The higher the number of bit depth, the higher the number of possible colors available in the image. Bit depth or color depth is only one aspect of color representation, expressing how finely levels of color can be expressed (a.k.a. color precision). We know 1-bit color depth (2 1 = 2 colors) as monochrome, it is just pure black and white pixels. If we look at a grayscale 8-bit image, even though there are no other colors but black and white again, there are 2 8 = 256 possible shades of gray, in other words, 256 different intensity values of each of these colors, that can be used in the image.Īnd in the same fashion in a 10-bit grayscale image there are 2 10 = 1,024 possible shades of gray between black and white, and in a 24-bit grayscale image there are 2 24 = 16,777,216.īit depth represents the total number of colors a digital image can contain. Think of it as Color Depth.īit depth is the number of bits (0’s and 1’s) used to indicate the color of a single pixel. Images with higher bit depths can display greater range of colors, since there are many bit combinations available per pixel. This is not to say that the image will make use of all the colors in the palette, but they can be used to specify necessary colors with a certain level of precision. Bit Depth is a metric of how many unique colors are in the color palette of an image that are used to represent each of the colors.
