An educator since the early 1960s, Jerry Uelsmann began assembling his photographs from multiple negatives decades before digital tools like Photoshop were available. Using as many as seven enlargers to expose a single print, his darkroom skills allowed him to create evocative images that combined the realism of photography and the fluidity of our dreams.
