The misrepresentation of detail finer than a sampling system can resolve, appearing as false structure rather than as blur.
Amp Glow
Sensors & Digital Capture
A coloured brightening at one edge or corner of a long exposure, caused by heat and stray light from on-chip electronics.
Analogue Gain
Sensors & Digital Capture
dB or ×
Amplification applied to the sensor's signal before it is digitised, which is the physical mechanism behind ISO settings.
