F-Stop Printing

fstop printing has been used since digital timers entered the darkroom. In 1985 Gene Nocon introduced a timer designed specifically for the f-stop timing method of printing.

In making prints setting a starting point on the timer (and lens aperture) is first estimated. Using prior experience, yours or others, will get you going. All the emulsion makers provided booklets, guides, even calculators that could get you a good start point.

The “step test” is a basic skill shared by all printers. Making this test strip provides visual estimate of print density (exposure) on a single piece of paper. The timing sequence can be in increments of the same amount or in varying amounts. Linear scale printing can make judging intermediate amounts more difficult than fstop method. When dodging / burning, this is harder with a linear scale.

5+5 =10+5 =15+5 =20+5 =25

linear or fstop scale

With split filter printing using fstop timer with 1/4 stop gradation provides most of the control used in exposing BW prints.

Nocon patent June 1985 for timer element. He made use of British government grant money to make the first ones.

He also had a design patent for the key layout. Simple calculator style system with fractional stops .

His patent spends much of its text describing the calculation method.

A Book to Have Written

We have books, on shelves and within.

Everyone who thinks does some writing, some part of writing. Everyone who has taught has written or talked enough to have written. Maybe speech to text could have done the job better.

I don’t teach; didn’t teach for long enough to become a teacher. I do talk to myself or dogs when they are around.

Because I read and pick what to read by following authors, there are a continual stream of books — small, big — deep, less so. An author/curator of currency mentioned a book, so I picked up a copy. And considering the time difference, the different decades of perspective and history, this book seems familiar. An easy going first year book of ideas, with enough annotation to keep the student moving.

It makes me feel as though I could have, or should have written it.

i wrote about process and specific photographs. That was an age that saw great separation between theory and application. I’m glad that gap has been crossed.

Photography; the Key Concepts. David Bate

His key concepts include reference material as well as interpretations. It is an example of a fine text supplement to studio principle course.

Bare’s book has a beginning middle and end — The other text depicted is a compilation “The Education of a Photographer” Charles Traub.. Classic writings — and available as an eBook.

A small sample of the Bate’s he refactors Fired’s “Why Photography Matters as Art as Never Before into:
