1. Pixel and Resolution
Pixel and resolutions are used in monitors to show images. A
monitor can contain thousands of pixels, the amount to pixels is
called the resolution. Resolution can vary depending on whether
the monitor is wide screen or 10:8.
The most common resolutions are 720p or 1080p, These
numbers are the number of pixels up the Height of the monitor,
they are usually accompanied with the amount of pixels across
the length to create a full screen e.g. 1080x1920

2. Vector and Raster Images
Vector images use paths to define an
images. Such images are created in
Adobe illustrator, These images scale
up and down very well because they
are based on paths’ Fills and
thicknesses not pixels. Raster images
use pixels and are often used in
photographs or photo-real images,
these images to not scale up or down
very well, Doing this just enlarges the
pixels and can lead to pixeliseation.

3. File Formats and Uses
There are many types of File formats, and each one has a
specific use. For example: JPEG, PNG and GIF are all used to
show images. JPEG’s are used on websites, there lower
quality allows the webpage to load without too much strain
on the internet connection. GIF’s are also used mostly on
the internet as the allow for several images to be played in
sequence, Perfect for making a webpage feel more alive.
PNG’s are higher quality Images, they can be used on the
internet, but there main use if for Photography and
printing.

4. File Formats and Uses
Specific application File formats are just as important if
not more important the universal ‘JPEG, BMP and GIF’
that we know. The ‘psd’ (Photoshop Document) allows
you to edit various types of file formats and save the
new images created without committing to a specific
format. Psd files are closely

5. Compression
File compression consists of encoding
information so the new encoded file uses less
bits than the original. Simple compression tools
are included as standard on most operating
systems, For example windows ‘zip’ function.
External compression applications are available
online, for example ‘7-Zip’ or ‘WinRAR’

6. Optimising
Optimization of files is important to maintain a high
speed of transfer and Quick launch times.
Optimizing a program usually means rewriting the data
to improve the efficiency of retrieval. A good way of
doing this can be incrementing files of virtually the
same use, for example
• Tree_001
• Tree_002
ect…

7. Storages and Asset Management
Managing assets dose not seem difficult, but it can get out
of hand with the more files you have. The storage of these
files must be safe, secure and accessible. for example, when
taking digital photos, the images are stored on a temporary
memory card, this card can b easily lost and are often not
that big, not Ideal for storage.
The photos can be transfer on to a desktop computer, this is
safer, as it’s almost impossible to lose a desktop PC. The
files can then be backed up on an external hard drive of into
cloud storage. Aswell as ensuring the files are safe, they
must be easy to find, especially if you have thousands, it is
wise to organise these files on folder with dates, of themes.
