October 19, 2007: SMPTE Colour Bars

I’ve been looking at colour bars- the vernacular as a starting point. Colour standards, degree zero.

As I’ve been thinking about certain colours that are considered degree zero as a place to start. The old television test patterns like the SMPTE colours bars used in countries with the NTSC video standards tests for how the viseo signal has been altered by recording or transmission and for adjusting the colour space and brightness of a television monitor.

Besides being a beautful image, with definitive colours- it is recognized by many people as the first image you see when looking at video art. I’m not aware of any equivalent in the broad field of digital arts.

The newer HD SMPTE colour bars have a 16:9 ratio.

I’ve proposed to use this image within the MA_DA wiki as a place to start for the spectrum project website.
