Learning Activity – Exposure Basics – Week 8

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

  1. Name all the functions / buttons on the front of your camera
  2. canon frontName all the functions / buttons on the back of your camera

canon back3. Explain how you would set the correct ISO

I would press the ISO button and use the main dial to choose the right level.
The lower ISO the better quality of the picture I will get. For a sunny day I might choose low ISO e.g 100, for night shoot I might screw it up to 1600.

4. Explain how you would change the aperture

In manual modus, I would change it by turning Quick Control Dial. In aperture priority mode I would turn the Main Dial.

5. Explain how you would change the shutter speed

In both, Shutter Priority mode and Manual mode I would use the Main Dial. It is important to know that if you change the shutter speed in manual mode, you have to also change the aperture or ISO to maintain the right exposure – if you are in the same light environment.

Selecting the proper white balance

Take your camera outside into a daylight environment and then photograph the same scene using different white balance settings. Pay close attention to how each setting affects the over- all color cast of your images. Next, try moving inside and repeat the exercise while shooting in a tungsten lighting environment. Finally, find a fluorescent light source and repeat one more time.

Take five pictures every day for the next five days. The subjects of your pictures can include a series of different objects, people and landscapes. Apply the manual settings as explained in your textbook. Submit your six best pictures at the end of the week, listing the following with each picture:

  • ISO
  • Aperture
  • Shutter speed

I used my Canon 40D with Canon EF 40mm f/2.8 STM Lens and took pictures of my Savannah called Devon.

ISO 1600 * F 3,2 * Shutter Speed 1/15 sec
ISO 100 * F 2,8 * Shutter Speed 1/100 sec
ISO 1250 * F 2,8 * Shutter Speed 1/200 sec
ISO 400 * F 4,0 * Shutter Speed 1/200 sec
ISO 400 * F 3,2 * Shutter Speed 1/200 sec
ISO 200 * F 4,5 * Shutter Speed 1/80 sec
