i noticed in the bathroom after i showered this morning that the light was coming in through the sides of the roller blind on the the window, sharp as you like where it came in and spreading out as it got further from the window. i could see the light bouncing off the steam moving round the room so i'd assume mist/dust would be needed in the forest.
maybe keep an eye on the weather and get an early start some morning when the conditions look right.
that pic looks assume by the way
