I have a lot of film cameras and most them are really cheap. I think the cheapest one are those disposable cameras, around 5 dollars each (film included). Here's just some of the cameras I use: Practika MTL 50, Zorki 4, FED 4, Chinon CP-7m, Olympus mju II, Yashica Lynx 14, and some point and shoot cameras from Kodak.
In terms of the films I use, I always try to test/use as many as I can. When I started I would use cheap films like Kodak Color, 200 ISO. Now I'm experimenting with Portra 160 and Ektar 100. For black and white shoots I'd use Fomapan, Agfa APX 100 and Tmax 400 from Kodak.
I think it’s the minimal tools that give you the liberty to express your emotions into pictures. You are limited to a number of frames, and also in terms of time. If you go on a trip with a disposable camera, you cannot shoot 50 frames, and then pick the one you like. You have to think a little about every shot, compose, shoot, the go on.
I think that using such minimal tools gives you the liberty to express your emotions through pictures. Being limited to the number of frames and considering the time it'd take to shoot is definitely a blessing in disguise. When I started using digital cameras I had a lot of fun because I find that I was good at it (Well, better than my friends that is). Using it often made me realized that it disabled me in knowing what's really going on behind the scenes of how photography works. So I tried film photography and I just love it! Borrowed an old Yashica from a friend and fell in love with film photography since then. I simply enjoyed not having to deal with batteries and all the manual controls.
Just get yourself a film camera from eBay or anywhere you can possible! Caution: it's addictive.
I think that every parents should give their children a film camera even if it's just a disposable one. After printing the photos, they'd become memories. Being physical, not stuck in an archive on some hard disk or in the cloud, where there's a possibility that you'd forget about your password to access it. Maybe after 20 years, you'd run into the photos by mistake and feel such wonder!
There's many great things you could do with film photography like swaps. You CAN'T do swaps with digital cameras! I actually just started a film swap project and I'm sure that I'll continue to swap films with people from all over the world.
