Just a bit of Depth

First of all … ‘Bit’ is the smallest unit of data. 8 bits comprise a byte. 8 bit images get used in the digital world in things such as inkjet printers and usually the screen you’re looking at right now (monitor). Therefore things are used to create images that you usually see are 8bits. Bit Depth is showing you the number of bits which get used to represent the smallest unit of information so this could be a pixel or a byte in things such as a graphic date file or in an audio or video. If the bit is a greater bit depth than the quality will be a lot better when storing or reproducing an image or sound. 1 bit would be a black and white image and there it only black and white colours in it. 8 bit would be a grey scale image storing 256 colours and finally a standard image which 24 bit would be RGB so 16.7 million various colours.

TIP! - Monochrome is not the same as grey scale however it does mean one colour. An image known as a monochrome image does only have one colour but these colours could be different shades. If you were to look at a monochrome monitor they only use one colour in the background and another colour to display text or possibly an image. It can be referred to as a two tones image instead of an image with several or more shades of a single colour. Most computers used to be monochrome displayed. They would have green text and a black background however colours such as red and orange would be used as text. Colour monitors started around 1980’s and monochromes still gets displayed and are still used for several years as computer terminals.

BPP or Bits per Pixel is showing the number of bits which is has information stored per pixel of an image or of something which is displayed by a graphic adapter. When looking at colours, the more bits that are in the colour the more colours can be represented. However this would mean that more memory would be required to store of display your image! If you were to allow 8 bits so 1 byte per component so 24 bits per pixels that would give you 256 levels for each component and that would be over 16 million different colours. The human eye can’t actually distinguish this many colours!

High colour vs True colour

High colour graphics is one method of storing images information in a computer’s memory. Each pixel represents two bytes! The colour is represented by all 16 bits however some of the devices also support 15 bit high colour. Microsoft have been using high colour to distinguish their display systems which use more than 8 bits per colours from their traditional 8 bits per colour channel formats. Computers can use a number of different systems to display colour which includes RGB and (red, green blue) and CMYK (Cyan, magenta, yellow, and black).When you look at a digital photograph on your computer screen, even though it looks like a normal photo and you can clearly make out the people and/or objects in the photo, what you’re really seeing is nothing more than a massive collection of colored squares, squares that are normally too small for your eyes to see them individually, yet when placed side-by-side and above and below each other, they form a complete image, which is the photograph you’re looking at on your screen.

It’s an appropriate name, since pixels are in fact the elements which make up our digital pictures. Pixels are the building blocks of any digital photo or image, sort of like how those fancy Lego toys they sell at your local Toys R Us are really nothing more than a collection of small, individual Lego pieces, or how pieces of a jigsaw puzzle come together to form a complete picture, yet if you’re standing close enough to the puzzle, you can still see the individual pieces. Pixels make up your digital photos and images in much the same way.The

24 bit colour has 16.7 million colours and this is called ‘true colours’ which is a reference to the accuracy of shading and hue available. Black and white are common colours to use however computer did use to be operated with black and green colours. Makers were than able to add another bit to create the possibility of about four more colours. In time bits were added and more and more colours became possible through 8 bit, 16bit and 24bit colour.
