white saturation การใช้

The face image on the Shroud instead has grey tonalities that vary in the same values field ( between 60 and 256 ), but the white saturation is much less marked and the histogram is practically flat in correspondence of the intermediate grey levels ( levels included between 160 and 200 ).
According to Fanti and Moroni, after comparing the histograms of 256 different grey levels, it was found that the image obtained with a bas-relief has grey values included between 60 and 256 levels, but it is much contrasted with wide areas of white saturation ( levels included between 245 and 256 ) and lacks of intermediate grey levels ( levels included between 160 and 200 ).
