The logo is more my branding that originated back in 1997 when I was working on a stained glass feature while I was in the Swansea Art College (UK). The actual outline has remained faithful (12 pieces of triangular glass with 30/60/90 degree angles) each with extending lengths and separated by leading. The actual colors and shades of grey I developed in 1999, when I adapted the design to my commercial photography business (Mk.1photo). I wanted a logo that exemplified photography at its base (traditional film photography). So I took six of the seven colors of the visible spectrum for one side of the design (depicting color photography), and then six equal shades of monochrome, from black to white (depicting black and white photography), and formed them as a sensitometric step-wedge (the type used in photographic densitometry). These aspects formed my branding logo, and while photography is no longer my main form of media, the design does relate to any form of media I work on in my position as an interactive designer, along with any other form of multimedia experience. Sensitometry is the science of measuring the sensitivity of photographic materials. As a photographer, graphic arts, cameraman, cinematographer, or other user of photographic materials, you will use sensitometry in the control of operations involving exposing and processing photographic materials.
Photographic manufacturers also use sensitometric methods in the control of manufacturing process.
