be built into or can be enhancements to editing systems. All tools allow you
to adjust depth by setting and manipulating keyframes. This is a manual
process: the depth team locates the possible issue visually and addresses it
(if possible) using the adjustment tools. Most mainstream editing systems
have some native capability for depth grading. Those which do not are served
by a variety of plug-ins which effectively do the same thing.
5.6.4 Terms
Terms causing most of the confusion in the depth workl ow include:
• good 3D
• depth
• interaxial
• parallax
• maximum negative (far) parallax
• maximum positive (near) parallax
• convergence
• converged
• parallel
• screen plane
• negative Z-Space
• positive Z-Space
Dei nition for each of these terms can be found in the Glossary. Key questions
the depth team can ask about terms for each process area in the depth
workl ow are shown in Figure 5.13.
5.6.5 Targets
Here are some key examples of depth targets:
• Depth Budgets
• Depth Scripts
• Maximum Positive Parallax
• Maximum Negative Parallax
