Bolex Stroboscope

A stroboscope disc for calibrating the framerate of Bolex H16 cameras. It has bands for 12, 16, and 24fps, and is meant to be used with the 8:1 drive shaft under 60hz light. If printed at 2 inches diameter, a small notch can be cut in the outermost band, and then it can be taped onto a rewind crank.

The CIELCHab colorspace has the useful properties of being both perceptually uniform and manipulable in a natural way. The Chroma and Luminance channels correspond approximately to what we think of as Saturation and Lightness. Perception is a standalone tool for working in CIELCHab, which also includes a gamut mapping function, an interpolator, and a color vision deficiency simulator.
