Digital Imaging Chapter 8 Workbook
Questions and Answers Graded A+
Why is sharpening applied to an image?
✔✔ To enhance edge definition and improve clarity.
What happens when an image is overly compressed?
✔✔ It loses quality and may show artifacts.
Why is optical zoom preferred over digital zoom?
✔✔ Optical zoom maintains image quality by adjusting the lens, while digital zoom crops and
enlarges the image.
How does HDR improve digital images?
✔✔ It balances light and dark areas, capturing more detail in high-contrast scenes.
What is the effect of using a slow shutter speed?
✔✔ It captures motion blur, creating artistic effects in moving subjects.

,Why do photographers use the rule of thirds?
✔✔ To create a balanced composition by positioning subjects along intersecting lines.
How does resolution affect image quality?
✔✔ Higher resolution provides more detail, while lower resolution reduces clarity.
Why do images sometimes appear distorted when printed?
✔✔ The resolution may not be high enough for the print size, causing pixelation.
What is the purpose of contrast adjustment?
✔✔ To enhance the difference between light and dark areas in an image.
How does a color profile affect an image?
✔✔ It ensures consistent colors across different devices and displays.
What happens when an image is underexposed?

, What is the purpose of digital imaging in modern technology?
✔✔ To capture, process, and display images electronically for various applications.
How does a pixel contribute to a digital image?
✔✔ A pixel is the smallest unit of a digital image, determining its resolution and detail.
What happens when an image is resized beyond its original resolution?
✔✔ It becomes pixelated, reducing clarity and sharpness.
Why is color depth important in digital imaging?
✔✔ It determines the number of colors an image can display, affecting image quality.
What is the advantage of using RAW image format?
✔✔ It retains maximum detail and allows greater flexibility in editing.
Why is white balance adjustment necessary in digital imaging?
✔✔ It corrects color temperature to ensure accurate color representation.
