1. Task 1
Resolution
This depends on how clear and sharp an image is, you hear
resolution used a lot of the time to describe monitors, printers and
bit-mapped images. The more pixels there are in an image, the more
detail the image can be displayed with. The fewer pixels, the less
detail the image will have in it. Different ways to display an image
would be to either have it on screen or have it in print. When
preparing an image you will need to know what resolution to scan or
size them to, there is an optimum resolution for each and it is very
easy to determine. The standard for screen displays is 72 PPI and the
standard for print is 300PPI. Image resolution is simply the number
of Pixels per Inch (PPI).

2. Pixels
In digital imaging, a pixel, picture element is a physical point in a
raster type image. Pixels are the smallest controllable element of a
picture represented on the screen. The address of a pixel
corresponds to its physical coordinates. Each photo site or pixel on
the sensor absorbs photons and releases electrons through the
photoelectric effect. The term pixel is actually short for Picture
element. The small little dots are what make up the images on
digital. The screen is divided up into a matrix of thousands or even
millions of pixels. Even though pixels can only be one individual
colour but an image can be made out of so many pixels which make
the colours that you see in an image.

3. Vector and Raster Images
Graphics come in two types, raster and vector.
Photoshop, and Paint shop Pro are all examples of
raster programs. Raster images are described by an
array of pixels that each has a given colour and
intensity value. Vector images are described by
mathematical lines, curves, and fills. Adobe Illustrator
and Corel Draw are examples of vector programs.
Both raster and vector images have their advantages
and disadvantages. Raster images look more realistic,
but vector images print more easily and can be
infinitely scaled up or down with no loss of quality.

4. File Formats and Uses
JPG files are normally used for digital cameras - because JPG
heroically compresses the data to be very much smaller in the file.
However JPG uses loosely compression to accomplish this feat, which
is a strong downside. A smaller file, yes, there is nothing like JPG for
small, but this is at the cost of image quality. In general today, JPG is
rather unique regard, using loosely compression allowing very small
files of lower quality, whereas almost any other file type is lossless
(and larger).
TIF is lossless, which is considered the highest quality format for
commercial work. The TIF format is not necessarily any "higher
quality" per se and most formats other than JPG are lossless too.
TIF does most of anything you might want, from 1-bit to 48-bit
colour, RGB, CMYK, LAB, or Indexed colour.
GIF was designed by CompuServe in the early days of computer
8-bit video, before JPG, for video display at dial up modem speeds.
GIF always uses lossless LZW compression, but it is always an
indexed colour file, which is poor for 24-bit colour photos. PNG
and TIF files can also optionally handle the same indexed colour
mode that GIF uses, but they are more versatile with other
choices too. For graphics of only a few colours, GIF can be much
smaller than JPG, with more clear pure colours than JPG.
PNG can replace GIF today, and PNG also offers many options of
TIF too. PNG was invented more recently than the others,
designed to bypass possible LZW compression patent issues with
GIF, and since it was more modern, it offers other options too. One
additional feature of PNG is transparency for 24 bit RGB images.
Normally PNG files are a little smaller than LZW compression in
TIF or GIF, but PNG is perhaps slightly slower to read or write.
This is used less than TIF or JPG, but PNG is another good choice
for lossless quality work.

5. RAW files are very important of course, but RAW files must be
processed to regular formats (JPG, TIF,etc) to be viewable and usable
in any way. However, the point is that RAW offers substantial benefit
in doing that.
Image Compression
Image compression is minimizing the size in bytes of a graphics file
without degrading the quality of the image to an unacceptable level.
The reduction in file size allows more images to be stored in a given
amount of disk or memory space. It also reduces the time required
for images to be sent over the Internet or downloaded from Web
pages.
Image Capture
This is a basic this that an amateur photographers need to
understand. It is built up of 3 main elements;Lighting mostly working
in amateur photography will be happy just to get an image that is in
focus, but the reality is that lighting makes photography,
Organization Digital photography is not as difficult to deal with as
film photography during the editing phases, but you still have to
manage the files, Cleaning it may seem like common sense, but a lot
of amateur photography is ruined because the photographer did not
keep their camera clean. These are the main elements of image
capture.

6. Optimising
This is when you optimise an image to make it the best that it can be
also it can make corrections and providing the image for final
delivery. This is making an image perfect or to the max detail and
quality that you can.
Storage and Asset Management
Generally the asset being managed is collected and stored in a digital
format. There is usually a target version - referred to as essence-
generally the highest-resolution and highest-fidelity representation.
The asset is detailed by its metadata. Metadata is the description of
the asset and the description depth can vary depending on the needs
of the system, designer, or user.
