Reflection density is defined as the log of the reciprocal of reflection: reection
density reection fl fl log = 1 Consider several examples. If the reflected light
intensity equals the incident light intensity then the reflection density is log(1/1) =
0.

Introduction to Color Imaging Science
(15.2) In the literature, the terms reflection density and optical density are also
frequently used to mean either the reflectance density or the reflectance factor
density. Since an exact specification of any density measurement has to include
the ...
In Figure 13.3, curve t shows the spectral transmission density of a magenta dye;
curve p shows the spectral reflection density of the same dye when in a gelatin
layer in optical contact with paper; curve t shows curve t multiplied by a constant ...

Digital Color Management: Encoding Solutions
The dye characteristics are expressed in terms of spectral reflection density,
which is the negative logarithm of spectral reflectance. Reflection density values,
rather than reflectance values, are used here and throughout this discussion ...

The Reproduction of Colour
At low densities, multiple internal reflections cause reflection density to increase
rapidly with transmission density; at medium densities, multiple internal
reflections become progressively less important as the density increases, so that
the rate ...
Reflection. Density. In measuring the blackness of a photographic print, the term
reflection density is often encountered. This is a somewhat specialized concept,
since the glossy surface of many types of photographic paper tends to reflect light

Radiometry and Photometry
It is much more common, because it is useful, to use the term “relative reflection
density” for measurements of reflection density using unexposed but processed
photographic paper or blank printing paper as a reference standard instead of ...
