Question: 1 / 465

When using your camera in JPEG mode, it processes the file using how many colors?

8 million

16.7 million

In JPEG mode, image files are processed using 16.7 million colors. This number arises from the use of a bit depth of 24 bits per pixel, where 8 bits are assigned to each of the three primary color channels: red, green, and blue (RGB). Each of these channels can represent 256 different values (from 0 to 255), which when multiplied together (256 red x 256 green x 256 blue) results in the capability to display approximately 16.7 million distinct colors.

This is a standard feature of the JPEG format, designed to maintain a balance between file size and quality, allowing for rich color representation while still compressing the image for easier storage and sharing. The other options suggest either fewer colors or more, which do not align with the established specifications of the JPEG format.
