I would like to announce a new release of the project (version 0.4). A lot were added (already totaling to 3825 files!), new formats, new patterns, enormous amount of calibration patches. Please download
So, to highlight the most important. On the HDR side support for HLG
(Hybrid-Log Gamma) is added. As well as good old SDR and FullHD is supported too (and there are plans to go to ICtCp, ideas how to get into DV and other dynamic meta formats). For HDR/HLG there is BT.2111
color bars test pattern (simple, but as far as I know not yet available in any test file set).
There is now PLUGE test pattern, so the most important task of setting black level
is covered by the test set for all supported formats.
Calibration patches now go in 5%, 10%, 20%, 50% window and fullscreen sizes. Among them 5% step grayscales, 1% near-black steps plus whiter-than-white (105% and 109%) steps. Also 10% step saturation sweeps
for primaries and secondaries (supposedly CalMAN compatible, but I've no chance to verify, so please let me know if they are correct distributions or not).
There is also checkerboard patterns (and it's 4K versions reveal a serious bug on my Nvidia SHIELD TV)!
So, please download, test, give feedback (I really need one, at least let me know this work is needed for someone!), ideas, needs, and better yet - contribute. I am trying to update documentation
but I really need help from someone with native English to review, correct, make it pleasant for readers, and of course writing some articles from scratch for the project is always welcome.
