- What is a densitometer? It’s an optical instrument used to measure the density (built in darkness) of photographic film and paper. Without one, objective evaluation is quite difficult. You position the material between the light source in the head of the device and the photoelectric cell in the base to achieve a reading.

- densitometer, device that measures the density, or the degree of darkening, of a photographic film or plate by recording photometrically its transparency (fraction of incident light transmitted). In visual methods, two beams of equal intensity are used.

- The other photo densitometer that looks promising to me for hobbyist use is the Eseco Speedmaster SM-10T. Made in Oklahoma by a going concern noted for good customer service, the SM-10T is a simple-to-use and robust little device that sells new for $1085, which is very reasonable as new densitometers go.

- A pressroom densitometer or spectrodensitometer measures ink density on a color bar, providing feedback to the press operator as to how to adjust ink levels should density readings be too high or low. Proper density values are checked in each ink zone using a color bar or other areas of solid single-color ink.

- Densitometry comes into its own in color photography. Status A, M and D are designed with color in mind, the filter sets being used for various films and papers. There are filter sets for negative films, reversal films, and papers. There are sets for B&W and etc..

- To calibrate any transmission densitometer you need a calibrated step tablet. A strip of film with 21 steps of density and a data sheet that states the density of each step. The densitometer you purchase will include such a strip. You can buy a Step Tablet # 2 from Kodak. The steps are 0.15 density units apart. alan_marcus|2, Jul 4, 2009 #1

- Film photography is interesting hobby; sometime you wonder where to use a densitometer and then in next picture one is actually designing one and measuring with it. Oh well.. So I build one. A DIY densitometer, currently working only on film so no reflective light measurement - altough I have prepared for it in the parts.

- To make a long story short, for transmission densitometry (reading densities of negatives), the densitometer reading is a measure of the opacity of the film. The higher the number, the more dense the film, and the more light it blocks. Low numbers would be relatively clear (shadow areas) and high numbers would be relatively dense (highlight areas).

- Densitometers There are two types of densitometer: visual and photoelectric. Visual densitometers use the eye to compare a known density sample with an unknown density sample. You simply move a density wedge until its density looks like your sample. The density is then found by looking at the scale on the known density sample.
