try to set brightness and contrast correctly first and then redo the white balance (20/30 - 80 but use the gamma module in CP lowering/raising ALL 3 colors(gain/cutofff) should raise/lower your gamma
I use the gain and offset to correct the gray scale colours (white point). If I use these later to do the gamma won't that change the colour of gray?
Right now, after adjusting the gamma the best I can using the B&C controls, my brightness is set at 52 and contrast is set at 49 (50-being the standard starting point), which is what it was set at when I used the Disney wow disc to set my B&C before I got ChromaPure. Coincidence? does having the proper brightness and contrast actually help give a proper gamma curve? I think that's a rhetorical question. I know the THX calibrator that did my X-55 never touched brightness or contrast but used custom gamma to get everything close. That's why I didn't set B&C during my calibration and only tweaked them trying to fix the gamma, no custom gamma controls. I still have lots to learn.
I still love how easy it is to use ChromaPure and how good the picture looks when you're done. My eyes were nowhere close to being accurate.Edited by Crabalocker - 2/17/13 at 9:58am
