Now granted, I didn't get the idea to show these photos together until AFTER I took them, so I'll be the first to admit I probably could've gotten a more interesting sample, but oh well.
Last Friday I was over at a fellow karate instructor's house for an instructor gathering. I decided to show up slightly early because he had been telling me how awesome his backyard was, and he had a great waterfall to photograph. As I've learned from various sources, the best times to photograph a waterfall are at sunrise and sunset since there's not as much extraneous light, so you can control the shutter speed better. Why would you want to do that? So you can control what the flow of the water looks like. Taking photos at a really fast shutter speed will basically freeze the action, which is great for sports photography. However a flowing waterfall frozen in time doesn't look the most exciting, so slowing down the shutter speed will give you a sense of motion.
Here's the same photo, taken at 3 different shutter speeds, one right after the other. Like I said, I *should've* taken one much faster too, but well, I didn't.
Even with just that tiny sample, you can still see the difference in the water flow. I think I actually like the 1/8 second one the best though.
In any case, here's my favorite photo from the evening, and one which I just ordered as a canvas from APC.
