Keith studied photography while at Oxford University and put himself through law school with wedding photography and black & white portraiture, as well as selling his photographs in art shows and fine restaurants.  After many years using a smaller format and shooting color transparencies along with black & white, Keith began working exclusively in medium format in 1996 for the higher quality yielded by larger negatives.

In 2008, Keith began the shift to digital and now works with a professional Nikon camera system, develops the resulting images with Adobe Photoshop Lightroom, and prints with a massive Epson 24" printer. All of his serious work remains in black & white, without digital manipulation and development only to show reality.

Keith has exhibited his prints in numerous exhibitions, including multiple single-artist shows in Washington, D.C. and Kansas City.
