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.

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.

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.

Unit 30 M1
Monitor: A
Monitor has limitations such as the resolution of the monitor because if you
use an old monitor you can’t be 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.
Digital camera: When 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.
Scanner: The limitations of a
scanner are that the scanning screen itself may not be big enough to cover what
you want to scan. For example if you have an 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.
Printer: The limitations of a
printer include the replacing of the ink. Ink can be very expensive comparing
to what printer you have. The better the printer is 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.
Illustrator: 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.
