I've never tried to reproduce this, but I can tell you the reason for the 'odd' color. When color film was first made commercially, it had nowhere near the rez it has today. Basically, every color was jammed into a very narrow-range emulsion. Add to that the fact that the faithfulness of the color reproduction was dodgy, and every batch of emulsion was different, and you got what you got. Photos were indeed unique, since you could never be sure of reproducing the same thing with a roll of film from another batch. When I started selling cameras in the 70s, Kodak used to give a code number to each batch, and professional photographers would buy 10 or 20 rolls to test a batch, then if they liked it, purchase huge quantities of that batch and store it. That way, they knew that for the next year or so, they would know what their results were going to look like. All of which may be fascinating, but doesn't help you in the least. Still, cutting down the color rez may be a good start. mac
