Ok, so I was approved (because of honor student status) to use 120 film and a 645 camera for my photo classes. Problem is, someone at the University of Memphis has apparently disappeared with all of the 645 Negative Carriers. I have looked online and found them to be quite expensive (70.00 used). Does anyone know of an inexpensive source for one or maybe even have one lying around they no longer use? The enlargers we have at the college are Omega and we use glassless sandwich carriers. Any help would be appreciated as right now I am using two pieces of foamcore with taped edges and getting some really gnarly light falloff when I am printing. Thanks.
