Updating from 3.1.6 to 3.1.8 to 3.1.9 I experienced the following:
Regarding the test patterns: in 3.1.6 they work. In 3.1.9 some of them show black (0:0:0), as pointed out above. And 3.1.8 shows a sort of intermediate behaviour: when selecting a pattern, screen shows black (0:0:0) for a split second, and then the selected pattern is displayed. And yes, some of the patterns have been proven very useful to me.
When selecting the PAL/SECAM colorspace in 3.1.8 and 3.1.9, the targets for saturation sweeps (the small squares) on the CIE diagram are those for HDTV-REC 709. Primaries and secondaries targets are properly shown, as are the Color Checker targets. The calculation of sweeps on the measurements tab seems to be correct though, as are Saturation-luminance and Saturation-shifts graphs. In 3.1.6 saturation sweeps were correctly shown on the CIE.
What happend to the AXIS Colorchecker in 3.1.8 and 3.1.9? I found this a very valuable feature in 3.1.6. In fact, when using HCFR as generator, it was the only colorchecker which allowed luminance sweeps (for primaries). Sure, I can manually adjust stimulus level in the generator set up (for, say, 4, 8, 10 levels....) and run primaries and secondaries after each adjustment, but that would be a rather cumbersome way of doing. Could we please have AXIS back?
Thanks for all the good work!
