When you come back to another shot from this errant tape, you would call up the memorized setting and it would correct the color etc. in one stroke. Elsewhere on this website we'll address the art of matching studio TV cameras, in theory and in practice. Chips won, and for probably the same reasons, DSP is taking over camera technology. Meanwhile, camera setup parameters can be set without knobtwiddling or screwdrivers, and then digitally stored, for later recall. Permits excellent picture quality.
Control is consistent and drift free.
Fewer moving and organic components improves reliability. Fewer organic parts results in a smaller, lighter, more power stingy package. Settings can be memorized and accurately recalled. Digital components are less affected by shock, temperature, humidity, pollution, and vibration than their analog counterparts. Matched cameras can be maintained with little technical help.
