Two questions Seanie

Civil or astronomical twilight?

and

If I stick my finger over the lens does it count as a landscape?

Technically, twilight is the period between darkness and full light (and the other way around), so, unfortunately, a sunset (and sunrise) would not count.


What if the sun is not fully above the horizon?
And are we measuring sunset/rise at sea level?
