Problem IS Darin does not understand what gamma really really is
especially with respect to a normalized tv signal voltage.
What quote is that from year's ago that you apologized for? Just last year you said that gamma doesn't apply to digital. That sure wasn't years ago, although you did spend years playing tricks with the word "linear" to try to make it look like Dr. Soneira supported your position about the highest on/off CR possible.
After all these years, if your position about the highest possible on/off CR with REC.709 isn't 219:1, then what is it? You've been arguing against on/off CR for years, so you should be able to answer that.
And once again you play this trick claiming I don't understand gamma, yet you still can't answer Chris's question about what really happens and avoided my question for years about what light level a 10% video level would result in and when you finally attempted it, couldn't even get in the ballpark. So, if you understand gamma and I don't, then kindly tell people approximately how much light should come off a display for different encoding levels if (235, 128, 128) is 10 ft-lamberts:
(128, 128, 128): ?? ft-lamberts
(20, 128, 128): ?? ft-lamberts
You can add lots of words about how well you understand a subject matter, but when it comes down to actually answering real light levels that a person can check to see if you have a clue what you are talking about, you add post after post with no answer in order to get as far as from the specific questions as you can.
As you have done in this thread. What are you up to now, about 35 posts since I asked if you agreed with Poynton on one specific thing and still no answer. Not even that you don't know if you agree with him or not.
