Dynamic reach is estimated on a scale from 0.0 (wonderful white) to 4.0 (amazing dark), and the single number related with a scanner shows the amount of that range it can differentiate. The base and most extreme thickness esteems that can be caught by a scanner are called Dmin and Dmax, separately. On the off chance that a scanner's Dmin was 0.2 and its Dmax was 3.0, its dynamic reach would be 2.8.

While dynamic reach is a term frequently quibbled about, in truth the spec is more significant for film scanners used to check slides, negatives, and transparencies - - as these kinds of media have a more extensive scope of tones contrasted with photographs, and for which a scanner's higher unique reach can have an effect.
