The curve is used in conjunction with AWG (ARRI Wide Gamut).
Technical Details
Log-C3: For ALEXA Classic, Mini, SXT, LF. Log-C4: For ALEXA 35 with extended dynamic range. Middle Grey at 400 (Log-C3) or scaled differently for Log-C4. ARRI provides official LUTs.
