1) i plug the i1d3 into the USB port and Win7 recognizes and showed up in 'device manager'
2) launch hcfr, select the proper settings and i1d3 also shows up as a meter.
follows are screen shots of my gray scale measurements. you guys help me interpret the results, they look pretty bad to me (based on my limited knowledge).
I have an 8350. If they are similar, I found that the first-level menu "skin tone" setting is a killer. In graphing its behavior, it appears anything other than "0" acts as increasingly horrid red cut / green boost.
The choice of "color temp" used as the start point makes a difference too. General consensus seems to be "start at 7000." Picture mode of choice is "Natural, " which is where I took this data set. I need to look at Cinema.
With all data reset to default, I graphed each temp to observe where R and B (which had distinct slopes in their data) intersected or crossed the G data (which was really pretty flat!) at 50 (arbitrary but seems logical). I ended up at 8500 as a base. Or was it 8000? Anyway, I ended up with a "symetrical" gain-offset set, for example Green stayed essentially "0 / 0", Blue offset +15 Blue gain -15, Red offset -2 Red gain +2. It really tamed a lot of humps/dips in my graphs. I cringe at the amplitude of the big blue numbers, but that's the best I could get in "Natural" mode.
