I am in my late 70s with health issues and Covid is around, I do spend time in my chair writing SF managing my pills and stuff. I am a retired Senior Software Quality Assurance Engineer. Before I retired I was testing time of flight mass spectrometers. Science is one of my hobbies along with...
I want a formula to calculate the size of the image on the camera sensor. This tells me how much resolution an image will have, If I know something 100 feet away will require 1000 pixels to show a face I would have to use a longer lens or move closer if the formula said I would only cover 300...
