1. Vector
Vector graphics make an The lines and curves

looking blurry or pixelated
unlike a bitmap image which
can only be stretched so
much.
Usually bitmap images are
more photographic images
and then vector are shapes
and lines and text. That’s why
when you make text a big size
on word or some software it
doesn’t blur it looks exactly the
same just bigger.

2. Resolution are lots of tiny
squares of colour and the
higher the resolution the
better the little squares all add
up and blend together to
create a picture that looks
clear sharp. Where as if the
resolution is low the squares of
colour will be more

3. Aspect Ratio is the width and
the height of an image. One of
the most popular resolutions is
widescreen because of the
TV’s and how big they have
now become, its also
becoming more common on
newer laptops. Lots of touch
screen phones can be turned
to the side and the screen will
turn to match the way the
phone is being held and the
aspect ratio stays the same. The screen sizes are all different but the first and last

breaking the aspect ratio. doesn't looked stretched.
The screen orientation is changed
when the phone is turned to the
side but it stays the same and still
fits to the screen. The aspect ratio
adjusts to the move.

4. This is an example of an animated GIF. This
picture moves as you can see the two screen
shots of the image show that he moves by
taking his hat off then putting it back on. Gifs
allow an image to move whether it’s a real
picture or animation like this one.
A JPEG is a format that you can change
files from word or excel or other things into
to make it a picture. When you scan a
picture to a computer you can choose an
open to save it as a jpeg so you can send
a picture to someone so they can read it
exactly how you see it because its just a
picture of it. This is an example of someone
saving a file as a JPEG so it will be saved as
an image.
People use the option Tiff file to save their work if they
are saving something big or of high quality because a
Tiff file is specifically for very large and high quality
images. People who are scanning and faxing things
usually use Tiff to save it. This is an example of a fax
someone has been faxed and opened as a tiff file.
There is a lot of information so it might be a big file so
this is why this format has been used.

5. An EPS file is one of the most versatile file
formats and can be used to save
text, graphics and images. A file like this
would need to be saved as an EPS file. It is a
Photoshop file and has many layers of
graphics and has the original image file
underneath.
PSD files are Photoshop files. All work that you
save on Photoshop is saved as a PSD unless you
change it to another file format. This is because it
saves the file as it is in photo shop with all the
layers, text, clipping paths and anything you
might have done on the document. This is so that
it can be saved and nothing will change and the
image won’t flatten or change without you
knowing. This file is called beach has the .psd at
the end because its being saved a s a
Photoshop file.
People save a file as a PDF sometimes because then they
don’t have to worry if the person they are sending it to
won’t have the right word processor to open it. These files
can be opened with adobe reader which can be
downloaded free and shows the file as a picture so
people can read it without even have the same
programme it was made and saved in. This is a PDF file
opened with Adobe Reader.
