I loaded my Hasselblad with some Ilford Delta 400. As it turned out, I didn’t load it very well. The winder became a little reluctant about a third of the way through the roll.
Then, when I was loading the film onto the spiral after shooting it, I couldn’t get it aligned correctly.
End result: three or four wrecked frames.
I subsequently Googled ‘Loading a 501CM correctly’ and discovered that I’d been missing out a crucial step: it appears that you have to slide the film leader under a lip at the top of the magazine, which I didn’t know.
Needless to say, the ruined frames were some of the better ones on this particular roll.
Ignorance was the cause of my errors: I hadn’t taken the time to learn how to load the film into the camera properly. I’d also forgotten how to load film onto a spiral correctly. The cost was a couple of lost photographs. I can always go back and re-take the photographs but they’ll not be quite the same. Some lessons are learned the hard way. It seems age is no protection.
