What would be the result of adding a positive constant (scalar) to a monochrome image?

What would be the result of multiplying a monochrome image by a positive constant less than 1.0?

$Close all open figures and clear all workspace variables.
SUse immultiply to dynamically scale the moon image also adding a constant to each
pixel to see the difference.

SWhen dynamically scaling the moon image, why did the dark regions around the moon
not become brighter as in the normally adjusted image?
