Lynda Learning Digital Media Principles [TUTORiAL]

If you're a self-trained designer, photographer, CG artist, audio mixer, video editor, or motion graphics artist, you have a good grounding in the tools you use, and you know the results you want, but you might not know how the technology you're using really works. It's a transformational moment when you gain a deeper understanding of the way digital images, graphics, video, and audio work.

Every day you're adjusting pixels and sound waves that have been captured, created, or rendered digitally. Grasping what is really happening when you work with digital media allows you to improve your skills faster, communicate effectively, and collaborate more easily. This course removes the mystery behind terms you've encountered, enhancing your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo be supplied in vector or bitmap form, and more.
