P1 describe the hardware and software used to create and edit graphic images
This is your presentation or document outlining the features of three digital image-related pieces of hardware and two applications.
P2 explain how different types of graphic images relate to file formats
This may have been covered in your A4 and A5 poster task write-up but probably best covered by the file format task showing a JPG, GIF and PNG against a dark background.
P3 demonstrate the use of editing tools to edit and manipulate images
Your A4 and A5 poster tasks, including the explanation of what you did, how and why
P4 create original graphic images to meet a defined user need
The images and logo for the A5 poster task, included in your write-up of it.
P5 modify images as a result of user feedback
Changes you made during the A4, A5 poster task - maybe to original image (e.g. wrong size or no licence for commercial use or just an unsuitable image) or refinements made to which sections you used for the final output or maybe changes necessary to the text featured.
P6 explain the potential legal implications of using and editing graphical images.
Your write-up of licences, copyright and model release form features
M1 compare the limitations of different hardware and software packages used in graphics work
Comparisons and recommendations for hardware and software - a development of the Hardware & Software task
M2 justify the software, tools, file format, image resolution and colour depth used for creating graphic images.
There is a good opportunity to cover all of these in the A4 and A5 Poster task write-up. Alternatively you may refer to a different image editing or creation task where you have utilised a range of tools and had to consider effects of file format on size etc.
D1 evaluate the impact of evolving output mediums on the design and creation of graphic images
This is your look at the future, what output media are being developed, latest technology and the findings from your research of a particular type.
D2 discuss the impact that file format, compression techniques, image resolution and colour depth have on file size and image quality.
Your file format slides, comparing a graphic across formats and colour depths can cover part of this if you have written a good comparison and dealt with colour depth there. In addition, or possibly alternatively, this can be achieved through an examination of either your work in producing the A4 and A5 posters or a different task that provides clear illustration of the effects and enables you to write in some detail, with examples, about compression options and colour depth.
