schoolboy error

SILLY. Must remember to change out of ISO 400 after walking home in case I later head back out with a tripod.

If I try and take a picture on the way to work in the morning without changing out of whatever manually-set long-exposure I last used the evening before it's easy enough to notice and results in only one wasted over-exposure. It's slightly less obvious going the other way. Twelve shots RUINED. Well. Twelve shots with more noise in them than night-shots should have.
