Unit 37 Digital Image Creation and Development
This unit aims to develop skills and understanding in sourcing, creating, developing and managing digital images for specific purposes.
· Unit abstract
In this unit learners will work with digital image systems and equipment to produce digital images to a specified brief. They will learn key aspects of digital practice such as file naming conventions, storage, compression and output. They will also work with a range of input devices and software tools.
Learners will be encouraged to explore approaches to developing digital imagery that incorporate creativity and sound technical skills. Learners will evaluate their response to the set brief, and consider areas such as copyright and legislation in commercial and non-commercial contexts in contemporary practice.
Delivery will be primarily practical with the provision of demonstrations of software and hardware. In addition, theory sessions will facilitate learning in some topic areas, for example file size, formats, resolution and compression.
Learners will be encouraged to adopt an experimental approach to generating imagery. This will enable learners to broaden their creative experiences and their understanding of the creative and potentiality of digital imaging systems.
Tutors will provide a set brief, or facilitate learners in developing their own set brief that meets the requirements of the unit. Learners will prepare designs for images, capture images, save appropriately, and present evidence that demonstrates their understanding. There will be opportunities for learners to focus on the critical evaluation of their own work. This may involve peer group and/or tutor presentation and discussion.
It is anticipated that a major proportion of this unit will be practice-based,
and thus learners should demonstrate competent use of digital imaging systems
in the production of practical work. Thus documentary evidence for each outcome
will include images, their evaluation, and supporting material that
demonstrates knowledge and understanding.
· Learning outcomes
