Description 

The aluminum stepwedge is the standard tool for evaluating the dynamic range (latitude) of a digital or film-screen imaging system. This wedge provides 11 steps in 3.2 mm increments. The number of distinguishable steps represents the dynamic range of the system. Images may be evaluated visually or by using a densitometer. The Gammex 117 Stepwedge provides a useful means of comparing the characteristic curve of various film/screen combinations, mAs reciprocity, and if done very carefully, sensitometry.

 

Note: To increase accuracy when evaluating filmscreen systems, a sensitometric pattern should be placed on the film immediately before processing
