Homework Help: Questions and Answers: What is the phenomenon called when a camera itself accurately controls the exposure in the image?
A. aperture priority mode
B. shutter priority mode
C. automatic shutter bracketing
D. automatic exposure bracketing
E. aperture secondary mode
Answer:
First, lets understand Exposure:
Exposure refers to the amount of light that reaches the camera sensor, which determines the brightness of an image. It is controlled by three main factors: aperture (how wide the lens opens), shutter speed (how long the sensor is exposed to light), and ISO (sensor sensitivity).
Given Options: Step by Step Answering
a) Aperture Priority Mode
- In this mode, the photographer sets the aperture, and the camera automatically adjusts the shutter speed to properly expose the image. This is not a full automatic exposure control; it’s more focused on depth of field.
b) Shutter Priority Mode
- The photographer sets the shutter speed, and the camera adjusts the aperture to maintain the correct exposure. Again, this is not full automatic exposure control.
c) Automatic Shutter Bracketing
- This mode involves taking multiple shots at different shutter speeds to ensure one of them has the correct exposure, but it’s not an automatic exposure mode.
d) Automatic Exposure Bracketing
- This is a process where the camera automatically takes multiple shots at different exposure levels (for example, one underexposed, one correctly exposed, and one overexposed). The camera takes control of the exposure settings to ensure accurate results.
e) Aperture Secondary Mode
- This mode doesn’t exist as a standard option in photography, so it can be eliminated.
Final Answer:
Based on the analysis, the correct answer is:
d) Automatic Exposure Bracketing
The phenomenon where the camera automatically controls exposure by adjusting settings for proper image brightness is Automatic Exposure Bracketing (D).
