Sensors & Digital Capture

Raw Bit Depth

The number of bits used to record each photosite's value in a raw file, determining how many tonal levels are captured.

Levels = 2^bits bits
Sensors & Digital Capture

Raw Data

The minimally processed values read from the sensor, before demosaicing, white balance or tone rendering.

ADU
Sensors & Digital Capture

Read Noise

Noise introduced by the process of reading and digitising the sensor's signal, independent of how much light was captured.

e⁻ (electrons)
Sensors & Digital Capture

Readout Speed

How quickly a sensor's entire array can be transferred off the chip, usually quoted as the time to scan the full frame.

ms
Sensors & Digital Capture

Rolling Shutter Artefact

Distortion caused by a sensor being read out progressively, so different parts of the frame record at slightly different times.
