; FU_photo_fix-overblown.scm
; version 2.8 [gimphelp.org]
; last modified/tested by Paul Sherman
; 02/12/2014 on GIMP-2.8.10
;
; No editing except for menu entry involved -
; Very handy for adjusting and overexposed photo
; without resorting to curves and other tweaking
;
; 10/15/2010 - restricted to RGB to eliminate errors on indexed and gray
; 02/12/2014 - added strength option as well as flatten.
; 02/14/2014 - convert to RGB if needed
; 10/20/2020 - updated to work with GIMP-2.10.20
