Day 4: controlling the faucet - learning ISO
(Woo hoo! Batteries in the camera! Maybe one of these days I’ll start up another stock of rechargeables - I’ll need them for the kid, anyhow.)
“ISO is a measurement of how your camera responds to light.” Low ISO = sharper photos; high ISO = grainy or noisy photos. The lesson this time was more of an observational exercise - lock your shutter speed and change ISO by one ‘click’ per photo, then see what shutter speed your camera has chosen.
Alternating from top left: ISO 80, 1/500; ISO 80, 1/750, f3.2; ISO 100, 1/750, f3.2; ISO 200, 1/750, f4.5; ISO 200, 1/1000, f4.5; ISO 400, 1/1000, f6.3
I’ll be honest, this exercise didn’t do much for me. I don’t know if it’s because I moved my shot too much (shaky hands, even perched on my knees), and therefore changed the lighting; or because I still haven’t permanently grasped shutter speed. I still keep having to remind myself. I’ll probably go back to shutter speed tomorrow, then re-do Day 4 with a steadied camera.
Day 5 is Part I of Understanding Aperture; there is no lesson, so I’ll just use that as my Day 5 tomorrow, and mash Day 5 and Day 6 together.
