RAD 120 Ch 26: Image Receptor
Exposure with verified answers
photographic
Image receptor exposure and contrast are the two ___ qualities that comprise visibility of detail
density
the overall blackening of the film
brightness
a monitor control function that can change the lightness and darkness of an image.
leveling
Window ___ describes digital post-processing that produces changes in birghtness.
quantum mottle; quantum noise
___ ___ is a lack of sufficient incoming data to process an image; also known as ___ ___.
increase mAs
When an image displays mottling or noise, the solution is to ______.
, True (digital)
True/False
With digital systems, mAs is no longer the controlling factor of IR exposure- although it does
play a critical part in determining proper IR exposure.
30%
with film, the minimum change necessary to cause a visible shift in density is about ___
directly proportional
The relationship between mAs and IR exposure is ____ ____
50%
As a general rule of thumb for MAs changes is to make adjustments in increments of ____
True (image)
True/False
As a general rule- if the image requires at least doubling or halving the exposure, it requires
repeating.
quantity; quality
