- Print This tab displays the print performance measurement values and graph derived from a RAW image after a normalization step that transforms all images, regardless of original resolution, to an 8Mpix image. The print size we have chosen is a standard 300dpi 8"x12" format, which corresponds to about the physical size of an 8Mpix image printed at 100% magnification.
- Screen This tab shows the measurement values and graph derived directly from a RAW image when displayed on a computer screen at 100% magnification (i.e., one image pixel corresponding to one screen pixel).

- CIE-D50 This tab shows the measurement values and graphs performed under CIE-D50 illuminant. This illuminant corresponds to a theoretical light source matching daylight spectrum.
- CIE-A This tab shows the measurement values and graphs performed under CIE-A illuminant. This illuminant corresponds to a theoretical light source matching a tungsten light bulb.
