1. Alignment/Geometry
5. Contamination
9. Hyperdivergence
13. Visual Mismatch
2. Luminance/Colorimetry
6. Sync/Genlock
10. Edge Mismatch
14. 2D to 3D Ratio
3. Depth of Field
7. Full Reverse Stereo
11. Partial Reverse Stereo
15. High Contrast
4. Reflections, Polarization, Flares
8. Hyperconvergence
12. Depth Mismatch
Improper vertical alignment of leftand right images
Dust, water, dirt or other particlesin one of the images
Objects are too far back to beviewed comfortably
Elements within a 3D composition that donot match left and
right
Left image is brighter, darker or of adifferent hue than right
image
Left and right images are not time accurate
Left and right eye side edges not matching,either due to the
addition of floatingwindows or beam splitter box
Too many shots in 2D to qualify the show asgenuine 3D
Focus not matching in the left and right eye
Left and right images are swapped
Some of the layers in a 3D composition arereversed left and
right
An element deep inside or far out ofthe window in high contrast
with itsenvironment, creating a double imageon the display
Reflections on shiny objects notmatching the left and right
images
Objects are too close to the viewers eye tobe viewed
comfortably
Elements within a 3D composition are not inthe correct depth to
the scene
Camera/lens not matchedproperly in production
Challenging environment, lenses/mirrornot cleaned thoroughly
Improper camera settings or objects goingbeyond the safe 3D
zone
3D compositing error
Cameras not matched and/or beamsplitter diffraction
Non-genlocked cameras or editing error
Lack of 3D content
Different aperture settings/non-matchinglens focal values
Data management or editing error
3D compositing error
Refresh rate of the display device/partialseparation of left and
right images by the3D glasses
Beam splitter polarization, camera angles
Improper camera settings or object goingbeyond the safe 3D
zone
3D compositing error
Geometry realignment
Dust removal techniques
Pull convergence forward or compress the3D space
Fix composition. Cannot be fixed onthe final image without
significantpost-production work
Color adjustment
Sync: Re-edit. Genlock issuescannot be fixed without
significantpost-production work
Remove floating windows
Replace non-stereo content withstereo content
Cannot be fixed without significant post-production work or
blurring the focusedimage to match
Swap left and right images
Swap incorrect layers in compositing.Cannot be fixed on the
final image withoutsignificant post-production work
Reduce contrast, change convergence orcompress the 3D space
Cannot be fixed without significant post-production work
Push convergence back, or compress the3D space
Fix composition. Cannot be fixed onthe final image without
significantpost-production work
