Tokihiro Sato

Tokihiro Sato uses a mirror or torch to create photographs 'Photo Respirations' that trace time through light, a counterpart to Hiroshi Sugimoto's concerns. Interesting for me, when I was researching initial ideas I was looking at signalling using mirrors and the sun, thinking 'this can't make a photograph', but from depth of exploration comes discovery....images from here

I love it when photographers are properly open with technique stuff like this, and don't give it all the coca- cola secret recipe tale; although truth be told i struggle to be open about process:

'AFH: What about this next photograph [Untitled, Morrissey 23]?

RM: Our nickname for this one is "the hulk" because he's all green.

AFH: How are you getting these colors?

RM: The colors are the result of film experimentation. Before I go to the concerts, I expose the film to different lights - Daylight, television light, tungsten light, sunsets, colored lights, morning light, basically all kinds of light. I expose the roll and then shoot it again at the shows. Between exposing the film and utilizing the intense stage lighting, i've got a process down to achieve new color palates.'
