Bit depth is a fundamental concept in digital imaging that refers to the number of bits used to represent color information for a single pixel in an image. In other words, it determines the amount of information that can be stored for each pixel in an image. The higher the bit depth, the more shades of color can be represented, leading to a more accurate and detailed image. Bit depth is closely related to color depth, which refers to the number of colors that can be displayed or printed. However, color depth is not always the same as bit depth, as some color spaces may use more bits to represent certain colors than others. One important application of bit depth is in digital cameras, where it determines the range of colors that can be captured in an image. Higher-end cameras often have the ability to capture images with higher bit depths, resulting in more accurate and detailed color representation. Another important aspect of bit depth is its impact on file size. Images with higher bit depths require more storage space, which can be a limiting factor in some applications. For example, images used for web design or online publishing are often compressed to reduce file size, which can result in a loss of color information. In summary, bit depth is a crucial concept in digital imaging that determines the amount of color information that can be stored for each pixel in an image. It has important implications for image quality, color accuracy, and file size.

Bit depth is a term used to describe the number of bits used to represent color information for a single pixel in an image. Specifically for computer graphics, it is an indication of how many shades of color can be used to represent the image. For example, an 8-bit image can only have 2^8 or 256 shades of color whereas with a 10-bit image 2^10 or 1024 shades of color can be represented. Bit depth is an important concept in digital imaging because it ensures the highest quality color representation for an image. One of the most important works done on bit depth comes from the paper by Kender and Belousov, titled “Theory of Color Imaging Systems” (2012).
