Factors
to consider when selecting graphics to be used in a multimedia project:
a) Purpose:
- Avoid using images for “filler” or when
they have little in common with the overall
message or purpose.
- A common mistake is to trivialize
products with cartoons that can be distracting to the
viewer.
- If multiple images are used, make sure
they reflect a common message such as providing the user with an example or an
illustration.
b)
Quality:
-
Any image used in a multimedia product should reflect the overall quality
desired of
the entire product.
-
The image colour
depth has to be considered, especially for applications that will be
displayed on systems using a lower colour
capability.
c)
Cost:
-
The cost of a graphic is directly related to its purpose and quality.
-
Copyright and ownership of graphics will determine who is to be paid
