A marquee is a selection tool found in most image editing programs, such as Adobe Photoshop, that allows users to select specific areas of an image. The selected area is highlighted with dotted or "marching ants" lines, and can be shaped as an oval, rectangle, or freehand, depending on the tool's settings.
Understanding the marquee tool is important for photographers, graphic designers, and digital artists who need precise control over editing, cropping, or isolating parts of an image. It enables targeted adjustments, layer manipulation, and creative composition, making it a fundamental tool in digital image editing workflows.
