Someone posted the link to this album in the comments a while ago but I made a post to make it more visible because everyone should see this. Now we can get nostalgic together and unironically say that we were born in the wrong generation. Listen to sovietwave while browsing for the full experience.
Film does things when you do long exposures that digital can't without heavy use of photoshop. To get photos like that, all you have to do is setup a tripod and a shutter cable, and do a several second exposure. (There is math involved to determine how long). Most of those pics the exposure looked like just a few seconds, but I saw some that had to be a few minutes.
Also, Soviet cameras are quite cheap. On the order of $30-100 for most 35mm models on ebay right now. Look up Zorki 4k. They are Leica clones, basically.
