Meaning and Definition

A technical term in photography, reprography, and imaging that quantifies the darkness or opacity of a photographic image or print, as measured by its ability to reflect light.

While primarily a technical term, it can be used metaphorically to describe the intensity or depth of a represented image, idea, or memory.

FAQ

Frequently Asked Questions

They are closely related. 'Reflection density' is a specific type of optical density measurement taken from light reflected off an opaque surface (like a print), whereas 'optical density' can also refer to transmission density measured through a transparent medium (like film).

It is highly unlikely and not recommended. In everyday contexts, simpler terms like 'how dark the print is' or 'the quality of the black' would be more appropriate and understood.

A reflection densitometer is the specialised instrument used to measure reflection density.

A higher reflection density value indicates a darker, less reflective (more dense) area of an image. A perfect reflector (white) would have a reflection density of 0.0.

A technical term in photography, reprography, and imaging that quantifies the darkness or opacity of a photographic image or print, as measured by its ability to reflect light.

Reflection density is usually formal, technical, scientific in register.

Reflection density: in British English it is pronounced /rɪˈflɛkʃən ˈdɛnsɪti/, and in American English it is pronounced /rəˈflɛkʃən ˈdɛnsəti/. Tap the audio buttons above to hear it.
