: By now you ought to have figured out which line is the so called "Gamma Target" in the graph - and even if you didnt - google picture search for bt1886 gamma HCFR should have answerd your question as well...
The exact "body" of the curve is calculated for the individual black and white points measured(/substituted), so again dont look at what gammas the curve actually touches - just go with the target gamma line.
As for what I use for critical viewing - thats a very personal question.
And you are especially lucky, that I am manly enough to share my choices and am not shattered in my confidence as human being, and as a guy - whatsoever - by making it public.
As you might have guessed, as I had to watch them over and over, and over again -I chose clips were it would take some time for me to get bored by. Not a fan of this style of music (music? you'll see.
) in particular, just appreciating the "art".
And that they are short so you minimize the time searching for scenes.
- Highly saturated colors, greyscale - last shot is the greyscale/white shot I spoke about when talking about the adaptability of our eyes to a whitepoint (D65 vs D75).
- Undersaturated colors. Highly postprocessed, except very few shots outdoors (most are color corrected as well).
- used ONLY for the on set shots, with warm lighting and a heavy emphasis on skin colors (dont use the alleyway shots, or the classroom shots (heavily post processed, lighting isnt uniform, ...).
Then I use three more videos in this set, which are especially challenging over a broad palette of colors (all kinds of skin tones, blue skies, greens, lighting conditions..), just to notice "if something feels off":
_Download_ HD versions of the videos (JDownloader f.e.) and play them only in a player (software) that you have verified as "accurate" by doing a pattern measuring run through the player (GCD Calibration Patterns) - trying to eliminate as much uncertainty potential as possible, in each step.
Also when I did a major change in configurations, I always checked against daylight scenes in "Quantum of Solace" - but you are invited to find different and/or better material for critical viewing.
