Cynthia,

Normalized Off is a setting choice of some clinical studies reading centers.  I 
believe it allows them to evaluate the image in a software other than Heyex.

Hi all....

What is the value of performing Spectralis with normalize setting off versus on?

Seems it just digitally compresses the tonal value if the image? When do you 
use one setting versus the other?
