Film looks Ektar 100, Gold 200, Pro 400H, Portra 400 and Vision3 250D
(firmware film simulation) and Vision3 250D (film library, built in):

Adapted from film looks rendered by spektrafilm v0.3.4 by Andrea Volpato
(film modeling powered by spektrafilm, https://github.com/andreavolpato/spektrafilm),
as fitted to GR III camera parameters by idontknownihil
(https://github.com/idontknownihil/gr3-film-mods).
Changes by GRLife: Q13/int16 rounding, 33-knot storage of the fifth film's curves,
and packing as firmware patch bytes and film library data.
