This started out as another HDR (high dynamic range) experiment, but ended up as kind of day-for-night faux moonlight type thing. Funny old world.
Haweswater again. From the same very wet day as the previous shot... There were two original exposures (RAW, two stops apart) but after a bit of tweaking exposures in the RAW plugin and playing with the channel mixer I ended up with 7 distinct layers plus a few levels adjustments. The different images were manually combined via airbrushed layer masks.
