1 Unit 37: Digital Image Creation and Development Unit code: Y/601/6721 QCF Level 5: BTEC Higher National Credit value: 15 Aim 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. 211

5 Guidance Links to National Occupational Standards, other BTEC units, other BTEC qualifications and other relevant units and qualifications The learning outcomes associated with this unit are closely linked with: Level 3 Level 4 Level 5 Unit 30: Digital Graphics Unit 35: Digital Graphics for Interactive Media Unit 37: 2D Animation Production Unit 11: Digital Media in Art and Design Unit 12: 2D, 3D, and Timebased Digital Applications Unit 13: Multimedia Design and Authoring Unit 14: Website Design Unit 38: 3D Computer Modelling and Animation This unit has links to the Level 4 and Level 5 National Occupational Standards for IT and Telecoms Professionals, particularly the areas of competence of: Human Computer Interaction/Interface (HCI) Design. Essential requirements Centres will need to provide access to hardware, software and peripheral devices, to enable learners to gain practical knowledge and skills. Employer engagement and vocational contexts There is the potential for centres to offer a live project or employer-led brief, where the requirements of the unit are addressed through a set brief that identifies real and tangible needs. Learners should be encouraged to work through the different stages of the set brief through presenting images and evaluating fitness for purpose of their ideas generation and digital developmental work, as well as their final outcomes. 215
