VECTOR IMAGES
A vector image is an image which is made up of line art. This basically means that the image is made up off anchor points such as fill,stroke,curves, lines and shapes. For example the picture which is aligned on the right is a vector image of Marilyn Monroe. you can tell that most of the image is basically lines and which has been filled to create shadow and depth within the image to help create a shape.
The advantages of using a vector image is that it can be any size because no matter how much you zoom in the lines and shapes will still be clear. However in a raster image if you zoom in you will be able to see the pixels of the image but in a vector image no matter how much you zoom in the line will still be smooth as you can see in the picture aligned to the left. In the picture there are two bottles but they are both created differently. The one on the left is an image made in vector while the one on the right is created in raster .You can tell when zoomed in the vector image hasn't changed while the bit map image looked more blurred and 'blocky'. This is because raster is made out of pixels.
I've previously created an image by using lines and the fill,stroke etc. For example I first decided to use the pen tool in illustrator to create lines for my image and then edited the line stroke till it was up to the thickness i preferred. I then filled in the colour until all my image was filled in.Even when I zoomed into my characters face the image doesn't look likes its built up off pixels and is still clear, as you can see in the image to the right. Vector image is amazing if you want to create big image but don't want any pixels within the image. Vector images can be saved into several formats such as WMF, SVG etc.

RASTER IMAGES
An raster image is a digital image for example when you take a picture on your phone. A raster image is an image which is built up of pixels for example in picture aligned to the right if you zoom in to the picture you can see all the pixels.
A raster image is also known at a bit map and can be saved in JPG, Gif, tiff and BMP formats.
To the left is an example of a raster image that i created in photo shop I did this by using different layers to create an realistic photo. However if I zoom in you can easily see all the pixels in the picture.

THE PIXEL Pixels is the smallest element in a picture which can come in variety of shapes and sizes although they are all made up off primary/rgb colours. If you zoom into a bitmap you will see small boxes all ranging in different colours for example in the image to the right is a landscape of the sea. If you zoom into the see you will be able to all the pixels and easily tell that each block are not the same colour. This is basically because the computer doesn't see an image as an image and sees it all as blocks so it will automatically colour in the blocks which result in being the picture. The smaller the pixel the better quality the overall picture will be.

COLOUR DEPTH
Colour depth is also known as bit depth. This is basically means how many different shades of colours you can use. For example an image with a 1 bit colour will only be able to use 2 colours while a 8 bit colour will be able to use 256 colours.
Colour depth is made by multiplying the bit colour by two for instance;
1 bit colour is 2 x 1 which equals 2. This means that the bit rate will have 2 colours which is normally black and white.
4 bit colour (2 x 4) = a 16 colour pallet this can still be more of a block.
8 bit colour (2 x 8)= a 256 colour pallet this is usually the bit colour a giff uses.
24 bit colour (2 x 24) is the most modern pallet which make it look like its been photographed and not a block like the 4 bit colour. 24 bit colour is more expected be used in more modern games and films because of how realistic the quality is. The higher the bit the higher the colour depth is.

COLOUR MODELS
A colour model is a easy way to define what a colour is for example the model will describe how the colour will appear on the screen or when you print something off. There are three different types off colour models to help describe the colour.
RGB- Rgb is one of the most popular colour model because its more screen based and has up to 256 addictive colours for example rgb has 256 shades of red, blue and green. However RGB colours look more dull on paper when printed than it does on the computer.
RGB is useful for designing websites because rgb colours can be shown in a code which makes it easy to put colour in blogs etc.
I used the rgb model when i was using the software illustrator and Photo shop. In the picture to the right is a print screen of my work in photo shop. I've opened up the colour picker which allows me to pick my colour. To the right of the colour bar you can see the rgb numbers for example in the colour I've picked its got 51 Red, 102 green and 102 blue. The code for this colour is below the numbers and is next to a hash tag for example the code is '#336666'. You are then able to copy the code and use the exact same colour in a website etc. However if any of the red,green or blue numbers are increased or decreased then it will result in a complete different colour and code.
CMYK- is more popular for printing because cmyk is based around subtractive colours such as cyan, magenta, yellow and black. These four colours are normally used by modern printers and print off full colour on paper. This works amazingly well for magazines and art work because CMYK model gives off a good quality of colours.
You can see in the example in the rgb section it also has the colours cmyk.
Lab- The lab model is the last colour model which helps describe the colour however this model is much more complex than the CMYK and the RGB colour this is because the L in lab controls the lightness and darkness of the colour for instance in the example above next to the code you can see there is lab percentages. For that particular colour the Lightness is at '40%' but if i decreased the percentage to a lower number such as 20% the colour will be more dark.
The A and B basically change the colours for instance B makes the colour turn into more of a green and pink tone while the blue makes it more of a blue and yellow tone of colours.

RESOLUTION
The resolution is basically the number of pixels on a screen. The resolutions is how sharp and clear the picture will be but it all depends on resolution and the size of your screen for example if their is a a small picture with a million pixels the pixels will be made to fit in a small picture so if the image is then put into a larger image the pixels will be stretched and the resolution wont have as much quality.
As you can see in the picture to the right there is several images of a dog. However each image has a different amount of pixels, it is easy to see that the more pixels the better resolutions the picture is.

ANTI-ALIASING
Anti-aliasing makes jagged lines look more smooth and straight. You can tell if something has used anti aliasing when you zoom into a picture and can see a jagged line, This means that the graphics overall wont be smooth. Anti-aliasing is done by putting different shades of Gray pixels around the black line to make it blend into the background more, this creates a effect of the image/bitmap looking like its more faded in because the lines will look a lot more smoother. In the image aligned to the right there is two 'A's the first A hasn't used anti-aliasing while the 'A' on the right has. You can clearly see the Gray pixels around the black line helps fade the 'A's line making it look less jagged.

ASPECT RATIOThe aspect ratio is the width and height of a screen this creates the shape of the screen. This helps knowing what size a image or a video needs to be. For example if the aspect ratio is 2.35:1 the width of the screen is 2.35 while the height is 1 for instance a classic TV has a aspect ratio off 4:3.
To the right is some examples on how the aspect ratio determines the size of a screen.

FILE FORMATS -
bmp, png, gif, tiff, jpg, psd, pdf, eps and ai
A file format is basically a different format which you can save your data in, different formats are used for different things. For example giff and JPG are all formats for images which can be found on a web page etc while Html format is used for the wording/text on a web page. The PDF is a optional file format while using some adobe programs such as Photo shop while a word document will be saved as a '.doc' format. The most popular formats are Html,Jpeg and Mp3. MP3 is a format is used for media files such as music.
Each format can be used in their own particular way for example you cant put a html file format in a program which doesn't support that file for example power point. Because the programme would not be able to read the format. The name of a file is usually saved with the ending of the file format which was used for example if you save an image off the moon by using the Internet. The image will be saved as "Moon.JPG." While a word document will be saved as "NAME.Doc"

COMPRESSION
Compression is used to make a file smaller and to edit colours which are more suitable. Compression can be used by the most popular formats such as Jpeg, Gif and PNG. All formats have a different effect on the compression for example Jpeg is used to format digital photos as well as using lossy. Lossy helps gets rid of different colour variations which are to subtle to the human eye. While the format PNG uses losseless as a compression which uses pixels to guess the colour on nearby pixels. As you can see on the example image the colour differences aren't too extreme but is still noticeable when compared to the original image.

IMAGE CAPTURE DEVICES
A image capture device is basically a process of taking a digital image. For example to take a digital image you need a device with a vision sensor e.g camera, smart phone, tablet, laptop etc. There is a lot of devices which are able to take a picture which basically has a hardware interface which allows you to do a frame grabber which captures the image/Video.

OPTIMISING
Optimising an image is important because it allows the image to have the right balance between file size and the picture quality. Optimising an image is important if you are putting the image on a website because images take more time to load than writing etc on the web page. Optimising the image speeds up the loading because optimising makes the image files smaller. However optimising an image can result in loosing bit depth, resolution and dimension. To stop this it is important to compress the size by using the right file format for example giff file is used mostly for images made up of drawings and shapes so the image wont be to detailed.

STORAGE AND ASSET MANAGEMENT
Asset management is also known as 'Dam. Dam is short for digital and asset management. Dam is used to make storage etc a lot more organised in technology to improve the performance of their data storage resources. This includes dam having to do a virtualization, replication, mirroring, security, compression to help manage the data. An advantage of this is that it allows computers to hold more data easier than organisations creating computers with a bigger hard drive because it is a lot more cheaper to use dam than to create a new computer every time there isn't any room for data.
