Shot on orthochromatic film or digital processed to look ortho

red car, Ilford Ortho Plus

Had to look this up. Orthochromatic film is a black and white film sensitive to blue and green but not red. As a result black and white tones are shifted and skin appears darker. (Or something like that.) This is a digital colour shot processed to B&W

Actual Kodak 620 ortho film in Kodak Jiffy 6-20

If I want the Ortho look, I just as well shoot a roll of Ortho film to get it. Digital still never gets it quite right. I bought some rolls of Ilfords Ortho 80 film, but havent shot a roll of it yet. I should get to that. Then there is Panchromatic Ortho film like Efke 25 and Fuji Acros 100, which is a slightly Ortho film, but still mostly Panchromatic. Those films work really well with Portraits to darken the skin a little, depending on lighting. Here are a couple shots on Efke 25 done back in 2004.

While not on par with true ortho film some users might like the result of panchromatic film with a dark blue filter. I found some from last year using a blue filter with some cold stored Panatomic-X. Tripod mounted Minolta SRT 101.

First, same car as original post with no filter.
