Temple Hoyne Buell Hall at The University of Illinois Champaign Urbanna (Perkins & Will, Architects.) The overcast (soon to be fog) was coming in from the South and this sky combined with lighting on nearby athletic fields provided sufficient ambient light for this hand held photo.
Photographed using a Nikon F3 on Kodak Tri-X 400. I used a Nikkor 35mm f/1.4 lens wide open. Exposed at about EI 1200 for developing in Diafine. I applied a Tiffen Ultracontrast filter in DFx. I have the physical filter and should have tried it on this shot.
