Hi thanks so glad you enjoy! I shot it all as series of raw images with DSLR's. A few of the shots were taken near a friends house that I ran long extension cords down to the river to keep cameras clicking. Most of the shots I used LiFePO4 batteries to power the cameras (links below). LiFePO4 batts seem to work best in the cold, plus they can be recharge thousands of times without loosing potency. Working on new ice flick and will post it here when its finalized. Thanks again!
