; Serge Mankovski B/W Film Simulation
;
; Copyright Serge Mankovski (sevato@mankovski.com)
; Toronto, Ontario, 2007
;
; Version 1.1 March 30, 2007
;
; Converts selected layer into Black and White using channel mixer
; Uses channel presets found on Internet. I am not sure about the origin of these
; settings and I do not know if they really produce result resembling tonal qualities of
; the film, but it produces nice looking B/W and it is a useful way to convert to black and white
;
; Change Log:
; Version 1.1
; - added IR film simulation
; - added color filters applied before b/w conversion
; - added saturation option
; - Gimp 2.3.15+ support
;
; Version 1.1.1 Various fixes by Ari Pollak - thanks!
