Thanks for the tips. It did help. However there is a black and white image below the color. so it's impossible to get saturated colors like a real color photograph. It does work in a limited way. The colorize menu does allow for more flexible color. Does anyone know how to use the alpha layer in colorizing B&W photographs. -- Jack Denman <[email protected]> _______________________________________________ gimp-user-list mailing list List address: [email protected] List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
