Digital Art Composites
A composite combines two (or more) photographs to create one final image. With the advent of digital photography, digital editing, and an ever-expanding set of features and tools available, an infinite number of possibilities are available. This technique could be considered to be a new form of collage, using a computer with digital images and effects as opposed to paper and other materials.
Each of these images was created in Photoshop and has multiple photos with dozens of layers; combined with multiple airbrushing and other special effects, to create an entirely new image.
