A photometer is used with the enlarger to indicate
average density and exposure. The use of standard development techniques
under normal conditions will allow a viewing of the image. Once
printed and dry-sealed, the paper, together with an instruction
leaflet, is introduced into a protective envelope, which in turn
goes into a sealed, labelled, opaque envelope.
The author makes no selection from the files of films nor needs
to view the contents of the negatives. The strips of negatives are
randomly extracted from the files and all the process is developed
in a semi-automatic way. After the imprint, the negatives are destroyed
and the envelopes are numbered.
