LA – Exposure Basics – Week 09

After reading the appropriate section in your prescribed textbook From Snapshots to Great Shots, please answer the following questions:

• Name all the functions / buttons of your camera:

• 

• 

• 

• Explain how you would set the correct ISO

1. Activate the camera by lightly pressing the shutter realease button
2. Press the ISO button on the top of the camera.
3. Use the Main Dial to select an ISO between 100-6400.
4. Lightly press the shutter realease button or press the ISO button again to lock in your change.

You can also change the ISO following the same steps while looking through the view finder.

• Explain how you would change the aperture

1. Turn your camera on and then turn the Mode dial to aligne the AV witht he indicator line
2. Select your ISO by pressing the ISO button ont he top of the camera, and then turning the Main dial.
3. Point the camera at your subject and then activate the camera meter by depressing the shutter halfway.
4. View the exposure information in the bottom area of the viewfineder or by looking at the rear display panel.
5. While the meter is activated, use your index finger to roll the Main dial left and right to see the changed exposure values. Roll the dial to the right for a smaller aperture (higher f-stop number) and to the left for a larger aperture (smaller f-stop number).

• Explain how you would change the shutter speed

1. Turn the Mode dial to align the M with the indicator line.
2. Select your ISO by pressing the ISO button on the top of the camera, and then turning the Main dial.
3. Point the camera at your subject and then activate the camera meter by depressing the shutter button halfway.
4. View the exposure information in the bottom area of the viewfinder or by looking at the rear display panel.
5. While the meter is activated, use your index finger to roll the Main dial left and right to change your shutter speed value until the exposure mark is lined up with the zero mark. The exposure information is displayed by a scale with marks that run from -2 to +2 stops. A «proper» exposure will line up with the arrow mark in the middle. As the indicator moves to the left, it is a sign that you will be underexposing (there is not enough light on the sensor to provide adequate exposure). Move the indicator to the right and you will be providing more exposure than the camera meter calls for. This is overexposure.
6. To set your exposure using the aperture, depress the shutter release button until the meter is activated. Then, using your thumb, hold in on the Av button on the back of the camera and then use your index finger to turn the Main dial right for a smaller aperture (large f-stop number) or left for a larger aperture (small f-stop number).

(I realized the lens for my camera is broken, and I will complete this LA when e new objective arrives).
