Footnotes

[1]

This claim is based on a combination of response curve of the sensor, properties of the UV-IR cut filter, and the emission spectrum of the light source. These are all off-the-shelf components, and are thus unable to exactly match the response spectrum in the ISO specification. However, they are fairly close, should meet the needs of most use cases involving B&W photographic materials.

[2]

The goal for measurement accuracy is ±0.02D under most circumstances, and ±0.01D under freshly calibrated lab conditions. However, it is difficult to adequately test reflection density beyond 2.00D and transmission density beyond 4.00D due to availability of reference materials.
