Phototools 1 Pro Edition - Full PhotoTools Professional Edition allows you to combine and stack effects very similar to how you would stack layers in Photoshop. This gives you a tremendous amount of creative control and flexibility while you create your own signature look. You even have control over the strength of each individual effect within a stack so if you don't like the default settings of an effect on your image, you can dial it down to better suit your individual photo.
