Photography and Media Camera Equipment & Technology 1 — Questions and Answers
Question 1: What does 'ISO' stand for in photography?
- International Standards Organization (Correct answer)
- Image Sensor Output
- Internal Signal Optimizer
- Integrated Shutter Operation
Correct answer: International Standards Organization
ISO stands for International Standards Organization, and in photography it measures the camera sensor's sensitivity to light.
Question 2: Which lens type provides a field of view closest to human vision, typically around 50mm on a full-frame camera?
- Wide-angle lens
- Telephoto lens
- Normal lens (Correct answer)
- Fisheye lens
Correct answer: Normal lens
A normal (or standard) lens, around 50mm on a full-frame sensor, most closely replicates the natural perspective of human vision.
Question 3: What is the function of a camera's aperture?
- Controls shutter speed
- Controls the amount of light entering the lens (Correct answer)
- Adjusts white balance
- Sets the ISO value
Correct answer: Controls the amount of light entering the lens
The aperture is the opening in the lens that controls how much light reaches the camera sensor by adjusting its diameter.
Question 4: What does 'full-frame' refer to in digital camera terminology?
- A camera with a built-in flash
- A sensor the same size as 35mm film (36x24mm) (Correct answer)
- A camera with a 4K video mode
- A memory card with maximum capacity
Correct answer: A sensor the same size as 35mm film (36x24mm)
Full-frame refers to a digital sensor that matches the dimensions of traditional 35mm film at 36x24mm.
Question 5: Which camera metering mode measures light only from the center of the frame?
- Matrix/Evaluative metering
- Spot metering
- Center-weighted metering (Correct answer)
- Highlight-weighted metering
Correct answer: Center-weighted metering
Center-weighted metering averages the light reading across the frame but places the most emphasis on the central area.
Question 6: What is the crop factor of a typical APS-C sensor compared to full-frame?
- 1.0x
- 1.5x or 1.6x (Correct answer)
- 2.0x
- 3.0x
Correct answer: 1.5x or 1.6x
Most APS-C sensors have a crop factor of approximately 1.5x (Nikon/Sony) or 1.6x (Canon) compared to a full-frame sensor.
