A process and the result of making a composite photograph by cutting, gluing, rearranging and overlapping two or more photographs into a new image. Sometimes the resulting composite image is photographed so that a final image may appear as a seamless photographic print. A similar method, although one that does not use film, is realized today through image-editing software. This latter technique is referred to by professionals as "compositing", and in casual usage is often called "photoshopping" (from the name of the most popular software). A composite of related photographs to extend a view of a single scene or subject would not be labeled as a montage.
Digital painting is a method of creating an art object (painting) digitally and/or a technique for making digital art in the computer. As a method of creating an art object, it adapts traditional painting medium such as acrylic paint, oils, ink, watercolor, etc. and applies the pigment to traditional carriers, such as woven canvas cloth, paper, polyester etc. by means of computer software driving industrial robotic or office machinery (printers). As a technique, it refers to a computer graphics software program that uses a virtual canvas and virtual painting box of brushes, colors and other supplies. The virtual box contains many instruments that do not exist outside the computer, and which give a digital artwork a different look and feel from an artwork that is made the traditional way.
Speed painting is an artistic technique where the artist has a limited time to finish the work. The time can vary, usually a duration is set from several minutes to a few hours. Unlike sketches, speed paintings may be considered "finished" after the time limit is up- it is generally accepted among painters that if a piece is altered after the allotted time, it can no longer be truly considered a speedpainting.
