Description
The YE0226 is designed for the evaluation of the color rendition of HDTV cameras. The chart consists of 36 color patches and a 9-step gray scale. In addition to the primary and secondary colors the test chart contains mainly the colors, which are critical in reproduction, e.g. dark and light skin tones, foliage, blue sky, orange, violet and others.
The chart consists of 36 color patches and 9-step gray scale. Besides the primary and secondary colors (blue, green, red, yellow, purple and cyan) the test chart contains mainly colors, which are critical in reproduction, e.g. dark and light skin tones, foliage, blue sky, orange, violet and others.
The colorimetric reports of the 36 colors are shown on the following page.
The 9-step gray scale is graduated as follows:

The density is based on the 1st step of the gray scale.
Date
Some of the filter foils used are not fade less, especially when exposed to sunlight (ultra violet light). We therefore recommend to store the chart in the folder or case when not in use. We also recommend and offer a recalibration of the chart after 3 years of regular use.
