Answer ( Focus within the Depth of Field )
defined as the nearest distance, in which a lens is focused at infinity with a given particular diaphragm opening which will give the maximum depth of field.
Answer ( The Hyperfocal Distance )
Through the range finders, the image of the object appears cut into halves and separated from each other by a straight line, when the lens is not in focused.

Hardening Agent
The process of reproduction. Exposed silver halides are reduced into metallic silver.
Development
