Viewing, navigating, sampling, and annotating tools in Photoshop

Photoshop has an abundance of tools to help you view and navigate your image window. These tools allow you to zoom in and out, move your image within the window, and measure distances and angles. The Eyedropper and Color Sampler tools let you pick up and sample color respectively — handy for grabbing or evaluating color in an image. The Notes tool and Audio Annotation tool create written and audio notes that you can leave in an image window — useful for collaboration purposes or simply for reminders to yourself.
