Dear All,

 

I think I must have missed an update somewhere. Usually, if I want to
measure intensity of RGB images, I have to change them to grayscale
first (8bit) but it seems that I don't need to include this extra step
now. I seem to get the same results whether I change my green image to
grey or not. Is this correct?

 

Cheers,

 

Jacqui
