you can get it most photo stores that sell film (at least in my country), but finding a place that develops classic b&w film is probably more difficult, since it uses different chemicals for processing than for regular color film. but you can also get b&w film that is developed with regular C-41 chemicals (=same chemicals as normal color film). it won't be the "real old school" b&w film like i've used here, but it still delivers very good results and you can get it developed in any place that develops regular color film.
did you develop yours on your own, or did you find a place that did it? I don't think I've ever even seen black and white film... weird! So I'm sure it'd be really hard to find a place that would develop them.
no, there's a shop in my city that develops B&W film. but it's like the only one in the whole country. don't be scared off by this though - i live in a really small country (estonia) so i'm sure the situation isn't as dramatic in bigger countries. it's totally worth trying to find a place though. if you take a look at my deviantart gallery, then all the B&W photos you can see there (except for a few older self-portraits that have been shot with a digital camera) have been shot with real B&W film. although if you really can't find a place that would develop it for you, just get something that's processed with C-41. for example: kodak BW400CN (the CN stands for color negative which means it can be processed with color negative chemicals) or Ilford XP2. both should deliver excellent results.
"To the centre of the city where all roads meet, waiting for you, To the depths of the ocean where all hopes sank, searching for you, I was moving through the silence without motion, waiting for you, I a room with a window in the corner I found truth.
In the shadowplay, acting out your own death, knowing no more, As the assassins all grouped in four lines, dancing on the floor, And with cold steel, odour on their bodies made a move to connect, But I could only stare in disbelief as the crowds all left.
I did everything, everything I wanted to, I let them use you for their own ends, To the centre of the city in the night, waiting for you, To the centre of the city in the night, waiting for you."
haha. well, these cameras are around 30 years old so they don't have any kind of screens or anything digital really. they're pure analogue. there's no way of seeing the images before you've developed the film. that window is actually for putting a piece of the film box into it, so you wouldn't forget what film & iso you're shooting. here's a screenshot from the manua, explaining what's the window for: [link]
anyhow, i really recommend reading the manual. you can find it on the internet.
there probably isn't. you're just gonna have to suffer with the english one like the rest of us i'm guessing the google image might be photoshopped or someone has a digital back for their ae-1, although i'm not aware of digital backs existing for this camera.
