I've updated my signature for the gear info. That will be useful and take out the gear guessing. Thanks for excellent explanation. Doug, as usual, is very thorough!
I've watched some TV and now I can visually tell what is wrong:
- With darker scenes (shadow, indoor, ...) the image is too dark. I've used power law gamma with 2.2 exponent and a 0 cd/m² luma target for black. My tv obviously does not go that black so the gamma at the low end should be 2.15 - 2.18 rather than 2.2 I guess. However, Calman does not give me a plain Y control like the Iscan Duo Control Panel software. So I have to adjust R, G and B and I've got no idea which one to set higher. The Y control would preserve the RGB ratio for me (dummy proof):-). Is there a good way to go about adjusthing Y?
Bright scenes look supberb!
- I think this one has to do with clipping withes: upon detecting the Iscan Duo, Calman presents a full screen pattern like this one
(comes from another site, I'll take a picture later)
Now the portion to the utmost right has a pink hue. It does not show up on my grey scale, and I can't spot it in a 90-100% white pattern (10% of screen area) but it's there on that test pattern and quite clearly too. Does that indictate some sort of problem? Maybe I should get the AVS pattern which show the bars beyond 100% and check whether there is discoloration present beyond video level 235.
ps: I like autocal but I also like to do it myself because it is fun and I like to learn.
