Cahan himself made most of the work for his current project, Sky Series, during his extensive travels. Each photograph and sculpture is titled with the time and location of its conception. In this way, Cahan catalogues his visual journal. “ During my travels, I discover what I want to document. My works are titled to remind me of the experience, both visually and spiritually.” Cahan’s viewers see in his work his unique interpretation of a specific time and place.
Understanding what inspires Cahan and learning more about the elaborate technical process necessary to create his pieces leads to awed appreciation of his art. When asked how much post-production goes into creating the final piece Cahan laments, a lot of people ask me if this is all done in Photoshop. In fact, very little Photoshop is used. I will only tone photos to match the paper type and, in some cases, add a bit of color curves. The actual process is done with colored resin filters I make myself and hold in front of the lens before I shoot a picture. When a color filter is used against a blue sky, it always alters the color of the sky. I know the colors I am trying to conjure and choose the filter accordingly. Many factors affect the capturing and manipulating of light and shadow, which is why Cahan works at sunrise and sunset and also, invariably, at the water’s edge: “My mission is to capture light. Light is the true subject of this series: its constant mystery, the way it shifts and colors everything around it in nature.”
