I asked Tom if serious photographers were taking notes after they shot every frame, because they always knew the shutter speeds and f-stops of every photo they'd ever taken. It must have been a real effort for this guy not to laugh as he patiently explained to me that all that information (and much else besides) is part of the digital file that is your digital photograph. So I give him great credit for not openly making me feel stupid, but I still was far from sure that I'd be able to locate the information when it came to real photos taken by me myself unobserved and unassisted.
Therefore I can report (with some pride) that the dancing lady above was shot at 1/20 of a second with an aperture of f/5 and ISO of 1600. The ceramic rhomboids were shot for 1/2 second with an aperture of f/9 and ISO of 1600. I was trying to make two similar-looking pictures, one with a faster shutter speed and wider aperture, the other with a slower shutter-speed and narrower aperture. I was not afraid to "crank up the ISO" as Mr. PhotoTrainer ardently encouraged.
