These are great, Gerry. Thanks for sharing. Learned some good things. :) Among them, I finally understand what ISO actually does. I know it increased the film "speed" in old days, but understanding that today doesn't create noise but simply amplifies whatever is there (however it does that!) is super helpful.

Good ones, Gerry. Clear and engaging presentation.
