A file of digital color data representing a color image is transformed into a new file of digital color data where one or more colors have been transformed to one or more new color locations where their reproduction is known to be preferred. Various components of a particle control system can include a tunnel circulation and filtration system that can be in flow communication with bridge circulation and filtration system. For each selected pixel a first light intensity of the pixel resulting from a first illumination of the object and a second light intensity resulting from a second illumination of the object are calculated. The compounds can be used to deposit metal-containing layers using vapor deposition methods.
