black & white previews
All colour images are also available as black & white prints. The b&w previews offered here are produced by simply desaturating the image via Javascript. The result is a neutral b&w preview which may appear flat or too dark/bright. Before printing, however, each image is individually assessed and adjusted for best contrast, tonal quality, and dynamic range.
