Bit depth

Bit depth refers to the color information stored in an image. The higher the bit depth of an image, the more colors it can store. The simplest image, a 1 bit image, can only show two colors, black and white. That is because the 1 bit can only store one of two values, 0 (white) and 1 (black).

What is bit depth 32?

“32 bit” also usually means 32 bits total per pixel, and 8 bits per channel, with an additional 8 bit alpha channel that's used for transparency. 16,777,216 colours again. This is sometimes referred to as 32 bit RGBA.

What is the bit depth of an image?

Bit depth refers to the number of colours that can be displayed by a digital device. The higher the bit depth, the more colours used in the image and, consequently, the larger the file size. JPEG images are always recorded with 8-bit depth. This means the files can record 256 (28) levels of red, green and blue.

What is 8 bit depth?

The number, 256, is 2 raised to the 8th power or the 8-bit color depth. This means that each of the RGB channels has 256 shades so there are 256x256x256 or 16,777,216 colors in total in this 8-bit RGB system. An 8-bit color system is capable of producing over 16 million colors.

What should your bit depth be?

What Bit Depth Should I Use? For consumer/end-user applications, a bit depth of 16 bits is perfectly fine. For professional use (recording, mixing, mastering or professional video editing) a bit depth of 24 bits is better. This ensures a good dynamic range and better precision when editing.
