Southern Wisconsin: These men are extremely high paid computer engineers working as a team in a 'boiler room' with 30-40 other engineers. The place is kept very dark so they can comfortably see all the detail on their screens. Very hard to photograph in- particularly when there is the slightest movement.
This photo was shot almost in the dark-- at 3200asa- with the Nikon D3. The 'noise' in the high res. version is almost non existent-- the photo has been used as a double truck in an annual report. Amazing quality.
