One of the most popular - and oldest - styles of collage is photomontage collage work. This entails gluing various elements cut out from photos to create a new image. Often, the composite was then photographed so that it became one single image. Nowadays, we can use software to easily do the same thing. Decoupage is another type of popular collage that requires pasting the same image in layers to give it depth and then applying it to an object. Collages can also be made of wood, using pieces of found wood as well as wood shavings. However, some argue that this takes away from the inherent political message embedded in most collage artworks due to the use of contemporaneous clips from magazines and newspapers. However, they are still technically regarded as collage artworks.
