312-49 Question #150: Real Exam Question with Answer & Explanation
The correct answer is B: Bit Depth. Bit depth (also called color depth) defines the number of bits used to represent the color of a single pixel, which directly determines how many unique colors are available. For example, 8-bit depth allows 256 colors, 24-bit (true color) allows ~16.7 million colors. A pixel is si
Question
An image is an artifact that reproduces the likeness of some subject. These are produced by optical devices (i.e. cameras, mirrors, lenses, telescopes, and microscopes). Which property of the image shows you the number of colors available for each pixel in an image?
Options
- APixel
- BBit Depth
- CFile Formats
- DImage File Size
Explanation
Bit depth (also called color depth) defines the number of bits used to represent the color of a single pixel, which directly determines how many unique colors are available. For example, 8-bit depth allows 256 colors, 24-bit (true color) allows ~16.7 million colors. A pixel is simply the smallest unit of an image; file formats define how image data is stored and compressed; image file size is the total disk space the image occupies — none of these specifically describe the number of available colors per pixel.
