Unit 30 Digital Graphics

Create the file formats section of your report, explaining how different types of graphic images relate to file formats. This should include sections explaining differences between vector and raster images with some examples of file formats that can be used to save them to storage medium.

P1: Describe the hardware and software used to create and edit graphic images P2: Explain how different types of graphic images relate to file formats

For M2, learners must justify the choice of tools, file format, image resolution and colour depth used when creating the images. The ‘justification’ asks for the reasons why those specific items were used.

For D2, learners need to use different file formats, different compression techniques, different image resolutions and different colour depths, and for each show the final file sizes and the differences between them. Some will, of course, be more significant than others. Learners can receive guidance in selecting each attribute type but thereafter must produce the files and the comparison independently. It makes sense for learners to reflect on what they have used in creating the three associate...

For P1, learners should describe the role of the components of a given computer system in the production and manipulation of graphics. Learners could produce a series of information leaflets to cover at least one item from each of the groupings in the unit content.

For P3, learners could capture images using a digital camera, or use a pre-existing image to edit. Tutors should supply learners with a user need. Learners must manipulate images to achieve a pre-defined effect which should be related to a defined user need, for example to be more eye catching, or to draw the attention to a specific element.

M1 is a comparison. Normally a comparison would consider both good and less good points, but in this case only the limitations are being compared. Within the remit that the hardware and software must relate to the production of graphics, learners can select any hardware devices and compare the limitations of those, and then select any software packages and compare their limitations. Whilst it is more appropriate for learners to select the items themselves, the tutor can direct them to devices an...

For D1, learners will research the ongoing changes in, and additions to, output media and the effect this has on the creation of graphic images.
