@WayneCollins Color photography was available in the 60s, but most people today don't realize that color itself wasn't as ubiquitous as it is today. In those days, you had to pay per minute for color, and it wasn't cheap for some of us.

I remember back in the early 90s my brother and I only got 60 minutes of color per week! Obviously you'd mostly turn it on when someone was going to take a picture of you, but most candid photos were inevitably going to be black and white.
