depth adjustments affect geometry and geometry adjustments affect depth.
If the geometry in a shot or scene cannot be i xed cost-effectively, then the
shot should not be in the depth workl ow, or any other workl ow.
We assume in this chapter that your shots have proper (or corrected)
geometry—imagery your depth grading has no perceptible geometry issues
or that they have been resolved. In fact, one of the most important things
a person in the stereography role can tell you is whether an issue is related
to geometry or depth or something else. Some imagery requires no or only
minor geometry correction. Some single-body 3D imaging systems can, in
capable and experienced hands, generate technically correct 3D frames “right
out of the camera.” If you are fortunate enough to be working with imagery
acquired by a 3D-aware team using reliable imaging systems, then your show
will sail right through the depth workl ow, requiring minor creative tweaks
and enhancements to on-set depth choices.

3D post teams have the right to expect image acquisition teams to deliver
imagery with depth within the creative parameters of the show. Still, even the
most experienced 3D productions run into resource limitations, equipment
