A master platinum printer, Dan was one of the first fine art photographers to champion digital technology by creating the digital negative in 1992. His methods allowed him to embrace the unlimited control of the new Adobe Photoshop and produce a negative from a computer file. His "digital negative" was used to print in the classic darkroom making beautiful handcrafted platinum prints in the early days of digital imaging when printers fell far short of producing fine art quality results. By sharing his pivotal methods, Burkholder has become a unique teacher and mentor for thousands of photographers by bridging the worlds of classic photography with the evolving digital era. He continues to forge ahead into new areas of photography, preaching the fine art potential of the Apple iPhone and the smaller micro 4/3 cameras. His innovations introduced two original darkroom techniques, creating the pigment over platinum print in 2001 and the platinum over gold leaf print in 2007.
