Eric Cahan Filters the Skies

“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,” Eric Cahan has said of his “Sky Series,” including this sky that fades from cobalt to cyan to a vibrant yellow.

But just how exactly does he do it? “The actual process is done with colored resin filters I make myself and hold in front of the lens before I shoot a picture,” he says. “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.”
