Bit Depth

Bit depth refers to the amount of information used to represent each pixel in an image or each sample in audio. In digital images, higher bit depth means more colors can be represented. For example, an 8-bit image can display 256 colors, while a 16-bit image can show over 65,000 colors, leading to smoother gradients and more detail. In audio, greater bit depth allows for a wider dynamic range and better sound quality, as it captures softer and louder sounds more accurately. Essentially, higher bit depth enhances the richness and precision of digital media.
