Metering when the world disappears.

Fog lies to your light meter. Everything is bright grey, so the meter asks for less light, and your fog comes back muddy.

Fog lies to your light meter.

风、光线与慢慢走

My rule in white weather: overexpose by two thirds of a stop, and expose for the brightest shape you still want to keep.

Fog is not empty. It is the frame deciding what to hide. Give it room, and it will draw for you.
