    Default RGB value of a Grey Card

    Hi

    Anyone know what is the RGB value of a grey card under correct exposure? I am testing to see whether i can use this to set my midtone in my images.

    Thank boss...

    hehehe..that is simple...just half of the 255 value. But if we are talking about 18% grey, does that also mean 0.18 of the 255 value?

    Btw, can I just check where to get the Grey card? Any photo shops will do? ie. Cathay Photo?
