Pixels into Binary

Binary in a image

The image bellow shows you what a binary picture is. so 10 could be the colour red. and 01 could be white. The image in the middle shows one coloured in.A letter 'a' magnified 16 times using pixel doubling

Information on Bits in photos

8bit

A common sample format is 8bit integers, 8bit integers can only represent 256 discrete values (2^8 = 256), thus brightness levels are quantized into these levels.


12bit

For high dynamic range images (images with detail both in shadows and highlights) 8bits 256 discrete values does not provide enough precision to store an accurate image. Some digital cameras operate with more than 8bit samples internally, higher end cameras (mostly SLRs) also provide RAW images that often are 12bit (2^12bit = 4096).


16bit

The PNG and TIF image formats supports 16bit samples, many image processing and manipulation programs perform their operations in 16bit when working on 8bit images to avoid quality loss in processing.
