Sensitometry
INTRODUCTION
The objective study of the response of imaging systems to light or other radiation is called sensitometry. It is concerned with the measurement of the exposure that a material has received and the amount of the resultant image. Sensitometry in silver-based photography which is the subject of this chapter is assessed by the amount of blackening, silver image formation, which takes place.
