What is a LUT?
A LUT is a “Look Up Table” and can be used in many ways, including changing the color or brightness of a video image, and to convert from a Log image to another type, such as a Rec. 709 image.
Throughout the world, the color standard used for broadcast is “Recommendation 709”, commonly known as “Rec. 709”. But, Rec. 709 has a limited dynamic range, just over 6 stops. Most modern cameras can record higher dynamic range, far greater that 6 stops. For film work, this higher dynamic range needs to be preserved, and the image may be recorded using a Logarithmic encoding scheme, thus the term “Log” footage.
Log images are low in contrast (typically) and can look “milky”. A “Log to Rec.709” LUT may be used to create normal Rec. 709 image with normal contrast for monitoring while recording the higher dynamic range images for post. In many cases, a Director of Photography or Cinematographer will create a special “look” for a project. This “Look” may be one with highly saturated colors or dark images for another type of project. Custom 3D LUT’s may be used to create above “looks”, as well as may other types of “looks”.
The Odyssey7Q, Odyssey7Q+ and Apollo allow you to use the 25 Preset LUT’s that we provide, while providing you with the ability to load approximately 140 more custom 3D LUT’s for use as needed.
