But I mentioned at the start of this article that 8-bit color images actually have 256 shades per primary color. In the above section, we saw that an 8-bit image can only hold 256 different shades of grey in total.

8-bit images allow up to 256 tones, whereas 1-bit images can have only two Bits vs Bits per channel The 8-bit image can hold 256 shades of grey whereas the image on the right can only hold either black or white.

A few areas of the 1-bit image might appear grey, but once enlarged to pixel peep, the difference becomes apparent as seen below. The right side of the image contains only black and white. The left side of the image is 8-bit whereas the right side is 1-bit. Take a look at the image below for a similar example. Since 2^1 = 2, there are only two values available here: 0 and 1 вЂ“ AKA black and white.ДЎ-bit image that only has pure black and pure white So, a 1-bit image can have only 2^1 values. As you may have gathered already, bit depth is merely 2 to the power of that number. To visualize bit depth more easily, let us take a simple example of a 1-bit image. In that example, the second rainbow would have a much smaller bit depth. But the first rainbow may be a gentle gradient with many thousands of individual colors if you zoom in on the pixels, whereas the second rainbow may be made up of just seven or eight colors and look much blockier. In other words, you could have two images of rainbows that both go from red to violet вЂ“ i.e., the same gamut. You can read more about color gamut at SpencerвЂ™s article on sRGB vs Adobe RGB vs ProPhoto RGB.Д«it depth, on the other hand, can be visualized as the distance between colors within the gamut. The range of colors which they can display is usually limited to a color gamut like sRGB or AdobeRGB, or a specific gamut based on the printer/ink/paper at hand. Electronic devices and printers are not able to display nearly as many colors as the human eye can see. Color gamut is a range of colors, usually used in the context of which range of colors a given device can display or printer can output. Some photographers confuse color depth with color gamut. For example, 8 bits can represent up to 256 shades (or, 2^8) of a given primary color. So, the definition of bit depth is the number of bits used by each color component to represent a pixel.

That is why any integer between 0-255 is considered вЂњ8 bitвЂќ it can be represented within eight binary digits. Now, when I try to convert the next decimal, 256, I would get 100000000, which is a 9 digit binary number. When I convert 255 into binary, I get 11111111, which is eight digits long. Let us consider the largest number that represents red, which is 255. Any non-primary colors are represented by a combination of the primary colors, such as вЂњ255, 100, 150вЂќ for a particular shade of pink. In digital photography, each primary color (red, green or blue) is represented by an integer between 0 and 255. For example, pure red is represented with the numbers вЂњ255, 0, 0.вЂќ Pure green is 0, 255, 0, and pure blue is 0, 0, 255. It is for this reason that bit depth is also known as color depth. One such combination is used per pixel, and millions of pixels make an image. Specifically, any color in digital imaging is represented by a combination of red, green, and blue shades. Most of us are aware of the fact that pixels are basic elements of any image.

Where does 16-bits/channel really matter?.
