Learning Activity – Exposure Basics

Question 1

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 cameraImage

2. Name all the functions / buttons on the back of your cameraImage

3. Explain how you would set the correct ISO
Changing the ISO setting on the camera will change the sensitivity to light. So a low ISO is less sensitive to light than a high ISO is. If one is to take pictures with a lot of light, you could usually use a low ISO because then you have enough light to do so. But shooting in a place with little light, it would be smart to use a higher ISO if you dont have a tripod. One negative thing with a high ISO is that the image gets more “grain” or “noise”, making the image quality worse.

4. Explain how you would change the aperture
The aperture is what decides how much light is allowed through the lens. A high aperture (ex. f22) would let very little light through the lens, making it ideal for long exposure shots. Also a benefit of using a high aperture, you would get a sharper image with less depth of field than you would with a low aperture. Therefore high apertures are good for landscape pictures, or pictures that you want sharp. Low apertures let a lot of light through the lens, making it good when taking pictures of something fast where you need a lot of light as fast as possible. A low aperture will also make the depth of field much bigger and can be really good for abstract photography.

5. Explain how you would change the shutter speed
The shutter speed is what desides how fast the shutter will open and close. Meaning it desides how much light you want to hit the image sensor. A long shutter speed would let a lot of light through to the censor, making is ideal for using in low light areas with a tripod. A lot of different effects can be created by using a low shutter speed, abstract photography use this a lot. Short shutter speeds are used for freezing time, for example taking pictures of a sports athlete or splash in the water. Shutter speed can also be refered to as exposure time.

5. 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:
