Keeping a Logbook for Film Opticals

Above is a half page sample from a logbook I kept when I was an optical printer cameraman/operator at Film Opticals of Canada.

Some details....

"Wetgate S-16": a blow-up from Super 16 to 35mm; in this case, the original camera negative is re-photographed to Kodak Vision 5244 intermediate stock (as an Interpositive, or "I.P.").

"Pack": filters of 5 cyan, 20 magenta, and 70 neutral density ("N.D."). This is the filtration decided upon by earlier "CX" (Cinex) colour testing.

"Cam B/U": Camera blow-up.

"L": Lens at micrometre position 1450
"C": Camera (body) at position 0835
"-20 ND comp": remove 20 worth of Neutral Density filter as compensation for the blow-up position (since the value of the light intensity is lower than it would be at a "normal" one-to-one position).

Of course, any such post-production work is now done on a computer.
