This summer, knipser from Photogen invited me and a couple other photographers, mostly members of the Photogen community, to visit the Arcelor-Mittal steel plant in Esch-Belval. It was an impressive mixture of deafening noise, smoldering heat and a thick layer of dust covering every inch inside the plant. Not the kind of place where you want to change lenses all that often.
All photos: 5D MkII and 24-70 2.8L USM.
Update: I've added a bit of video from the trip, also recorded with the 5D MkII.
