Whoops.

I have a roll of BW400CN I accidentally rewound without shooting, hit the rewind button on my canon. How do I get it back out so I can use it?

You need a film puller. However, here is a link to a easy DIY.....

If you bought the film at your local camera store, they probably have a puller and will pull it out for you.

even if you didn't buy it there, they likely have one!

Lightly moisten the leader of an undeveloped roll of film (saliva works) and insert into the target cartridge an inch or so. Tighten the spool on the target film, pull out the moistened leader. With luck or practice the two leaders will be gently and quite temporarily joined and the target canister will give up its leader. I've done it, so I know it works, but it is a little wiggy. (Or you can just get a film retriever somewhere).
