Hey guys, google has given me no luck.

I've always had my film in rolls but have been re-rolling lately and the counter always goes to 36 but blinks because it doesn't know how many actual frames there are.

The problem is I want to shoot 20-24 frames only, but I don't want the camera to keep advancing and risk tearing the film out of the canister. I want it to stop and re-wind at 24. How can I change the "countdown" number to 24?

Yes I know I can make it count up from 1, but that doesn't solve the whole "too much stress on the tape at the end of the roll in the canister" problem.

I can't seem to find it in the manual, but the "36" blinks because it knows it doesn't know how many exposures it actually has, so there must be a way to change that, no?

Thanks guys!

Motorized cameras to my understanding typically have a means to control torque at the end of the film strip.

Don't worry about the camera tearing the film off of the tape. Just be sure the single piece of masking tape goes right around the spool and makes good contact with at least 3/4 inch on both sides of the film.

Are you using 'blank' canisters or reloading ones with DX codes? The DX coding system allows for 20 or 24 exposures to be set - some fiddling might enable a canister to be successfully modified to comply with the DX coding - can't find anything in the Canon custom functions to enable the automatic shooting of shorter rolls.

Does it have custom functions available?

Yes but seemingly not that particular one.

You can make your own DX-coded labels to put on your film canister and thereby select the number of exposures:

I suppose that may need to be the only solution that works.

Thanks Matt, I should have been more clear, I'm re-rolling using NON-reloadable spools that I cut the end as it's sticking out of the spool and I tape bulk film to what is sticking out and re-roll it back in through the felt (not recommended for the faint of heart).

So it's more that the tape might give between the two pieces of film that are basically spliced together with a small amount of tape.

It might never become an issue, but also I don't always look at the frame count and ultimately end up shooting some frames that have already been exposed to light while loading, which is also annoying even if the film doesn't give way.

Thanks for trying to help everyone.

Sorry 'bout that GI.
Rockwell says it gets the frame information directly from the DX label. Exactly 24 or 36.

No worries, yea, looks like I have a lot of scraping and taping to do... 400 ASA / 36 exposures becomes 800 ASA / 24 exposures.

Good times .... have to do this to 20-30 rolls...

Print replacements on a computer label printer?

If you are upcycling old cartridges bulk load only into cartridges that contained 24 exposures then you don't need to make a mess.

I don't own many 24's, I'm not buying ones from others. It's ok, at least this is a solution. Plus now I can also designate ASA 800 which is what I manually change it to each time anyway, so it's a double solution.

My printer doesn't print metal, does yours?

(Edit): that sounded cheeky, it was meant to be funny.
