I'm gonna geek out about my camera a little... fair warning. I did something today that I could not reasonably do before I got my digital SLR: I shot useable photographs at ISO 1600 and 3200, right next to shots at ISO 100. If you've ever had to agonize over what film to load in your camera (and in particular, what speed [aka ISO]), and especially if after two shots you desperately wanted something radically different, then this is an amazing thing.
We went to the Monterey Bay Aquarium today... they have an amazing jellyfish exhibit. But it's rather dark. Aside from the jellyfish' own bio-luminescence, there's very little light to be found. Not nearly enough to take a photograph with. But turning on your flash will pretty much ruin the photo of the jelly.
So what to do... ahah! On your digital SLR, you just crank the ISO dial around to something absurd like 1600 or 3200 (which doesn't even show up as a number, it just reads "H" for "High"), and snap away. But aren't the results incredibly noisy, you ask? Not on a Canon CMOS! 3200 is kinda noisy, but 1600 looks better than most (all?) ISO 400 negative film (and maybe even better than that). Amazing. I'll follow with a post of a couple photos.
