Yes, because like I said, we'd only planned on doing the Lomochrome Purple shoot and I only had one roll of that. I wasn't to know when trying to ready the film for loading that the leader had been stuck down with industrial strength tape.Wow, you only bring one roll of film to a shoot where a model comes from out-of-town?
I know that I sometimes take too much precaution, but I bring more sets of batteries than that.
Ok, I was using a Pentax 645NII. Once the film back has been loaded with film then the back inserted into the camera, it's just a case of pressing the shutter button to advance the film to the first frame, whereby the figure 1 appears on the LCD display. As no number appeared after 4 attempts, I assumed the camera never recognised I'd loaded the film and I put that down to the torn leader. When I removed the film back, the film had advanced, so I'm guessing I could've taken photos on it, but I wasn't to know that until I'd opened the back, by which time it was obviously too late.Which model of medium format camera were you using and how does it determine when the film has advanced from the alignment arrows to the first frame?
Do you know whether the film advanced at all? Was it not possible to rewind the film before removing the insert?
I'm wondering if the thickness of the paper backing could've been an issue. Maybe too thin?
I have the 645N (not exactly the same as the OP, but only a couple of differences). You put the roll on the supply side and pull the paper out and hook it into the slot on the take-up side then turn a wheel to pull some over. When the "start" with the arrows on the paper is lined up with the mark on the holder, you put it in the camera. Turn on the camera, set the ISO, press the shutter once - it should turn the takeup reel a measured amount that gets it to #1. Mine (I just checked) are all within a few mm of being at the same spot.I'm curious how the Pentax 645 determines when the first frame is ready.
I'm not sure how it determines the first frame either. All I do is spool the leader as normal on any MF system, attach the insert into the camera then press the shutter button, whereupon it winds to the first frame and stops, then indicates the number 1 on the LCD display. As I said in my op, it was making all the right noises when I loaded the Purple film and pressed the shutter button, it just never displayed any frame number, instead just remaining blank. With hindsight, I probably could've taken photos with it, I just didn't want to risk going through with a whole shoot and put the film in for development, only to end up with 15 blank frames. Also, was worried about buggering up my camera. Still, fingers crossed all goes well with the new film.Nice customer service.
I'm really curious why the first frame wasn't detected. With four attempts and obvious advancement of the film, I am mystified.

Will definitely take along a roll of my trusty Portra 160 on my next shoot with the Purple, just in caseWord to the wise.If you are planning to go out and use that replacement film on another shoot, buy and take along at least one backup roll, or at least take along another roll of film.
Yes, was definitely lined up on the 'start' part when I attached the film insert into the camera body, so what was left of the torn leader (refer back to my op for details) was definitely wound fully onto the take up spool.I have the 645N (not exactly the same as the OP, but only a couple of differences). You put the roll on the supply side and pull the paper out and hook it into the slot on the take-up side then turn a wheel to pull some over.

Turn on the camera, set the ISO, press the shutter once - it should turn the takeup reel a measured amount that gets it to #1. Mine (I just checked) are all within a few mm of being at the same spot.
My guess for the OP is that the sticky part remaining from the wrapper may have been touching something and kept it from being able to pull the film? Though that part should have been securely on the take-up reel from you turning it to get the "start" spot lined up.
Yes, shot a roll of Portra 160 yesterday with no problem whatsoever.Have you tried a roll of the same film types as when you last successfully shot with that camera? Something is not adding up if we look to the film as the cause, and everything as you have described indicates that maybe it's your camera. It could have been the roll is the root of the problem, but nothing more than gunk obstructing/effecting whatever mechanism your camera uses to determine there is film loaded since you even confirmed the leader was wound on the take-up spool up to the start position (pretty secure at that point).
every attempt thereafter to wind the film on saw the leader jumping out of the spool. In the end I had to take the spool out of the film back and manually roll the film a couple of turns to make sure it had 'taken'. Never had this problem before in all the years I've been using medium format.
I wasn't being optimistic or stupid, we (myself and the model) had only the intention of shooting with the Purple that day.I always stick the leader to the spool with a bit of tape to be sure. I've never trusted the slippery paper and smooth spool to hold tightly on it's own.
That first roll sounds like it had been kept somewhere damp for a while and glued itself to itself.
And only taking one roll of film to a shoot? There's being optimistic and then there's being plain daft. What if you'd finished the roll and then found an amazing new location to shoot or the light changed for the better etc. etc.?
Thanks, the rubber bands is a good tip, will keep a few in my camera bag from now on.This is why I stick with film from major manufacturers (and even thats not safe with kodaks on going paper issue)
With 120, I always bring rubber bands incase i ruin the lick to stick strips - especially when in using expired films
I don't understand how the camera didn't recognise that first Purple film either. As I explained, the leader was torn along its length, not widthways, so although it ended up not being as wide as normal leader, the length was unaffected and I still lined it up with the start arrow before inserting the film holder and winding it on to frame 1. For some reason, though, the camera simply didn't recognise there was a film in it as no number appeared in the LCD display, despite 3 or 4 more presses of the shutter and the film audibly winding on.I have a P645N not Nii but I think the insert and wind mechanism are the same. It struck me as I read the thread that if the paper leader is the problem then couldn't that problem part be cut off and a new pointed leader be cut with scissors. This would give less backing paper before the film is reached but as the loading relies on the line being opposite the start position I cannot see how a slightly shorter leader would make any difference to the camera's recognition of correct position for frame 1, otherwise if the leader somehow got damaged or slightly torn then making a new leader would effectively ruin the use of the film, wouldn't it?
