1901 Camera Mag. 23 Oct. 14 The idea at the root of the ‘Densitometer’ is that if it is possible to ascertain the density of a negative in a uniform and accurate manner the difficulties of bromide printing are at once overcome.
1955 Gloss. Terms Radiol. (B.S.I.) 54 Densitometer, an instrument for measuring photographic transmission and/or reflection density.
1959 New Scientist 27 Aug. 283/1 The density of photographic emulsions must be accurately controlled in order to achieve the best results in colour printing. Normally this quantity is measured by means of a densitometer which successively views selected points of the image, producing a value for each position.
1961 Printing News 16 Feb. 9 Densitometers—particularly of the reflection type—will not always agree on a numerical value for density.
