Light meters and densitometers were once indispensable for a complete understanding of how our light, film and chemistry all played together. Now they're built into our cameras, computers and software. Densitometers were mandatory to running consistent Kodachrome and Ektachrome lines. Every day began with running test strips and reading and charting densities through filters to determine what had occurred with the chemistry since the last film run; and over night. Chemistry was then adjusted as needed to provide results consistent with Kodak's specifications. Using a densitometer on black and white negatives, together with the Zone system at the subject exposure end, provided absolutely consistent and repeatable results; along with a complete understanding of the various quantities of light being focused on the various emulsions; as well as the effects of the various chemicals, and their times, temperatures and agitations, on each unique emulsion. These understandings do in fact translate quite well to using our digital sensors and understanding both their advantages and limitations. a note off the iPad, George On Jan 16, 2015, at 10:13 PM, John McMaster <john at mcmaster.co.nz> wrote: > Would love to have a densitometer. Ah well.
