I am becoming more and more enamoured of these long exposures before sunrise. This was a minute and thirty seconds (by my count) actually 88 seconds by the camera count so the one one thousand, two one thousand count was quite close. I am startled by the amount of information I can extract. Using this I can emulate HDR with none of the weirdness. Quite a bit of post processing change, but really mainly increased the exposure, increased the warmth then darkened the sky to get here
I suspect it must have something to do with the diffuse light off the snow, or previously in fog. Certainly has never seemed to work well before the snow arrived. Someone with more brains than may be able to explain if this is true or I am deluded
