Image Processing Basics
Shake gives you explicit control over every aspect of
image processing. This chapter covers the basics of image
processing, and how to control the flow of image data in
your own Shake scripts.
About This Chapter
This chapter covers important information about topics that are fundamental to
compositing within Shake.
These topics include:
• Resolution handling via the Infinite Workspace
• Bit depths
• Alpha channel information
• Premultiplication
• Logarithmic colorspace support
If you’re a new user, or an experienced user who has always wondered why some
things don’t seem to turn out like you’d expect, it is well worth your time to review this
information to better understand and control how images are processed in your scripts.
Taking Advantage of the Infinite Workspace
One of the most powerful features of Shake is the Infinite Workspace. Shake optimizes
image processing by rendering only the portions of each image that are currently
exposed within the frame, no matter what the original resolution.
