banner unit 3

In Unit 3 you’ll be exposed to the skills to use sound, image, and video software, and will also learn how to create and use QR codes (Quick Response codes) to facilitate access to web resources. Much of what you learn in this unit comes from the information and tutorials associated with the projects. You’ll learn by doing!

The goal of this unit is not to simply teach you software names, button pushing and knob twiddling of today’s capable software. The goal here is for you to also learn the science that makes these powerful applications possible. The topics we'll explore include:The goal of this unit is to have you understand the contemporary tools of sound recording and editing, photo editing, and video editing in principle and to develop the skills to use these as they present themselves to you as useful tools in your chosen career.
