RGB value of a Grey Card

[nostalgia]

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.

KT,

You can set 128 for all three of them.

Cheers

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?
I have a grey card but the corners are peeling badly...thanks.
