CPP Exposure Control

Question 1

In Certified Professional Photographer, what is the "exposure triangle" in photography?

Accepted Answer

The relationship between aperture, shutter speed, and ISO

Answer

The exposure triangle describes the three variables that control the amount of light reaching the camera sensor: aperture (lens opening), shutter speed (exposure duration), and ISO (sensor sensitivity).

Question 2

What does aperture control in Certified Professional Photographer?

Accepted Answer

The size of the lens opening, affecting depth of field and light intake

Answer

Aperture controls the size of the lens opening (measured in f-stops). A wider aperture (lower f-number) allows more light and creates shallower depth of field; a narrower aperture increases depth of field.

Question 3

In Certified Professional Photographer, what is "depth of field"?

Accepted Answer

The zone of acceptable sharpness in front of and behind the focused subject

Answer

Depth of field is the range of distance in a photograph that appears acceptably sharp. It is controlled primarily by aperture, focal length, and subject distance.

Question 4

What is white balance used for in Certified Professional Photographer?

Accepted Answer

To ensure accurate color reproduction by compensating for the color of the light source

Answer

White balance adjusts the camera's color processing to compensate for the color temperature of different light sources (daylight, tungsten, fluorescent), ensuring whites appear truly white and colors are accurate.

Question 5

In Certified Professional Photographer, what is the difference between RAW and JPEG file formats?

Accepted Answer

RAW preserves all sensor data for maximum editing flexibility; JPEG is compressed with some data loss

Answer

RAW files contain all data captured by the sensor, providing maximum flexibility for post-processing. JPEG files are processed and compressed by the camera, resulting in smaller files but with some data loss.
