User testing of possible Output Transform candidates

[ChrisBrejon (Christophe Brejon)]

Hey Nick,

thanks for bringing this up and apologies for the delay in replying.

We would therefore like to hear from people who have tested the various renderings, with feedback on their preferred settings, and where applicable which version of a transform they prefer.

From what I can remember, I have always tested the different prototypes with default settings.

The only parameter I changed was “dechroma” on OpenDRT which I pushed to a value of 1. I just checked today (with OpenDRT v0.0.90b4) on all my CG renders and it confirms what I recall from my tests six months ago : I prefer OpenDRT with a “dechroma” of 1. True, my Lego sailors won’t look as saturated but that’s the price to pay I guess.

I just checked ZCAMishDRT v006 and I also like the default settings, even if I see some weird stuff breaking in the blues that I think are worth pointing out (actually, I already posted about them, so I guess I won’t double post again).

For the record, a sRGB sphere lit by a distant light displayed with ZCAMishDRT v0.6, OpenDRT v0.0.90b4 and JzDT.

Update : I tried to play with the different the thresholds (Edge and Head) on ZCAMish DRT v0.6 to fix this blue artifact but I was loosing too much chroma. I could not find a sweet spot unfortunately.

I will try to test Mathias’ implementation this weekend.

Thanks,

Chris
