Density
01
densitet
(physics) the degree to which a substance is compacted, measured by dividing its mass by its volume
02
densitet
the spatial property of being crowded together
03
densitet
the amount of light that is allowed to pass through a photographic filter or film, typically measured in stops or optical density units
What is "density"?
In photography, density refers to the degree of light and dark in an image or a photographic print. It describes how much light is absorbed or blocked by the film or paper, affecting the image's contrast and tonal range. Higher density areas appear darker because they have more light absorption, while lower density areas are lighter. Managing density is important for achieving the desired exposure and contrast in photos, ensuring that details are visible and well-balanced throughout the image.

Metropolitan areas typically have higher population densities compared to rural regions.
The city's population density decreases as you travel further inland.
Solar activity influences the density and temperature variations within the thermosphere.
Pool technicians check chlorine solution density with a hydrometer to balance chemical levels for safe swimming.
Understanding densitometry principles is crucial for accurate density measurement.
