Low contrast images

A very basic and classic method to hide a message in an image is to write it with nearly the same color as the background. In that way it will be invisible to the eye, unless you for example fill the background with another color. Othen hiding methods are more subtile and require more advanced methods to find the hidden message. A good image editor is a must for a puzzle solver.
