Photography 1
PROJECT 2: Exposure Triangle, using Manual Mode
LEARNING TARGETS:
1 Students will shoot in manual mode and become familiar with the settings and buttons on a DSLR camera.
2. Students will study the exposure Triangle and how ISO, Shutter Speed and Exposure relate to each other.
3. Students will learn how to manually adjust ISO, Shutter Speed and Aperture on a DSLR camera.

Three Tips to Master Exposure Technically and Creatively by “SLR Lounge” on You Tube.
What is exposure?
In the simplest terms, “exposure is the total amount of light allowed to fall on the photographic medium during the
process of taking a photograph” (Wikipedia).
The amount of light that hits the sensor depends on…
1.) APERTURE The size of the opening in the lens that the light passes through.
2.) SHUTTER SPEED The length of time that the sensor is exposed to light through the shutter.
3.) ISO The sensitivity of the sensor to light.
These three elements make up the “Exposure Triangle”.
ASSIGNMENT:
Most important, put your camera in Manual Mode! Pick a subject to focus on for all the steps of this exposure
study. It could an object, plate of food, flower or a person. Just make sure if you pick a person it is someone who can
stay still and cooperate while you work on your settings. Follow the steps on the next page and take notes as you
shoot. You’ll need to look at the light meter to determine correct exposure. Your exposure setting (light meter) on
the camera will need to be on zero for correct exposure before you take each photo.

DSLR Digital Exposure Triangle
Outdoors Experiment. Shoot while it is light out. Arrange your subject with a visually pleasing background.
Don’t move the angle or viewpoint of the camera for each set of images. It’s important that you keep the
position of your camera in the same spot for each step.
APERTURE Adjustments & Notes:
1.
Set your ISO setting to 400, Set your Shutter Speed to 125 th of a second (1/125)
2.
Now make adjustments to your Aperture until you get the correct exposure. This number will vary
depending on the amount of light available.
3.
Photo #1: What is your Aperture setting? Write it here:
4.
Keep your camera pointing to the same spot and ISO setting at 400, Change your Shutter Speed at 500th of
a second (1/250) this adjustment reduces the amount of light coming into the camera.
5.
Now make adjustments to your Aperture to get the correct exposure again.
6.
Photo #2: What is your Aperture setting now? Write it here:
7.
Re-set your ISO setting to 800, keep your Shutter Speed at 500th of a second (1/500). This doubles the light
sensitivity of your camera.
8.
Once again make adjustments to your Aperture to get the correct exposure.
9.
Photo #3: What is your Aperture setting? Write it here:
SHUTTER Adjustments & Notes
1.
Stay in the same position, camera pointed to the same spot. Set your ISO setting to 100, Set your Aperture
to f/ 5.6
2.
Now make adjustments to your Shutter Speed until you get the correct exposure. This number will vary
depending on the amount of light available.
3.
Photo #4: What is your Shutter Speed setting? Write it here:
4.
Keep your ISO setting at 100 and change your Aperture to f/ 11 this reduces the amount of light coming
into the camera; you will need a slower shutter speed to keep the correct exposure. It may be so slow that
your photo will be blurry without a tripod.
5.
Now make adjustments to your Shutter Speed to get the correct exposure again.
6.
Photo #5: What is your Shutter Speed? Write it here:
7.
Same spot, same camera frame. Re-Set your ISO setting to 800 which increases the amount of light
sensitivity in your camera by three times.
8.
Keep your Aperture on f/11, now make adjustments to your Shutter Speed to get the correct exposure. Most
likely you will now be able to get a sharp photo while hand holding.
9.
Photo #6: What is your Shutter Speed? Write it here:

10. Change your Aperture to f/4 this increase the light coming into the camera.
11. Make adjustments to your Shutter Speed to correct for the extra light.
12. Photo #7: What is your Shutter Speed? Write it here:
ISO Adjustments & Notes
1.
Now move to a new spot / new frame. Set your Aperture to f/ 3.5 and set your Shutter Speed to 125th of a
second (1/125th)
2.
Now make adjustments to your ISO speed only until you get the correct exposure. This number will vary
depending on the amount of light available.
3.
Photo #8: What is your ISO setting? Write it here:
4.
Change your Shutter Speed at 250th of a second (1/250th) Now change your Aperture to f/ 8 this reduces the
amount of light coming into the camera; you will need a higher ISO to avoid a dark under exposed image.
5.
Now make adjustments to your ISO to get the correct exposure again.
6.
Photo #9: What is your ISO? Write it here:
7.
Keep your Aperture on f/8, Now make your Shutter Speed to 1000th of a second (1/1000th) this reduces the
amount of light coming into the camera; again you will need an even higher ISO to avoid a dark under
exposed image.
8.
Now make adjustments to your ISO to get the correct exposure.
9.
Photo #10: What is your ISO? Write it here:
10. Now step inside into darker light. Keep your Aperture at f/8. Change your Shutter Speed to 250th of second
(1/250th) now make adjustments to your ISO to adjust to the lower light inside for correct exposure.
11. Photo #11: What is your ISO? Write it here:
12. Now re-set your Aperture to f/3.5 and set your Shutter Speed to 60th of a second (1/60 th)
13. Now make adjustments to your ISO speed, lowering your speed until you get the correct exposure inside. The
lower ISO will allow for better image quality.
14. Photo #12: What is your ISO? Write it here:
