Glossary of Terms
are normally placed on a table or work bench. These models come complete
with mounted baseboard, and feature "front of baseboard
controls." They are more portable than other types, but
maximum enlargement size is restricted by comparison.
is the DeVere cold cathode diffused light source for black and white printing.
Commonly referred to as a "cold light head," it suppresses dust
and negative blemishes.
Loop refers to an
advanced version of the Dichromat colour heads in which the system
automatically detects and corrects for changes in the colour and
intensity of the lamps, and movement of the filters is microprocessor controlled. This system provides highly accurate filtration
settings and maximum print repeatability through lamp changes and when
working from recorded exposure data. The need for fewer test prints
ensures greater productivity.
is the DeVere diffused colour light source featuring fade-free cyan, magenta, and
yellow dichroic filters for subtractive colour printing. Interchangeable
light collecting boxes are available to concentrate light output for
smaller film formats.
a diffusion light source for black and white printing based on the
Dichromat head, producing results similar to the Cathomag cold light
model enlargers are mounted on a base section which contains a drop
table with a baseboard, and feature "front of baseboard
baseboard controls - hand wheels mounted at the front of the
baseboard are used to control elevation and focus. The
controls are always at a convenient position for the operator regardless
of the position of the enlarger head.
enlargers project the image onto a wall or projection board. These
models are principally used for mural size enlargements and run along
track installed on
the floor. Adjustment of enlargement size is accomplished by moving the enlarger closer or further away
from the target area, using the lens movement for small adjustments and
Restricted only by the size of the room and the length of track,
horizontal enlargers thus provide far greater enlargement capability than
to the condenser light source, designed and
manufactured by Rodenstock, for the horizontal enlargers. These
lamphouses utilize four main condenser lenses, with supplementary
lenses available to accommodate formats smaller than 4"x5".
source is a
high intensity focused light source design used for high contrast work such as
microfilm, engineering drawings, electron microscope negatives, Ektalith
is the condenser light source for the vertical enlargers featuring
interchangeable condenser lenses manufactured by Rodenstock. The Varicon lamphouse can be converted to Point Source
configuration by removing the top portion of the head and substituting
the optional point source unit.
feature adjustable dichroic filtration for use with Kodak Polycontrast,
Ilford Multigrade, and other black and white variable contrast papers.
Based on the Dichromat design, they also use tungsten-halogen lamps.
model enlargers are intended to be mounted on a firm wall structure and
project the image to a
freestanding table or moveable roll easel. This system features controls
mounted on the chassis itself, and is advantageous when larger prints
are required than can normally be made with the use of a fixed baseboard
or when multiple paper handling systems are to be used.
