LUTs, or lookup tables, apply an instant ‘look’ to your photos by remapping the existing colours on to new ones.

LUT is short for Look Up Table. It's a kind of conversion profile that 'remaps' the luminance and colour values in an image on to new values. LUTs are widely used in cinematography to create a certain 'look' and they have now captured the attention of software publishers.
