What is a LUT and a HALD?

A Look-Up Table (LUT) is a file containing math instructions to replace a color by another one.
This process is done pixel by pixel, that gives a very high accuracy.

A HALD is a 3D LUT converted into 2D image as JPG or PNG file.
The HALD is a pattern containing all color values (pixels) for a specific size of grid.
Bigger is the grid, better color accuracy is the output generated LUT.
