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.
