This is a video I made for a user on Reddit r/vintagecameras to show them how to use a camera we both own. This is a Russian made camera that I haven't shot in over 20 years but took beautiful images.
I made a few errors. Such as the upper lens is your viewfinder lens and your lower lens is called your taking lens.
Also, find a wordy example of the exposure triangle I made here years ago. I usually walk people through it on paper, so hopefully, it's not too overwhelming: https://imgur.com/gallery/QNWcVUK
