The Color Box

The color box offers a better way to take manual tri-color photos. It does a good job blocking light from entering the lens from the rear. It accepts 100x100x2 mm sized filters.

The photo shows it is using these three 100mm filters:

Kodak Dark Red #29 Wratten
Kodak Deep Blue #47 Wratten
Kodak Deep Green #61 Wratten

Experimental Color Wheel

For our monochrome cameras, we're working on a color wheel. This one is a 3D-printed plastic and 320mm in diameter. Using a color wheel should give much better color than a Bayer-type color filter, but it is not suitable for moving objects.

It uses these three 100mm filters:

Kodak Dark Red #29 Wratten
Kodak Deep Blue #47 Wratten
Kodak Deep Green #61 Wratten
No yellow due to lack of software support, but yellow can be added later.

100+ years old technology

A Russian, Sergei Mikhailovich Prokudin-Gorskii, took tri-color photos over 100 years ago using glass plates and a color wheel. It is interesting to go back in time and see his photos. See his photos at the Library of Congress.

Status May 2017

For now we're doing 3 colors manually, in the future we may build an auto color wheel, though there are difficulties with that so we're holding off for now.

Still life is straight forward, but it is possible to take images with people also if they can stay still.
