Photography
I was given a Pentax 35 mm Camera. What it had built into it was a light meter. I could see the meter inside the viewfinder. I could adjust the aperture on the lens until the light meter read in the sweet spot for correctly making the exposure light appropriate. This made a big difference, I was adjusting the aperture and producing good pictures.
Do all film cameras have a built in light meter?
