I like this image and the challenge so Tom kindly sent me the file to repost.
This is a common situation in industrial sites. Just poking ones camera through a small space and getting that picture is commendable. The image is plenty impressive as is. There's a lot of power there and the blood red paint at the foot of the massive steel pillars seems to say something about the work that went on here and how it made or borke men's live's.
Several things I'd consider, and this might annoy purists who might insist that the image should be shot as is on site. I might swing my camera arounf the optical axis to get more of the industrial space to the left and in the front so as to be able to have compositon choice after the fact.
One can also use a wider angles with the Sigma 12-24 or the Canon 16-35.
I'm thinking that a Better Beamer would be great to throw light all the way up to where the men would be in the lift.
Anyway, I'm glad to have this link repaired for further enjoyment!
