This goes back to you saying to leave the green alone usually.
Yes. Some of my earlier statements may need some clarification, but I don't think I have said anything previously that contracts my current suggestions.
What about Gain at 100%. Theres a big gap between blue and the other two. What would you do?
is the best option to match red and blue to green as well?
There are two commonly quoted "rules" for gain adjustment:
1. Adjust R & B only, do not touch G
2. Only decrease gains, do not increase them.
Obviously there are cases where you cannot satisfy both. Your current gain settings (7, 0, -12) are probably OK, as long as there is no clipping. The alternative would be to cut G (e.g., 0, -7, -19) although in your case you may run out of range for B, and also run into worse control displacement.
When I go back to try again to work the set is the 100/30 IRE still the best combo for 2PT or the 80/20 IRE as mentioned by Holdeemphil?
You can try that in a separate "experiment", but for now just adjust gains while monitor 100 IRE. I wouldn't bother with the offset given the small error that can easily be corrected with the 10pt.
This is why you are being such a tremendous help and I really appreciate your patience with me. it all looks so simple from the outside but once we start digging into it it becomes alot harder.
One can't always use the "cookie cutter" approach. Need to understand what
needs to be done, before deciding on how
to do it.
(As a side note, with the recommended preference for 2PT I would be trying to get RGB close to 100% and lowest dE? This would get xy to 0.313/0.329?)
Yes. I don't know why that would even be a question, with everything else that's been said.
