A walk in -22C today, getting some half-baked shots of winter light and ice; I was freezing and my equipent were soon on their edge too, the Sigma zoom getting stuck and rigid (no autofocus in those temperatures). But I am happy I did it: a morning walk listening to the deep rumble of Pyhäjärvi ice cover cracking in mile-long crevices was an experience worth the discomfort.
Edit: I keep a (low-bandwidth) copy all of these shots in my own server: http://unet.fi/pics/2006-01-22/
