March 1962 version Yashica Mat twin lens reflex medium format film camera.

I was processing this picture for an ebay sale using the basic processor that came with my camera and I noticed a control I'd not noticed before. I clicked it and got this!

1979. Mamiya TLR medium format camera with Sekor 135mm f4.5 lens. Ilford FP4 black and white negative film processed in Ilford ID XI, scanned using CanoScan 8800F.

Male Portrait - Silhouette. Negative exposed in 1979. Mamiya TLR medium format camera with Sekor 135mm f4.5 lens. Ilford FP4 black and white negative film, scanned using CanoScan 8800F. Converted to sepia using Lab Colour Space in Serif PhotoPlus software. The deckled effect around the central square was what I call a 'happy accident' and I decided to leave it in.

Scanned Kodak colour negative film. Processed to 'sepia' using Lab colour space functions in Serif PhotoPlus software. Mamiya C220 camera. March 1979.

The camera has a 'Kodak Ball Bearing Shutter' with speeds B, T, 1/25 sec., 1/50 sec. Aperture f numbers are not specified on this model. Instead, the aperture scale uses numbers 1 to 4. I believe that these digits convert to present day f8, f11, f22, f32. The lens appears to be the '2-element achromatic doublet', focal length about 98mm, maximum aperture about f8. Apparently the placing of the glass elements behind the shutter was standard for this lens, so there is no glass 'on the front'.

HDR and multi-layer treatment performed using SilyPix Developer Studio and Serif PhotoPlus software.
