This photo is much more unusual than it seems at first glance. Though the end product is in colour, it was actually shot with black and white film. (Fuji Acros 100, for the curious.) The photo was captured three times, each time with a different coloured filter on the lens: red, green, and blue. Those images were then scanned and digitally composited, resulting in the photo you see here.
The process is painstaking and requires many hours of careful retouching in order to perfectly align the three negatives and reduce colour fringing caused by microscopic distortions in the original film, but the end result has a quality rather unlike any colour film on the market today – to my eyes, it most resembles Kodachrome. Unquestionably worth the extra effort required.
