Toni features twelve grayscale steps, six closely spaced light chips and six similarly closely spaced dark chips, plus two gamma step gray bars. The darkest step is DSC's popular 3-D CaviBlack, which typifies the darkest area in any real scene. |

Uneven lighting top-to-bottom will produce double gamma bars. |
If the budget only allows one grayscale chart, make sure it's a Toni. Not only does Toni let you set white, black and gamma levels, but also the vitally important toe and knee adjustments. Because of differences between cameras these simulated waveform illustrations are theoretical. Cameras will inevitably show compression in the darker steps. Note below how the horizontal gray gamma bars help in lighting the chart evenly. |

A hotspot in the center of the pattern will produce a curved gamma trace. | Here lighting is even and the two horizontal gamma bars fall in a straight line at the same position. |
Toni and other DSC charts are designed to produce familiar electronic displays that are easily interpreted using standard waveform monitors and vectorscopes. In production, a few frames of a Toni along with CamAlign or Combi Grayscale/colorbar shot at the head of a scene provides unequalled color matching and level optimization in post. |  |
