What is a Look Up Table (LUT), Anyway?
There are a lot of great tools out for grading and finishing. Cineform’s First Light has been out for a while now and Red Giant’s LUT Buddy was just released. Technicolor also released their CineStyle profile for Canon DSLRs and their documentation talks about using the included Look Up Table (LUT) in the post processing of your footage. The new Sony F3 will soon have a firmware upgrade that enables an uncompressed 4:4:4 S-LOG mode that utilizes LUTs. So, what exactly is a LUT?
