Cold snap up here in Montreal..this is an ice formation on the garage window. Tripod,cable release, and 100 mm macro lens. Canon 7d.
Very pretty. I tried to take some of the same type pictures with my cell phone and they didn't turn out very good. Should have had my dslr with me instead. Oh, btw, it's -13 degrees here in Colorado right now. :-) Cheers.
