List and briefly describe at least three general guidelines for editing a photo.

What will be an ideal response?

Choose the correct tool. When you need to copy and paste portions of your photo, consider carefully which Photoshop selection tool to use. You want the procedure to be efficient and produce a clear image. Keep in mind the shape and background of the photo you want to copy, as well as your expertise with various tools.Plan your duplications. Use a storyboard or make a list of the items you plan to duplicate. Then decide whether it will be an exact duplication or a manipulated one, called a transformed copy. The decision depends on the visual effect you want to achieve and the customer requirements.Use grids and guides. When you are working with exact measurements, close cropping and moving, or just want to align things easily, use grids and guides to display nonprinting lines across the document window. Use the Photoshop snapping function to align selections. Visual estimations of size and location are easier to perceive when using these guides.Create files in portable formats. You might have to distribute your artwork in a variety of formats, depending on its use. Portability is an important consideration. It usually is safe to begin work in the Photoshop PSD format and then use the Save As command or Print command to convert your work to the PDF format. PDF files are platform and software independent.
