Exam-style question
Try this first
A school wants to create both a logo for its website and a digital photograph for its prospectus. Recommend whether each should be created as a vector graphic or a bitmapped graphic. Justify both recommendations and discuss a relevant disadvantage for each chosen approach.
Model answer
What a good answer should say
- The logo should be created as a vector graphic.
- A logo is usually based on clear shapes and may need to appear at several sizes, so vector graphics allow it to be resized while keeping its edges sharp.
- A relevant disadvantage is that vector graphics are less suitable for representing the complex detail and natural colour changes of a photograph.
- The prospectus photograph should be created as a bitmapped graphic.
Explanation
Why this works
The recommendations are justified by the nature of each image and by the likely need to resize the logo. The answer also recognises that neither approach is universally best: vector graphics are strong for shape-based images, while bitmaps are strong for detailed photographic images.
