Photoshop features a tool that looks, at first, to be somewhat peculiar. It’s called the Marquee Tool; and when used in its Single Row or Single Column format, it basically drags out photo pixels to create a long line of color.
That doesn’t sound like an ideal tool for editing photos, unless you want yours all to have weird stretches in the middle of them where it looks as though a giant pair of hands have pulled someone’s face apart. However, when you remember that Photoshop works on a basic layering principle, you can start to see the framing benefits of creating what are essentially patterns made out of the primary colors of your photo.
