Jerry Uelsmann pioneered the art of photomontage (a single composite image comprised of multiple photographs) decades before Photoshop arrived on the scene in February 1990.
He worked with multiple enlargers to create surreal images, some of which contain Jungian archetypes and other dream-style images that speak to the subconscious.
Here are some of my favorites of his works. Our high school photography teacher had shared his work around 2004-2005 and the images left a such a big impression on my that I made my own photomontages in 2008 for my college capstone project and then continued making more for a few years after finishing the photography degree.
