12 Weeks to Better Photos: Week 2 - Shutter Speed

I am a bit behind in blogging about this. my apologies!
All 12 lessons can be viewed here 

Week Two is shutter speed. The challenge is take the same photo on 3 different shutter speeds. The goal here is to demonstrate how to either freeze motion (high shutter speed) or blur motion (low shutter speed). Hence action shots (sports, animals, traffic) require a high shutter speed so you don't get that pesky "motion blur" where an arm, or tail or such is all blurry. but sometimes you want that really nifty motion blur, like in a river, or waterfall. That is when you would use a slow shutter speed.

In terms of everyday photos, a neat trick I was taught was to double your focal length, and that is generally what you should aim to keep your shutter speed at. Also, with kids, try to avoid dropping below 1/160, or 1/100 at a minimum.

So here is my photo challenge for shutter speed. A neighbour's fountain:
1/1000. See how the droplets are all nicely frozen in time? High shutter speed
1/100 average shutter speed, but for this, it just makes the water look spitty
1/15. I would need a tripod to really show this one as there is probably hand blur going on, but see how the water near the fish's mouth is almost translucent in a continuous flow?
