Image and graphics editing refers to modifying digital or traditional photographic images and visual representations using techniques and tools. Images from devices like scanners and cameras may be good but not perfect, so image editing is done to improve quality and create the best look according to parameters. While photographs appear realistic, they represent a selective window and manipulation of reality by the photographer. Digital photographers have many editing tools at their disposal to manipulate images from exposure and filters to compositing. Graphics editing uses visual representations alone or combined with text to communicate targeted messages, and can be done using software programs.
