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?

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?

• A. Pixel
• B. Bit Depth
• C. File Formats
• D. Image File Size

Answer: (B)

Color information for each picture element is defined by bit depth. Bit depth is how many bits are used to represent the color of each pixel, so it determines how many distinct colors can appear per pixel. For example, 8 bits per channel in an RGB image means 8 bits for red, 8 for green, and 8 for blue, totaling 24 bits per pixel and about 16.7 million possible colors. Higher bit depth allows more colors and smoother color transitions. A pixel is simply a location in the image where color data is stored, not the amount of color information itself. File formats describe how data is encoded and stored, sometimes supporting different color depths, but the number of colors per pixel comes from bit depth. Image file size varies with resolution, color depth, and compression, and does not alone indicate how many colors per pixel are available.
