Vivid collection

I received the ND Polar filters I ordered last weekend for my drone today.
They look very nice and I’m curious how they will perform high in the sky.

Tonight’s photography course, lesson 2, was great! Everybody was enjoying it and the relation between shutter speed, aperture and ISO became clear to all.
The lesson was supposed to last until 21.30, but everybody went home way after 22.00.
