I haven't had a bit of trouble loading 4x5 holders, other than dust which I am slowly conquering. But when it comes time to unload them, I'm not sure what to do. I don't want to touch the emulsion because I have gotten fingerprints on the negatives that way. Even if I was willing to try to slide the film out, there seems to be a ridge there to prevent the film from sliding straight out. Yet it's really hard to pick the end of the film up with a fingernail, and then in order to grab it to pull it out, I have to bow it up a lot to fit one of my fat fingers underneath it, sometimes one side will pop out of the groove halfway, and I end up yanking the thing out of there rather than sliding it out of the groove. tips?
