; Author statement:
;
; You can find more about ISO Noise Reduction at
; http://www.gimpguru.org/Tutorials/ReducingCCDNoise/
; but this script uses a different method (masking the edges and then
; blurring the individual color channels or the lumimance channel only).

; - Changelog -
; 02.11.2007 - fixed for gimp 2.4 by Alexia Death. Lab
; layer order for recompose has inversed between versions
; This script WILL NOT work right for 2.2
