7D + Sigma 150-600mm Contemporary lens: ISO100, 516mm, 0ev, f/11, 1/20second, handheld. I wouldn't normally use this lens for a picture like this, but I've been trying to test out its capabilities in various situations and, more to the point, my capabilities in using it.
Nice pictures. I like the first one in particular. The second one reminds me of the extreme forest fire conditions in British Columbia last summer. I remember how slick the smoke was.
Ryananthony's post reminded me of the fires in British Columbia last summer. I posted this picture elsewhere quite a while ago but think it goes here as well. Taken at Elk Lake by Victoria last July. The yellowish-green hue is caused by heavy smoke resulting from forest fires further north on Vancouver Island.
