Looks, LUTs and Live Grading the ALEXA

Looks, LUTs and Live Grading the ALEXA:

When Arri released the SUP 4.0 firmware for the ALEXA, they also added the ability to create color ‘Looks’ to load into the camera. These Look files are similar to scene files found in other cameras, but they aren’t burned into the Log C recording of the camera. Instead, they can be used in post by converting them to LUTs using Arri’s LUT Generator. These looks then travel as metadata with the clips recorded (through the XML file). Look files can be created by saving a still from the camera and loading it into the Arri Look Creator, which can then modify the still and output a look. A company called Pomfort, based out of Munich, was actually the first to work with Arri Looks. Their software, Silverstack SET, manages data on set and allows the manipulating of Arri Looks before sending them into a NLE or Color Grading suite. Silverstack SET is a fantastic tool for working with ALEXA material in general, and now Pomfort has come up with a new piece of software to take the process of Look creation a step further.
