LESSON 2
(8) After completing the necessary test and corrections, you should
be able to make good contact sheets.
c. The procedure for making contact prints, using a printer such as the
EN-22A, is quite different from that described in paragraphs a and b.
Listed below are the steps involved when using a contact printer.
(1) Clean the printing area.
(2) Connect the timer to the printer and
then to the proper
Place all the printing light switches
in the ON position.
Check the viewlights and the safelights in the printer
for proper operation.
Place the master switch in the OFF position and check
the operation of the
platen-actuated pushbutton switch.
(3) Clean the negative(s) to be printed.
(4) Place the negative(s) with the emulsion side up on the glass of
the printer.
(5) Turn off all white room lights.
(6) Judge the contrast of the negative.
(7) Select the proper filter and you will be ready to make a test
strip.
d. The procedure for making a test strip is as follows:
(1) If you are making a contact of only one negative such as a 4- x
5-inch, then cut a sheet of paper into test strips approximately 2 inches
wide.
(2) Choose the area of the negative to be used for exposing the test
strips. The area for the test should contain highlights, middle tones, and
shadows.
The same part of the negative should be used to make each test
strip.
(3) Make a series of test exposures using a normal contrast filter.
Use a systematic method of exposing.
For example, you can start with 2
seconds and double it each time, or another method is to expose each test
with an equal amount of increase. The idea here is to bracket the correct
exposure; that is, to go from underexposure to overexposure.
(4) Inspect the test strips and determine the best exposure.
(5) When the best
exposure
has
been
selected,
determine
if
the
correct contrast exists.
