NAMEppmflash - brighten a picture up to complete white-out
SYNOPSISppmflash flashfactor [ppmfile]
DESCRIPTIONReads a portable pixmap as input. Increases its brightness by the specified flashfactor up to a total white-out image. The flashfactor may be in the range from 0.0 (original picture's brightness) to 1.0 (full white-out, The Second After).
As pnmgamma does not do the brightness correction in the way I wanted it, this small program was written.
