What determines the lightness or darkness of an image? |
The exposure settings determine how much light reaches the light-sensitive image sensor. |
|
If the images that you are making with your digital camera appear too pixelated what setting must you adjust or check on your camera? |
. |
|
What effect would there be in the overall color balance if you used a tungsten light source with a daylight white balance setting? |
Amber |
|
Explain how underexposed and overexposed images differ from one that is normally exposed. |
- Underexposed: image that is too dark (light values) - Over-exposed: image that is too light (dark values) |
|
What are the two types of exposure meters and how do they differ in determining a correct exposure? |
- A reflected light meter provides an exposure reading that averages the amount of light that it receives; it will give the most accurate measurements indiffused light scenes. - An incident light meter measures the amount of light falling on a subject. |
|
What are two methods that can be used to override an exposure when using an automatic camera? |
exposure compensation setting |
|
What type of light will produce the best overall reading with digital cameras? |
. |
|
Explain what happens to the exposure of a scene when the majority of the values are dark. |
Over-exposed |
|
Explain a technique that could be used to render a correct exposure when photographing a backlit subject. |
Move close to the subject, take an exposure reading, recompose the image and expose the image with the close-up reading or use a +1 or+ 2 stop EV (exposure value) compensation adjustment. |
|
Define a high-contrast scene and explain what type of measures you would take to obtain a correct exposure when photographing in this type of situation. |
- A high contrast scene is one in which the range of tones exceeds the latitude of the sensor in a single exposure. - A method for obtaining an accurate reading in high-contrast scenes is to take a reading off a gray card in the same light and exposure normally. - You can also use the palm your hand for a substitution reading if you do not have a middle grey card. |

What piece of equipment would you need besides a camera to successfully produce images in HDR? |
