# Getting 16 bit image statistics in Photoshop

The histogram in Photoshop for a 16-bit image downsamples to 8 bits, showing a tonal range of 0 to 255. I appreciate to show tonal ranges for a 16 bit image a horizontal zoom function would be necessary.

However the mean, std deviation,... statistics also get downsampled to 8 bits with a corresponding loss of accuracy.

Is there a way of seeing the true mean, std deviation etc of a 16 bit image?

img=double(imread('image.png'));
