Dear Group,

I am having some trouble deciphering the gray squares (20 to 23) on my Macbeth chart. The numbers correspond to terms like "neutral 8 (.23)".

Is this any relation to how the gray card it specked at 18% gray etc. In other words does any particular patch approximate 18% gray.

My wild guess would be that each increment is roughly a stop or so up from black.

-thanks,
Marquette
