This is a technical point to make about shooting. And it is probably not relevant to the smart phone/iPhone crowd because you don’t have a real camera. Noise is what the purists complain about when the ISO is too high and the image is grainy. And I say, you could not even hope to get an image before digital was in wide use. Right now the cameras are able to get a decent image in virtual darkness. What latitude and opportunity! This image is at ISO 6400. Don’t bother if you don’t know what ISO means. It’s an old film term. And then I let the camera pick its settings. All I did was set the parameter that the minimum shutter speed needed to be at least 1/100 sec. And then I enlarged the image. Yeah, pretty neat! Sometimes I surprise myself. So this image in virtual darkness will not make purists happy. Sure zoom and shoot with flash and so forth. Street photography in the dark is an art. And this cat was not waiting around for me to set up things. Right tool right place, cameras rule!
