The Tone System is a process for color correcting digital images. It incorporates color management and specifically addresses systemizing white point and black point settings for specific printer/media combinations. The use of Precision White and Black Point Parameter Targets allows the photographer to predict the tonal separation in highlights and shadows to a higher degree than with color management alone.
By following the six-step Tone System Color Correction Routine and applying visual evaluation results from the Precision White and Black Point Parameter Targets, photographers and digital printers can achieve more accurate color, richer tonal ranges, and better shadow and highlight detail in their digitally produced images.
In addition to accurate color representation, images processed with the Tone System Color Correction Routine and systemized with Precision White and Black Point Parameter Targets can achieve full scale, full substance tonal rendition.
