Using A Densitometer; Density - AGFA SelectSet Avantra Series Operating Manual

Using a Densitometer

Use a densitometer to measure density and determine optimum
exposure.
Note: Make sure that you know how to use your densitometer
before you begin the evaluation procedure.

Density

Density is the darkness of a photographic image. It is expressed as a
number. The higher the number, the darker the image.
The density of photographic images is affected by:
Exposure
The amount of light that reaches the photographic medium.
Changing the exposure changes the density of the processed
image.
Development
Changes to the developing conditions (i.e., processor speed,
developer temperature) affect the density of the processed image.
Dmax is the maximum density that can be found in a photographic
image.
