Darkroom Knowledge

This PowerPoint is under the assumption that you have exposed and developed Photographic PaperDarkroom 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 BathFixerOrbit BathWashPre-DarkroomActivities

Cleaning NegativesONLY 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..Dont move anything !

Close down the f-stop to 2-clicksThe 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 TPosition

Set the Timer to 5 seconds

Safe LightsOnly

From here onSafe 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)

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 !InspectionWhich 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 PrintTo the teacher along with the test strip you made earlier this class period.

Dont forget to take your Negative !

Thats it !

If you follow directions, you will be quite successful.One more thing.Why cant 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.
