I am trying to track down some information I **think** I read here a while back, but my googling/searching skills are letting me down.
It was something along the lines of digital exposure / sensors being linear so that whilst you captured lots of data in the highlights you captured less data in the shadows (lots of bits at the top of the line, not so many at the bottom); and this was a common misconception...
Does this mean anything to anyone?
(Background; I am taking a UK digital photography course (NCFE level 2) and trying to delve further into digital photography; and my garbled memory of the above piqued my interest which is why I am trying to track it down...)
