I'll have to look at the next roll I develop - maybe there is more room
at the end than I remember. I'm mostly shooting with an *ist film body
and Mz-S these days, so the camera decides when the film is over. But
both bodies let me leave the leader out, so I could pursue the short
leader option for reloading canisters...

Taking as an example my K1000, the distance between where the film
comes
out of the cartridge & the nearest edge of the shutter window is about
1/2 inch.
I think that's about right. I was going to look, but I can't right now
because I have film in the camera.
Plus whatever slack there is from where you're winding the next frame
and only get half a stroke & know to rewind because if you force it
you're either going to break the film off from the cartridge or you're
going to get overlap on your last two frames.
I don't know of any camera that would put an image on that last inch
or
so of the film. I'll bet not exposing that area is even part of the
specification Kodak gave the camera manufacturers many years ago.
... or whoever invented the 35mm film cartridge.

Interesting - wouldn't the minilab lose the last frame by cutting off
the film? In the rolls I develop by hand I get pretty close to the
end
of the spoolm but maybe the cannister is smaller than I think.
I once brought a roll of E-6 to a Walgreens and was upbrided by the
machine operator who told me it would ruin his chemistry... brought
it
to the pro lab instead.

I've got several "reusable" cartridges that turned out to be old
commercial cartridges with a plastic label applied to hide the
original
artwork.
Actually, when I was running the mini-lab I kept several Chinese
commercial C-41 cartridges that had plastic labels over the original
Fuji film artwork (not just re-badged Fuji film because the
underlying
cartridges were originally Fujichrome E-6).
So they can not only be reused for hand reloading, they were
sometimes
reused for commercial reloading.
Also, the way we processed film at the mini-lab left a VERY short
leader
sticking out of the cartridge. If you're careful *NOT* to rewind
that
leader into the cartridge, you don't need to pop the ends off the
cartridge.
Just tape the end of your bulk film to the leader & use it to pull
the
film into the cartridge. Once you've got a couple of turns on
friction
will help to keep it from slipping off if the tape doesn't hold.
But, if you rewind it & lose that leader inside the cartridge, it's
not
long enough to retrieve with a leader extractor.
When I ran the mini-lab we had a big box to throw the old cartridges
into. When it filled up it got taped up & shipped back to Kodak for
recycling. I bet, if you can still find a mini-lab where you are,
you
could ask and they'd let you take something like a gallon zip lock
bag
full of used cartridges away with you. Might even let you pick
through
the box to find the ones the stub leader hasn't been retracted yet.
Probably won't even have to ask "Pretty Please!"
One thing about mini-labs.
You can take the occasional E-6 in and have it cross processed
without
hurting their chemistry and you get some really different negatives.
But, NEVER, EVER take traditional B&W films to a mini-lab. The
average
mini-lab operator drone won't know what it is & they won't know any
better than to send it through the C-41 processor. It can mess up
their
chemistry a little bit (they'll get over it if they even notice),
and it
will definitely EFF UP your film.

Then you are probably the right person to ask this question - can
you
re-use commercial film canisters? I am somewhat embarrassed to
admit
this in a public forum but I just developed 2 rolls of Pro-Max 100.
Just
for the fun of it I tried popping the end of each canister off with
just
my fingers, no can opener. They came off easily and after the film
was
spooled I put the canister, center spool and ends back together.
Both of
them look perfectly serviceable. Did you ever try re-using the
actual
canister? I don't think this would work with Kodak or Fuji
canisters -
the end caps on those seem to be held on tight and a can opener is
needed to get them off - but who knows about other brands, like
UltraFine and Adox etc...
If I can reuse the canisters, which normally sell for about $1
each,
then the $1.75 per roll I paid for the Pro Max was not a terribly
bad
deal.
