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.
