2. Raster Graphics
• Give a definition of Raster Graphics
Raster graphics are made up of Bitmap, this is made
up of lots of little squares also knows as pixels, they
record colour information of a select part of an
image. In something such as a photograph when
you take photo, the image is made of raster
graphics and this is why when you zoom in enough
on an image you can usually see very small squares
with different colours in each.

3. Vector Graphics
• Give a definition of Vector Graphics
Vector graphics are made up of vectors aka
paths or strokes, unlike raster graphics, vector
graphic are defined by a start and end point not
lots of pixels.

4. Raster Graphics

5. JPEG
Stands For Joint Photo Expert Group
Used For/Example JPEG is the international format or images,
because of this it is used by photograph
and web designers. Most of the images on
the internet are in this format.
Advantage JPEG has a small file size so dose not take
up a lot of space on a hard drive and lodes
quickly on the internet. It is also
compatible to all devises e.g. mobile
phones, laptop and PC’s. They are also
good for small prints such as business
cards or photo booth pictures.
Disadvantage JPEG’s lose quality with multiple edits
due4 to compression and recompression
each time the image is edited.

6. TIFF
Stands For Tagged Image File Format
Used For/Example TIFF is the standard format for publishers
and magazine layout.
Advantage Adobe InDesign documents saved as TIFF
can be mulit-page documents. When
these files are resized and compressed no
quality is lost. It is a recognisable format
for most computers such as MAC’s and
PC’s.
Disadvantage File sizes are huge and will take up a lot of
space on a desktop compared to JPEG
files. TIFF files are far to large to be
compatible with the internet they will take
a long time to lode.

7. GIF
Stands For Graphic Interchange Format
Used For/Example GIF’s are used for short animations often
on the internet on websites such as
‘Tumblr’.
Advantage When there is no need to show a full video
GIF’s are used, they take up little space on
a hard drive. Also the loading time for
GIF’s is not long and they are compatible
for almost all devises such as PC’s, mobile
phone and laptop. GIF’s are used to pull in
a younger audience as they are short
simple animations.
Disadvantage Although they do not take long to lode the
quality is of a very low stander and can be
pixilated.

8. BMP
Stands For Bitmap Image File
Used For/Example BMP is mainly used for screen grabs icons
and other thing within windows.
Advantage Like TIFF files the quality is not lost when
the image is compressed and
recompressed. They are good for small
images such as icons. They are also
compatible to all versions of windows and
are widely supported by the web.
Disadvantage Unlike TIFF files the size of these images is
small taking up less room on a hard drive.
These files are not compatible to the
internet and

9. Vector Graphics

10. PSD
Stands For Photoshop Document
Used For/Example Front cover images, magazines.
Advantage PSD allow you to have multiple layers so
you can go back to the image and edit a
certain layer. Like TIFF and BMP files PSD
do not lose quality when compressed and
recompressed.
Disadvantage To access a PSD file you have to be within
Photoshop, this limits the people who can
access these images. Also the file sizes are
very large and take up lots of space.

11. AI
Stands For Adobe Illustration art
Used For/Example AI can be used to create company logos,
company graphics, technical diagrams and
digital cartoons.
Advantage AI have many workspaces which means
the images are of a better quality. It also
increases productivity because it includes
panel editing. Images do not lose quality
because it is made of vectors and can be
scaled big and small.
Disadvantage AI is not an easy piece of software and can
take some experience and training to get a
good grip of the format. As well as the
user enduing to be experienced the detail
in the images is key, this means the user
will have to be patient.

12. FLA
Stands For Flash File
Used For/Example Flash is used to create video games and
animations.
Advantage Flash creates high quality files and has
small file size meaning it dose not take up
lots of memory and can be stored on
things like USB drives. Also as well as
animations flash can include video and
sound.
Disadvantage Although they have small file sizes they are
not compatible to the internet and
therefore do not run on the web, this
means that the files have less usage.

13. WMF
Stands For Windows Metafile
Used For/Example Used by company's and business company
logos and clip art in windows.
Advantage WMF dose not lose definition when it is
scales bigger or smaller. They can also
contain both vectors and bitmap
components this gives them more
flexibility. Files can be saved in to a JPEG
form and placed straight into a Microsoft
Word document. As well as this old
programs and software will support MWF
files.
Disadvantage PowerPoint sometimes dose not support
this file format and tends to glitch, this is
very likely with some types of graphs.

14. File Format Capture
and Optimising

15. Compression
Definition Lossy Compression is the way in which file
sized are reduced by reducing the amount
of information that is stored within them.
Advantage The files sized become smaller meaning
they are easy to store and take up less
space on a hard drive or memory stick. It
also gives the ability for an image such as a
logo to be put in both a logo and a bill
bored without losing quality. This can
depend on which type of file format you
chose to use.
Disadvantage Some files that are created as raster
graphics can lose quality when
compressed. This can cause the image to
become pixelated and can look
unprofessional.

16. Image Capture
Method Scanner
How is it used for image capture of
graphics
A scanner is designed to copy sketches and
drawings and put them on to the
computer so they can be edited.
Method Camera
How is it used for image capture of
graphics
Cameras are easy to use and are mostly
high quality, clicking the button and the
picture is saved.
Method Graphics Tablet
How is it used for image capture of
graphics
Graphic Tablets are tricky to use but can
be very effective, they have a stylist which
can be controlled with flexibility. They can
be used for images and handwriting.

17. Optimising
Why would you optimise? Optimising ensures and easy web viewing,
it also decreases file sizes meaning they
are easier and quicker and downloading
and loading on the internet.
How can you optimise? We can use optimising to ensure that the
images which we put on the internet load
easily and can be views quickly as people
looking at websites do not like to wait for
things to load.
Advantage to optimising Images have a smaller file size and load
quicker on the internet.
Disadvantage to optimising When an image is optimised the quality is
lost and the image can become pixilated.

18. Storage

19. File Size
What could affect a Working Scale
(Photoshop) document file size?
The amount of layers or the size of an
image can effect the document file size. To
reduce the file size images can be
converted to JPEG.
How could you reduce the file size of a
Working Scale document without
affecting quality?
To make a file size smaller without losing
quality the image would have to be made
in vector graphic instead of raster graphics.
What is an advantage of scaling up images
before exporting?
The advantage of this is more detail can be
seen within the image.
What is a disadvantage of scaling up
images before exporting?
The file size increases when the image is
scaled up.

20. File Naming Conventions
What naming conventions could you use
when creating your children's books
assets?
• I will have a file for the pages and a file
for the extra work on Photoshop so my
work dose not get confusing
• In Photoshop I will name the layers so I
know what layer is what instead of
having loads layers names ‘layer’.
Why is it a good idea to accurately name
your assets?
It is a good idea to accurately name your
files on Photoshop as well as in your
documents so that you do not lose your
work by saving it in a place you will not be
able to find again. Also it makes it easier to
navigate you way around your files and
layers.

21. Asset Management
Why would you use folders when storing
your assets?
Using folders to store assets makes it
easy and quick to find what you are
looking for, like in Photoshop you could
have 50 layers with no name and you
wouldn’t know which was which.
What folders would you create and what
would you save within them
I would create a folder for each page of
my children's book and a folder for
each character.
