Introduction
Once you've developed your first black and
white film, you'll want to make a print. This document will guide you
through the steps to produce a contact print, so you can assess your negatives
and decide which ones are the best, and how to make an enlargement of
a negative to hang on your wall. To do any printing you will need some
processed lack and white negatives and some black and white photographic
paper.
Preparation
Pour Paper Developer, Stop Bath and Paper
Fixer into trays and place them so that the Fixer is closest to the sink,
next the Stop Bath and finally the Developer. This way, the trays are
in the correct order to move from the enlarger to the water where the
final print will be finished. You do not need to empty the bottles entirely,
just enough so that there is about a 1cm depth in the tray.
Switch on the red safelight and switch off
the main lights. All printing must be done under the red safelight. Switch
on and adjust the enlarger height and focus so that light covers the baseboard.
Be careful as some enlargers have locking devices. On the lens of the
enlarger there is a collar with numbers on it. Turn the collar so that
you have the brightest light falling on the baseboard. Now turn it two
clicks dimmer. Finally put a number 3 filter in the filter holder.
Making a Contact Sheet
- If you haven't cut your negative yet,
cut them so that there are 6 to a strip. Open the Contact Printer (Hinged
piece of plastic with a glass front) and place each strip in the pockets
on the glass so the emulsion side (the non-shiny side) is face up, and
the shiny side is touching the glass.
- Place the Contact Printer on the baseboard,
glass side uppermost. Making sure the enlarger is off, take a piece
of photographic paper out from the box/bag. Cut it into strips using
the guillotine or scissors. Now place the paper shiny side up under
a strip of negatives in the contact printer. Close the printer and make
sure the paper box is closed.
- Adjust the enlarger timer so it is set
to 5 seconds. Hold your paper box/envelope over the paper so that only
(roughly) one negative is uncovered. Switch the enlarger on for 5 seconds
so that one negative gets 5 seconds of exposure. Now uncover one more
negative and switch the enlarger on for another 5 seconds. Continue
in this manner until the entire piece of paper has been uncovered and
exposed.
- The last end of the paper to be uncovered
has only been exposed for 5 seconds. The section adjacent to it has
been exposed for 10 seconds and so on.
- (*)Place the exposed paper in the
Developer for 1 minute. Agitate the developer occassionally by lifting
one edge of the tray. You should notice the image forming on the paper.
- Pick the paper up with tongs and let it
drip over the developer before placing it in the Stop Bath for 30 seconds,
agitating occassionally.
- Let it drip over the Stop Bath before
placing it in the Fixer for 2 minutes, again with agitation.
- Finally place it in the sink and wash
with water. This development process, from developer to wash is standard
no matter what you are doing, so it is worth remembering the times.
- After checking that no photographic paper
is open (otherwise it will get exposed), switch on the lights and look
at the paper. The paper should go from almost white to black, The near
white end is where the paper got 5 seconds of light, the darkest when
it got 30 seconds (6 negatives times 5 seconds).
- Decide which section has the best tones
(this is purely subjective, but it should have some pure white and some
pure black in the image). The spaces between the individual negatives
in a strip should just be pure black.
- Work out the time that it was exposed
for by counting the number of negatives from the lightest end and multiplying
by 5. If the teststrip is either far too light or too dark, do another
teststrip, opening the lens aperture one click brighter or one click
dimmer respectively.
- Now place an entire sheet of paper under
the Contact Printer and expose for the amount of time you found above.
Put in the developer, stop bath and fixer (see *). Wash the contact
print for 6 minutes, then hang it up to dry with a clothes peg.
Making a print
Now we have a positive copy of our negatives
from which we can select what to print. Choose the best shot from the
Contact Print, and locate the negative (remember to remove the negatives
from the contact printer and keep them in negative sheets for safe keeping).
- Take the negative carrier from the enlarger
and put the negative in emulsion side down (shiny side up). Carefully
put the carrier back into the enlarger.
- Set the enlarging easel (metal contraption
with rulers attached) to just under the dimensions of your paper (usually
8x10" or 5x7").
- Place the easel on the baseboard. Adjust
the enlarger height and focus so that the negative (or whichever part
of the negative you wish to enlarge) is in focus at the right size on
the easel. This may take some fiddling as the magnification changes
with focussing. Do this part with the lens fully open (ie brightest
image you can get by moving the ring on the lens).
- Set the lens two 'clicks' down from brightest,
and put a number 3 filter in the holder.
- Now make a teststrip as you did for the
contact sheet, exposing a strip of paper one bit at a time on the easel
(you don't need the contact printer for this). Develop the paper as
in *.
- Once you have developed the piece of paper,
look at it under normal light and determine the correct exposure time.
If all the sections are too light, open up the lens one click brighter
and try again. If too dark, close the lens up one click dimmer.
- Now you are ready to make a complete print.
From the test strip you should be able to work out what the correct
exposure for the negative is, by counting the sections from the lightest
end and multiplying by 5 (or whatever interval you used).
- Place a piece of paper in the easel and
expose it for the correct length of time by changing the timer.
- Develop the piece of paper as normal (see
*). Leave it under the tap for 10 minutes to wash away all the chemicals.
- Let the print dry and congratulate yourself
on your photographic ability.
Moving on
If you aren't happy with the print you can
control it by changing the contrast filter. By changing the filter from
3 to 4, the resulting print will have more contrast, more of the print
will be near white or near black and less a meduim gey. By changing the
filter down to 2, the print will have more grey and less pure black and
white. Try both to get a feel for how changing the contrast can affect
your image. Remember to do a test print when you change the filter.
Try experimenting by covering some of the
paper with you hand during part of the exposure. The areas you cover up
for part of the exposure will end up lighter. If you cover up almost all
of the image, the effect will be that the bit not covered up is darker.
You don't have to print the entire negative.
Instead, try only printing the most interesting part of it, while keeping
the print size as large as possible.
