My shutter jammed mid-wedding at 2:15pm and a bent paperclip got me through the reception
Was shooting a wedding at the Franklin Park Conservatory here in Columbus when my old film SLR shutter just locked up solid on frame 21 of 36. I popped the bottom plate off in the coat room, found the little curtain blade had jumped its track, and nudged it back with a flattened paperclip and a tiny drop of lighter fluid. It ran clean for the rest of the reception, but I still don't trust that body. Anyone else keep a beater camera as a backup, or do you just carry spare parts and hope?
That paperclip fix is solid, but here is the thing most people miss: lighter fluid leaves a thin film that attracts dust, and that grit is what makes the blade jump the track in the first place. I would flush it out with plain naptha when you get home, then put one tiny drop of watch oil on the rail, not the blade. The real move is to run two identical bodies so muscle memory stays the same when one dies.
