The Camera | Physics with Professor Matt Anderson | M28-20

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.

That was awesome. Thank you so much for teaching me this.

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.
