shutter speed

this week, in my photography class, we are learning about shutter speed.

we were instructed to take two pictures of water: one where the shutter speed is fast, freezing the water - and one where the shutter speed is slower, creating a flowing effect. here are mine:

{1/640 Shutter Speed} {f/3.5} {ISO 800}

{.3 Shutter Speed} {f/22} {ISO 100}
