Description
Here is the same set up of the Macbeth Color Chart and the 2 Kodak 18% Gray cards. As can be seen, the smaller gray card is s slightly different shade or color of the larger one underneath. This was captured at 1:15 pm, direct sunlight. Here's what Photoshop's White Balance tool sees for the smaller gray card:
Red = 133
Green = 134
Blue = 137
The larger gray card shows up like this:
R = 135
G = 136
B = 135
So in theory, the larger Kodak 18% Gray card is more accurate, but really splitting hairs and could be my Canon Sensor too.
By the way, the white board in the background, is a sheet of Foamcore and had these numbers:
R = 235
G = 235
B = 235
While the Macbeth white space had these:
R = 235
G = 234
B = 233
