Making aEnlargement from
your negative
Making an Enlargement
Part Two:
Correct Exposure:Test Strips & Final Print
Darkroom Knowledge
This PowerPoint is under the assumption
that you have exposed and
developed Photographic Paper
Darkroom Knowledge
You should have already completed part one: Enlarger Set Up
Now for Part Two
You need
50 minutes to do this activity!
You
cannot start it one day… then finish it later
Darkroom Setup
Paper DeveloperIndicator Stop Bath
FixerOrbit Bath
Wash
Pre-DarkroomActivities
Cleaning Negatives…
ONLY with special negative cleaner
and cotton pads !
Pre-DarkroomActivities
NEVER use paper towels to clean your negative… or rub it
on your shirt.
You will scratch the dickens out of your negative.
Quickly Set Up your enlarger to make an enlargement of
your negative.
The size is up to you, but it must be
Portrait Orientation.
Once you are sure of your set-up…..
Don’t move anything !
Close down the f-stop to
2-clicks
The smaller the opening, the better the focus !
Change Timer to the “T” Position
Lamp will turn off and
is now in “timer” mode.
TimerIn the
“T”Position
Set the Timer to
5 seconds
Safe LightsOnly
From here on…
Safe Lights Only !!!
Photo PaperCut to size
For the “test strip”, it does not need to be the full size
of the finished print….
Safe Lights Only !!!
Photo Paper
But make it big enough that it will include important parts of your
photo… like the face !
Safe Lights Only !!!
Photo Paper
You will place it with the EMULSION up on the easel.
(That means “shinny side” up)
Tape Down Photo Paper
Emulsion Up(that means shinny side up)

Begin the Development
Process
The exposure is done.We will now develop the photo paper using the same procedure as we did for the contact print and the PhotoGram !
the Development Process
Developer 2 minutes (constant
agitation)
Stop Bath 20 seconds (constant
agitation)
Fixer 5 minutes
(2 min for test strip)
Orbit Bath 5 minutes
(1 min for test strip)
Wash 5 minutes
(1 min for test strip)
Squeegee
Carefully squeegee off as much water as you can.
One or two passes is all it takes.Be very careful not to scratch
your print.
Under normal lighting, look at your developed test strip…..
Which of the five exposures will you use?
Inspection
If none of the five are usable, you will need to make another
test strip and adjust your exposure times !
Inspection
Which One is Best ?
15 sec is not quite dark enough….
20 sec is too dark
So you decide
on 18 seconds
Show the Test Strip to the teacher.
Discuss with him the exposure time
you will use.
You must get permission from the
teacher before you make the
final print…
Or you will have to redo this project.
Set the Timer to your selected
exposure time
(In this example, we set the timer to 18 seconds ! )
Put some new photo paper into the easel.
It now needs to be the full size of the finished
enlargement
It now needs to be bigger than the
opening in the easel so that you will have a nice white border on all four sides of the enlargement.
Expose the paper for the time selected from your test
strip….
Then develop as normal.
Your Final PrintShould be in Sharp FocusHave full tonal rangeBe free of scratches /dustHave a 1/4” white border
Show your Final Print
To the teacher along with the test strip you made earlier this class period.
Don’t forget to take your Negative !
That’s it !
If you follow directions, you will be quite successful.
One more thing…….
Why can’t I make my test strip on Monday….
Then make my final print on Tuesday ?
The enlargers are all different !
Even if the enlargers look
alike…. The light bulbs are
different ages and usage
The electricity is different every day !
Other people are using that enlarger,
so your magnification will not be consistent.
The chemicals are different
strengths everyday.
The temperature is different everyday.
The warmer it is, the faster the
development process
So…. The test strip must be made the same day & class period as the final
print !
May all of your visits to the darkroom be pleasant and memorable.
