I decided to re-enact the old one because It lacked detail, and I wanted to break in my new lens I got not long ago.
1 canon 550EX about half a meter in front of the lens pointed up to illuminate the snowflakes at 17mm setting about 60° tilted forward (so closer and further snowflakes were lit up too). -triggered manually
approx 2 sec exposure, at around f 5-6 iso 250
This was not taken at 2AM like the first one (this was taken at approx. 3AM christmas morning) :)
Used DXO to render it in b&w, med-high contrast, minor levels correction in PS, uncropped.
I think the new one feels more refined.
