Is there anyway to designate the exposed negative, so you know which shot it was. As in, if two or more shots where made of the same scene, at a different exposure. Background: Just got a MF Graftmatic with 6 septums. With my standard MF film holders, we have notched the film holder flap, with a notch code to know after developing, what shot it was. They show up as a small dark V, or V's off the end of the image. Has someone come up with a way to do this with the MF Graftmatic, the metal film holder edge on these are very narrow.
