n The High indicator determines which intensity value is shown at the maximum value of
the gray scale in the gel image.
n The Low indicator determines which intensity value is shown at the minimum value of
the gray scale in the gel image.
n The Gamma indicator changes the grayscale curve. A value of 1 is linear. A value <1
redistributes a greater proportion of the gray scale to the first half of the intensity
values. A value >1 redistributes a greater proportion of the gray scale to the second
half of the intensity values.
To change the histogram scale
1. Open an image in Image View and tap Transform.
