Digitized film images originating from a datacine conversion
process are high-resolution scans that preserve much of a film's
resolution and colour depth. In Flame, a lookup table (LUT) is
the primary colour management tool available to deal with
different colour spaces. A LUT is an ASCII file used to map
pixels or pixel components from one colour to another. To
display logarithmic film scans properly, such as Cineon files in
the linear colour space native to Flame, you can work with
monitor, display, and image conversion LUTs. You can use one of
two kinds of LUTs: 1D LUTs and 3D LUTs. Digital film scans often
consist of logarithmic data rather than linear data. Linear data
maps the luma range in equal intervals from black to white.
Logarithmic data allows for more subtlety in the lower luma
ranges of an image. In Flame, you can work with either
logarithmic or linear data. When you want to work with linear
data, you can use an image conversion LUT on input to convert
the logarithmic data to linear data. Since
