Provoke – are, bure, boke

“Grainy, blurry, out-of-focus” A small movement that continues making changes in the way of picture making.

Yutaka Takanashi and Takuma Nakahira, critic Koji Taki, and writer Takahiko Okada. Started a short lived magazine: Provoke.

Boke, usually: ‘bokeh,’ is the remainder of this stylistic trinity. It has been reduced to meaning the ‘out of focus’ rendering of a lens. Bokeh and ‘diffraction limited,’ form the recurrent, frequent topic in the online life of photography. A limited life, but it won’t die.

I’ve collected a set of videos so those of you at the table can have a brief, but worthwhile foundation of the provoke style.

Provoke (Purovōku) was an experimental magazine founded by photographers Yutaka Takanashi and Takuma Nakahira, critic Koji Taki, and writer Takahiko Okada in 1968. The magazine’s subtitle read as: shisō no tame no chōhatsuteki shiryō (Provocative documents for the sake of thought). Photographer Daido Moriyama is most often associated with the publication, but Moriyama did not join the magazine until the second issue. Provoke lasted only three issues with a small print run, but remains an important cultural artifact of the postwar era.

Tricolor Exposure Method

A Post In Three Parts

this is the first post. starting steps.

Bad Names

Additive and Subtractive printing.

by modifying the color of light, we affect the color of the print. Simple enough.

The photograph is an illusion which stands in for something else. If done well enough, the magic occurs; sometimes reproducing reality, while others replacing, or replenishing it.

the most consequential artists of the past 100+ years have asked their questions using the language of color.

Two Modes of color printing: white light, or additive (tricolor).

A small cardboard box with plastic exposure wheel and a color wedge calculator. This was probably the most used hobby way to color printing. It also probably caused more people to try, then leave color darkrooms. The real heritage is the mass of drums and rotating bases filling landfill and ebay. [Canadian company that made roller bases and tanks that he produced for several companies. With small detail changes they were marketed, at the same time, by Simmard, Unicolor, Beseler and Omega.]

Specialized Enlarger

Phillips PCS tri-one enlarger introduced in 1979; six years later, Beseler introduced the Minolta 45a at PMA 85. Both used primary color, aka, additive filters. These are narrow pass filters similar to the effect of using Wratten 70, 98, and 99 filters.

The Head is the light source that sits in the enlarger replacing the other beseler light source. It uses EU (exposure units) to control color and density of the print. These range from 0 to 250. Each 30EU is 30cc in subtractive filtration, which is a density change of 1 stop.

The Controller is the main portion of the unit. controller and head are connected by a cable which you do not remove. Take care not to kink or twist it much, since it is a fiber optic cable that can be broken without showing external signs. Once it breaks, you need to find a new complete system I use the 45a on a Beseler. It could also be used on an Omega D series.

My main use is to print color negatives. I also occasionally use it to make separations used in assembly processes. Kodak Pan Matrix film would expose well at 100,70,90 for Kodak Ektar film.
