This means that the 35 mm frame is 1.5, 1.6, or 2 times the size of the digital sensor.
In recent years the focus has been on motion capture, for which actors are wired with tiny digital sensors.
This article describes the difference and the reason for the development of digital sensors.
There are two big benefits of digital sensors over film stock.
Many digital sensors have less dynamic range than color print film.
Some have a different coating formula which is optimized for digital sensors.
The telescope has not been upgraded with a digital sensor.
The key to taking a good action photo doesn't hinge on whether the shot was taken on film or by a digital sensor.
When a picture is taken, the mirror flips out of the way, and the light instead hits the imaging surface (film or digital sensor).
The camera will contain 30 digital light sensors called charge-coupled devices.
