A Monitor has limitations such as the resolution of the monitor because if you use an old monitor you cannot be completely accurate with the pixels. Meaning the piece you’ve made on Photoshop for example does not look the same overall printed out because the monitor could not keep up with the software. However to resolve this you could buy a calibrated printer meaning the colour schemes are linked. Therefor the overall piece looks the same on the paper as it did on the monitor.

Using a digital camera the pixels can be blurred when enlarged. This is because the picture taken is small and enlarging it stretches out the original photo. A SD Card is used to store memory of your pictures. The mega pixels of a camera determines the amount of pictures you can take. For example a 1GB will only allow you around 20 pictures.

A scanners limitations are that the scanning screen itself may not be big enough to cover what you want to scan. For example if you have a A4 scanner then you can only scan A4. Unless you scan A3 you have to scan both sides and join the 2 pieces together on Photoshop. More limitations are that the scanner must be cleaned frequently unless you end up with finger prints and scratches on the scanning screen. These marks will show up on the monitor when you scan something it will make the piece blurred where the marks are.

A printers limitations include the replacing of the ink. Ink can be very expensive comparing to what printer you have. The better the printer the more expensive the ink. The ink must be replaced to be able to print. The print size is also a limitation. If your printer can only print to A4 you cannot print off A3. But you can by printers which printer a variety of print sizes.

Photoshop is very time consuming it takes ages to learn how to use all the tools on the software and put them into action. You have to know how big to make an image resolution. The price is also a limitation as it is very expensive it is over £400. Not many people would not pay for that software.

Illustrator is very expensive. It is a vector so you can always change the size of the image. However it is very time consuming and will take a long time to get a hand of the software as it is very confusing. Another disadvantage is that it is very expensive software to have. Although it is worth the money.

	Graphic type	Describe how the graphic is constructed and why you chose the graphic type	How will the final file be saved?
Internet graphic	Bitmap	When a photo is taken on a Digital camera or when an image is scanned from a magazine a bitmap graphic is created. A bitmap is made out of tiny parts these are called pixels, they usually come in all different colours. You can edit a bitmap and also edit every individual pixel. This is because a computer has stored information about every pixel in the image. A bitmap graphic is usually quite large. However when you change the size of a bitmap graphic the image becomes distorted meaning the graphic loses quality.	Jpeg, Gif or Png
Van sign graphic	Vector	A Vector graphic is created in graphic packages. But unlike bitmap they consist of shapes called objects. You can edit each object individually by shape size and colour. Even though a vector can be quite large it does not need much memory to be stored. Therefore the file size of a vector is usually small. They are also scalable meaning when you change the size of them they do not lose quality.	EPS, AL, PDF, SVG or DXF
Brochure	Writing-Vector Pictures-Bitmap	You would use both vector and bitmap. Bitmap for pictures because you would want them to look more lifelike. Whereas a vector would be better for writing because it will stay clear making it easier to read.	PDF
