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.
