I've been working on trailers for my books recently, and have learned about color, balance, light, dark, mood, and so much more. One thing was to look for the "rule of threes" which is to divide the picture into thirds diagonally, vertically, or horizontally. Certain things lend themselves to this. For example, a photo of a beach. 1/3 is sand, 1/3 is water, and 1/3 is sky. Place a few sailboats in the picture and you create a pleasing landscape. Today, I'm sharing 13 ways to pick a good picture. In order to make it fun, I'm using pix of hunks. (Ah... now you're paying attention!) You'll notice how evident this "rule of threes" is after you begin to look for it.
Quick note: clicking on the pictures will open them in a new window in a larger size so you can see more detail.
