Blue Hourgeneral
The cool, soft twilight just before sunrise and after sunset.
Before the sun is up or after it sets, the sky glows an even blue. Great for cityscapes (lights are on but the sky isn't black) and moody landscapes. You'll usually need a tripod as light is low.
Use this when
- Cityscapes: ~20-40 min after sunset, on a tripod
Common mistake: Waiting until full dark and losing the blue glow.
