Bit depth refers to the amount of information your images carry. A standard JPEG image is an 8-bit image. An 8-bit image has exactly 256 levels of colors and tones which can be manipulated (or played with) in any photo editing software (including Photoshop).

 

A 16-bit image has 65,536 levels of colors and tones. Now, that’s a significant jump from an 8-bit image. So, with a 16-bit image, even if we happen to lose about half the colors and tones, we still end up with 32,268 levels. That’s still an impressive number.
