In Intermediate, we learn how to use the camera’s settings to get good negatives.

It can be a little complicated and tricky at first, but this should make your life WAY easier in the darkroom.

What happened in Beginning?

What happened in Beginning?

You used a point-and-shoot camera, or a camera set on Auto, to take pictures

Some of your negatives were dark, or dense, others light

You HAD to make at least one test strip before each print, because many prints requires many different amounts of light to make a good picture

In the darkroom, you make a test strip to determine the perfect amount of light to make a good print, with blacks, whites, and grays in between.

In the camera, there is also a perfect amount of light to make a good negative.

Cameras on automatic are often “guessing” what that right amount of light is.

Some cameras are better guessers than others.

Perhaps in beginning, you had some of each of these types

of negatives on a contact sheet.

An under-exposed negative happens when the film doesn’t get enough light (like when you shoot your film indoors).

You probably needed to use a high

filter to make a good print.

An over-exposed negative happens when the film gets too much light.

You probably had to make your lens really bright, and use lots of clicks to

get a good print.

In Intermediate, we will learn how to make the negative on the right, and save you time and effort in the darkroom!

ExposureExposure Exposure means the amount of

light that hits the film when you press the button- the shutter button.

Exposure means the amount of light that hits the film when you press the button- the shutter button.

ExposureExposureThere are 2 things that control the

amount of light that hits the film-

The aperture, or opening of the lens

The shutter speed, or the amount of time the little curtain protecting your film opens for.

The aperture refers to how wide the lens is open. Each of the numbers below the opening represents that size aperture.

Each number on the shutter speed dial represents the denominator of a fraction of a second.2000 is 1/2000 of a second4 is 1/4 of a second1 is a whole second

Shutter Speeds also control motion, or how blurry the picture is. We’ll get to that later!

Getting the exposure right

Aperture and Shutter Speed must work together!

To get a good negative, you must adjust your settings for the type of

light in which you are photographing.
