The TE282 is designed to determine the shading/vignetting of a digital camera. A matt-finish on both sides avoids any kind of reflection. The transparent chart provides a very high transmission. It can be used in combination with an integrating sphere or a light box.
Technical information
Transmission: 84%
When using the TE282 chart with the LE7, a special spectrometer diffuser cap (TE282 add-on) is offered with the chart. The diffuser cap ensures that the measurement by the spectrometer matches to the light emitted by the LE7.
An analysis of the images, taken from this test chart, can be done using our iQ-Analyzer analysis software. The analysis will provide the following results:
- luminance shading (in f-stops, digital values and CIE-L)
- color shading (CIE-C, G-R and G-B; CIE-E_ab)
- visual noise
