Vignetting by channel
| Left side : The graph shows the radial vignetting profile, normalized to 1 at the vignetting center. The background colored area shows the interval between the min profile (lower limit) and the max profile (upper limit). Right side : This map displays the fall-off percentage across the field. The color coding scale is shown below the map. The Max fall-off value is displayed in bold font under the scale. |

Colored fall-Off profile
| This graph displays the following ratio profiles : | |
| : RED fall-off / Luminance fall-off | |
| : GREEN fall-off / Luminance fall-off | |
| : BLUE fall-off / Luminance fall-off | |

| This map represents the colored vignetting; For a better visualization, the ab components in CIELab 1931 color space have been amplified 4 times. The contour plots indicate specific levels of Δab (=√aČ+bČ). |
