What is Bit Depth? How does bit depth and file size relate?
A bit is a binary digit, which can only have a value of 0 or 1. The colour of each pixel is stored in just 1 bit of space in the computer. Bit depth is the number of bits in each pixel. Color depth is the maximum number of colors in an image and is based on the bit depth of the image and of the displaying monitor. Color Resolution (color depth) is the number of bits of data used to store information about the color of each pixel in an image. This is also known as bit depth or color depth. The higher the color resolution, the greater range of possible colors in the image, and the larger the file size. Typical color resolutions are 8-bit, 16-bit, or 32-bit, although others are possible. Bit depth defines the number of colours available to each pixel within an image: Bit Depth Colours Available 1-bit black and white 2-bit 4 colours 4-bit 16 colours 8-bit 256 colours 8-bit greyscale 256 shades of grey 16-bit 32768 colours 24-bit 16.7 million colours 32-bit 16.7 million + 256 Levels of tran
