EX1 Stronger Plates ? NanoFlash Brackets by Westside A V

This system (Plate/Shoulder Mount) is designed to line up with the LCD screen or the rear viewfinder by adjusting the angle or the long shoulder mount.

I've read the Negative spaces HD Monitor Calibration article that explains the non-SMPTE bars of the EX1R. However, how do you set the color without blue mode for the LCD?

Hold a piece of dark blue lighting gel between the finder and your eye, then adjust using the "blue only" instructions. You only need this for saturation and color balance adjustments.

With a free color filter sample set from any of the filter gel manufacturers, select the darkest, purest blue to use for calibration.
