The photos were done with a Nikon F2AS camera and 35mm f/ 2.0 Nikkor lens on Fuji Super G- 800 print film and scanned from handprinted 8 x 10 color glossies with little correction in Photoshop , except to remove a greenish cast in some shadow zones, owing to a vagrant mercury vapor lamp shining in from a nearby trailer court...aaarrrggghh!!!.

Exposures were in the 25- 45 second range at apertures from f/ 2.0 to f/4.0 and we lit parts of the scene with a powerful flashlight filtered with studio gel filters to convert tungsten color back towards daylight. The buildings were "painted" with the light using 4 second brush strokes, exposure determined with a Minolta-IV incident light meter.
