Predigital camera. My preference in print film has always been black and white. This photo is from a scan of a print and has been recently post-processed in Photoshop for a slightly warmer cast, reminiscent of the old silver gelatin prints.
No lens or exposure information from this pre-digital camera, taken some years back
Here are my best guesses:
Lens: 100 mm dedicated lens (my favorite portraiture lens going back 30 years).
Exposure? Inside, may not have been on tripod, best guess is 1/60 or 1/125 -- I rarely shot at a slower speed.
ISO? My guess is ISO 200 at a slow speed and wide aperture, a print with high resolution. Not slide film.
