A 2D image, or two-dimensional image, is a flat representation of visual information that has height and width but no depth. Common examples include photographs, drawings, and digital graphics. These images can be created using various techniques, such as painting or photography, and are often displayed on screens or printed on paper. 2D images are widely used in many fields, including art, design, and communication. They can convey information, evoke emotions, or serve as decorative elements. Technologies like Adobe Photoshop and Illustrator are popular tools for creating and editing 2D images, allowing artists and designers to manipulate visual content easily.
