Haven't been here for a while, but my fingers seem to have healed, so I'll try again.

The reason that it's difficult for most of us to supply photos, especially interior shots, is (as I stated earlier) that most steel companies do not permit cameras inside the plant: if I drove into the plant for afternoon shift, after photographing trains all morning, and had my camera lying on the seat, security had the right to confiscate it, and/or send me home. I
have taken a camera into work, mostly to photograph the trains, although I also got some exterior shots of a blast furnace. I am unable to post these because I don't have a scanner. I also took some interior shots of the slabbing mill where I worked. These were passed around (surprising how people who professed to hate working there were so fascinated by the photos

) but these were eventually "lost" - too bad because they turned out very well. :cry:
Contrary to what many believe, the reason that cameras are prohibited is not to guard "trade secrets". Rather, companies are worried that a violation of safety regulations, (missing safety equipment, dangerous practices, etc.) or environmental rules will be included in the photo: should it fall into the wrong hands, penalties can be severe (and expensive).
Check out the links that various members have provided, or look for the books that were mentioned. I saw the latest edition of Dean Freytag's book at the hobbyshop a couple of weeks ago, for about $70.00. You also might find the book that I mentioned at a used bookstore, probably quite cheap: in 1968 or so, mine cost me over $120.00.

By the way, I've asked Santa for a scanner. We'll see what happens: I was very good, but I was being naughty at the time.

:-D
