2. Raster Graphics
• Give a definition of Raster Graphics
Raster graphics are made up of Bitmaps.
Bitmaps are graphics made from pixels. Each
pixel records the colour information of that
section on a image. They have a fixed
resolutions which means when enlarging the
photo it could lose definition.
3. Vector Graphics
• Give a definition of Vector Graphics
Vectors graphics are made up of vectors. They
are defined by a start and an end, points with
curves and points with angles. An example of a
vector is font. When you enlarge font it will
never get distorted round the edges. You have
small and big vectors and no loss in definition
will occur.
5. JPEG
Stands For JPEG
Used For/Example JPEG are used normally for photographs
and web format such as Facebook as they
save uploaded images as JPEGS.
Advantage An advantage of using a JPEG is being able
to save an image with a small file size this
allows you to send it and access it much
quicker and easier.Also uses less memory
so you can store more files.
Disadvantage An disadvantage of using a JPEG is the
photo losing quality due to
compression.Everytime an image is saved
after editing it keeps losing quality as less
pixels are saved each time.
6. TIFF
Stands For Tagged Image File Format
Used For/Example TIFFs are used for desktop
publishing.Documents in Adobe are often
saved as TIFFS.Also magazines use them.
Advantage An advantage of TIFFS is you can save
multiple pages in a single file.This is useful
for magazines companies to store lots of
there pages in one file and also saving it as
a TIFF allows you to edit it as many time
without losing image quality.
Disadvantage TIFFS will have be file sizes due to lots of
information being stored.This can make if
difficult to sent it to other people with
such big file sizes and also could take a
while to open it up.
7. GIF
Stands For Graphic Interchange Format
Used For/Example GIF are used for short digital animations
that are usually shown on the internet
such as Facebook.It creates a loop of
images that gives it the look of a video.
Advantage They have a small file size so makes it
easier to view and can send and also when
online can load fast but also keeps its good
quality.
Disadvantage The colour palette is limited so this can
make the GIF appearance bad with poor
quality. You cannot not go back a re-edit it
once you have saved it as a GIF this can be
a problem if you have missed something
out as you would have to start over.
8. BMP
Stands For Bitmap Image File
Used For/Example A BMP is similar to a JPEG and TIFF. They
save any pixel based images.
Advantage BMP saves images at a high quality as
when they are compressed they do not
lose any quality.
Disadvantage A disadvantage of pictures being saved at
a high quality is the file size will be large
and this can make it difficult to send or
open and also will take up lots of memory.
10. PSD
Stands For Photoshop Document
Used For/Example PSD files can be used for magazines front
covers and image manipulation.
Advantage An advantage of a PSD file is you can save
layers this allows you to come back and
edit images after saving. This is good if you
have missed something and be able to add
it in out without starting again.
Disadvantage An disadvantage of a PSD file is they can
only be opened in photoshop and has a
very large file size this can cause problems
when sending to other people as they can
not open it without photoshop and allows
takes up a lot of memory.
11. AI
Stands For Adobe Illustrator Art
Used For/Example AI is used to create graphics for company's
such as logos to represent something for
example clothing brand.
Advantage An advantage as an AI is you can make the
image small or large without losing any
quality this is really helpful when
promoting your brand in different ways,
for example you can make your logo very
big for a billboard and also make it small
for a leaflet with the same quality.
Disadvantage An AI file is limited when opening it as you
need specialist software this can cause
problem when sending it to people as they
might not be able to access it.
12. FLA
Stands For Flash File
Used For/Example A flash file is used to create games and
animations.Theycan include videos and
sound.
Advantage An advantage of FLA is the produce high
quality files but still have a small file
size.This is good if you wanted to upload it
online as it would not take long and
wouldn’t take long to open it either.
Disadvantage A disadvantage of a FLA is the software is
limited when accessing it. This means it
makes it more difficult to open it as it has
a specialist file.
13. WMF
Stands For Windows Metafile
Used For/Example A WMF are used for logos and graphic
companys.A WMF is similar to a AI file. A
window metafile is a windows format used
for clipart.
Advantage Just like an AI file images saved as a WMF
can be scaled small and large with no loss
in definition. It also can contain both
vectors and bitmap components.
Disadvantage A WMF can only be generated on windows
platforms as they are only available there.
15. Compression
Definition Lossy compression is the reduction in file
size by reducing the amount of
information which is saved.
Advantage An advantage of compression is it reduces
the file size so if wanting to upload a
image fast be compressing it will upload
it quicker as the quality is reduced.
Disadvantage A disadvantage of compressing an image is
you lose quality and makes the image
appear more pixelated, this is not good if
you wanted a high quality image online
you would have to not compress it and
just have to wait longer for it to upload.
16. Image Capture
Method Scanner
How is it used for image capture of
graphics
You are able to digitalise physical images
such as drawings. This is really good if you
are better at drawing as you can scan
them onto the computer and edit them.
Method Camera
How is it used for image capture of
graphics
A camera takes image by recording the
light with a sensor and the sensor records
information for all the pixels which
produces a image.
Method Graphics Tablet
How is it used for image capture of
graphics
A tablet is great for drawing digitally by
being able to use a mouse like a pen. This
allows you to control the drawing and
selection of the image.
17. Optimising
Why would you optimise? You would Optimise an image that is
uploaded on the web to check is it can be
easily viewed.
How can you optimise? You can do this by going into photoshop
an changing the file size. It is optimised by
reducing the file size, reducing the bit
depth, reducing the resolution and also by
compressing images.
Advantage to optimising An advantage of optimising you reduce the
file size so it make it faster to download
and open up on the internet.By having a
large file size it take longer to open up on
the web which makes people click off.A file
size should be no bigger then 500 pixels
wide.
Disadvantage to optimising A disadvantage of optimising is by
reducing the file size it reduces the
19. File Size
What could affect a Working Scale
(Photoshop) document file size?
Files on Photoshop a genuinely large
because of the layers and shapes. The file
size could also relate to the pixel
dimensions.
How could you reduce the file size of a
Working Scale document without
affecting quality?
You could reduce the files size by changing
the file type but keeping the working
scale. You can do this by changing the
bicubic automatic image to a bicubic
sharper o keep the image quality.
What is an advantage of scaling up images
before exporting?
An advantage of this is it allows you to
resize them without losing image quality
after exporting making it much easier to
resize.
What is a disadvantage of scaling up
images before exporting?
Scaling an image up will make the file size
much bigger making it much harder to
send or publish.
20. File Naming Conventions
What naming conventions could you use
when creating your video game assets?
I would name my file with a single file
name as leaving it as “untitled” or “new
document” is a bad idea as if lots of your
work are saved like this it would make it
hard to find a certain file. Also when
saving a file you have edited it is useful o
use number for example if you are editing
a magazine cover save it as magazine
cover (1) and so on.
Why is it a good idea to accurately name
your assets?
It is a good idea to name your assets
because if you don’t I will be really hard to
find certain documents within a folder if
they are all named similarly. So naming
your assets is key.
21. Asset Management
Why would you use folders when storing
your assets?
Folders help spilt up projects. If you are
working on several small project having
folder can help organize them up so it is
easy to access them as not having folders
it could make it more difficult to find a
certain project.
What folders would you create and what
would you save within them
I would create 1 main folder for the
course, for example “creative media” hen
create 4 new folders named the 4 project
we do. “photography”, “video games “,
“Print” and “Video”. And within these
folder place my files.
