Let's work out an imaging problem for a simple single lens camera. Where do we align the lens and film in order to focus the image?

As an amature photographer, this one was really interesting for me. I can now imagine what is happening when I turn my focus ring. Plus I always wondered how auto focus work. Now I can imagine the computer quickly checking signals from various points on the sensor and seeing what changes happen to calculate optimal focus of light.

I still use a film camera, and this was kind of cool to see. With my lens with multiple elements, I wonder if it is just one lens that moves, or if all 4 move. Really cool to see the principle behind it.

Good to hear. Yes, in a real camera there are multiple individual lens elements within one housing - what the camera industry calls a "lens." Cheers, Dr. A

@@bronkolie🤦‍♂️ lol. I don’t know what’s more brilliant haha. That’s why he appears to write with his left hand. I see nurses writing inverted all the time on windows to convey a patient’s information to others outside their room. So I assumed others do it too
