We can make a deal. I'll send you some money if you'll send me that 75 2.8 lens for the 6x7...yeah, that's the ticket.
I still have all the Ciba prints I made other than some I gave away or sold.
I made a shot at night at the Fair that I was proud of and ended up selling a bit over 30 of them. Each night before closing they would shoot fireworks over the Sunsphere. I got my 6x7, tripod and Ektachrome 50(Tungsten) and went across the street on a hill and focused using f11, locked up the mirror and with the cable release, exposed when the fireworks were at their peak. I had no idea as to the exposure but used 2,4,and 6 seconds and one of them(forgot which) turned out the best. That's the one I made those cibas from.
