Final answer:
A photomontage is intended to create a single, seamless image through the physical or digital manipulation of multiple photographs.
Step-by-step explanation:
Unlike a photo collage, which is an art technique of assembling different pieces of art into one cohesive piece, a photomontage is made to be a single image. The process of creating a photomontage involves cutting up photos and gluing them to a piece of paper, or using a digital photo program like Adobe Photoshop. This can result in a realistic, seamless photo or in an abstract composition. Moreover, the concept of montage extends into the digital realm, encompassing 3D computer graphics and digital painting, which are also forms of digital artwork where computers and software play a central role.
