That's the real art of it. I used to haul my DSLR around, try to meter the scene at f/22, apply some multiplier, etc, etc. That got old fast and didn't work well anyway. Now I go by experience and intuition and a few basic rules:
- bright sun, subject fully lit: 15 seconds
- bright overcast, subject not in shadows: 30-45 seconds
- bright overcast, subject partially or mostly in shadows: 60-90 seconds
For other situations, you kind of wing it based on that. Every camera will be different though. The good thing is that when your exposure exceeds about 30 seconds, you have a fairly wide margin of error -- e.g. expsoing for 10 seconds instead of 15 could mean extreme underexposure, but exposing for 55 seconds versus 60 probably won't make much difference.
And yes, the curved plane is quite a unique effect. Fun stuff!
