Basic's for calibration... (and logic order)
- Reset the picture mode
- Set gamma target using the gamma control (I recommend 2.2)
- Turn off all enhancements
- Put up a 50% white window pattern. Put your software in continuous read mode. Change color temp setting, find which setting is closest to 6500k (D65)
- Set brightness/contrast
- Adjust white balance, 2pt (just get it close) then 20pt
- Adjust gamma (using 20pt white balance)
- Adjust color
- Go back through steps 5-8 and verify one thing didn't mess up another
It looks like you are targeting 100% saturation...
* Use smaller window patterns around 10% in size; do not
use full screen patterns
* Use the same size pattern for gamma
* Try 75% patterns for color (also use same size pattern here)
* Check color tracking when you are done adjusting the CMS, this will really tell you what is going on.
* If gamma is sloping on one side; remove any gamma you may have adjusted in the 20pt (rest & redo white balance). Then try adjusting the 2pt white balance controls evenly up and down for coarse gamma adjustments. Just remember to keep re-checking gamma fully as one point will effect the other. Basically view the 2pt as coarse gamma control; then follow up using the 20pt fine control.
If you set color using 100% patterns on a TV which is perfect this is OK (almost no TV is like this). When watching TV you will rarely ever watch anything at 100% saturation, so it makes more sense to calibrate for 75%. Also, If you check color tracking you can try tweaking things to get tracking more uniform.
Please post the color tracking when you are done too
