circa 1996. A wager using a Nikon F2 with faulty photomic head from the paper’s junk cupboard. 14+ stops, Print developed to N-2.5, Fuji Neopan 400 pulled to 200 (N-1), Afga Rodinal (another -1), paper pre-flashed (-0.5).
circa 1997. Junk Cupboard handheld Hassleblad 500c/m (?), Ambient light, N development and printing, black hair extensions against a black background (bedsheet thrown over a door) highlight detail in the face.
A 2017 example of where ETTR would fail as the accordion player was in the shade, the skin tones would have had to be raised and would be noisy, so the exposure was set by touch to blow the highlights on a 10+ stop scene. Exif data should be intact.
The images above could be considered examples of visualisation, and knowing how film or digital will respond.
