all i remember of the old times were when you had a camera with a single roll inside, you would just click and never know how it came out until you printed them, and the camera had a sort of counter to help you count how many shots left

Exactly. I remember my parents going abroad from time to time and coming home with a few rolls of films, then my dad angry because some of the photos were blurry and out of focus. In those days you could not afford to take two shots of everything.
