film density

Because of the film density, film speeds were necessarily slow.

The influence of nanocellulose film density and porosity on film oxygen permeability has recently been explored.

Greyscale/contrast - Filmlook alters the gray scale, color, and contrast to approximate the typical film characteristic - the "film density curve".

For example, film grain is quantified as graininess via a measurement of film density fluctuations as seen through a 0.048 mm sampling aperture.

Because patients vary in size and shape, an AEC device is very useful in achieving good consistent x-ray film densities compared to non AEC x-ray exposures.

Plots of film density (log of opacity) versus the log of exposure are called characteristic curves, Hurter-Driffield curves, H-D curves, HD curves, H & D curves, D-logE curves, or D-logH curves.
