Welcome to 3D!
1. Be meticulous about alignment.
2. Try to avoid or mediate high contrast subjects
3. Wide angle lenses are friendlier to 3D capture and delivery
4. Slower longer cuts are friendlier to 3D edits
5. Pace your depth
6. Compose your shots with an eye toward Z‐axis placement of all objects
7. Keep your Camera moving at all times [when possible]
8. Limit the use of Gimmicks
9. Be careful regarding “window edge violations” particular at the vertical edges
10. Greater than normal depth of field is friendlier to 3D
11. Support your Stereo Depth Cues
12. Binocular Symmetries
13. Scale the 3D Parallax, to the Final Size of the Movie or Display, “Computer or IMAX”?
14. If toeing‐in of the optical axis is used then the background at infinity must be limited
Composition of 3D Shots
1. Think Deep – Look at each element in the frame and determine how it will play out
2. Do not violate the edge of frame
3. Vary the use of depth to allow the audience a rest period, from deep to more shallow
4. For a more immersive experience use a deep depth of field
5. Make sure that you review your material on the intended Target Size Screen
6. Avoid Divergence in your projected imagery
7. Pay attention to how the edit of your project will affect the audience
8. Convergence is almost always set on the subject of greatest interest
10. Interocular and Convergence should vary dynamically throughout the Movie
Rules for the Road
Do’s
1. Challenge everything you were told about in 3D
2. Check visually your work in 3 D on the large 3 D Monitor
3. THINK 3D
4. Go see every Movie you can in 3D
Don’ts
1. Don’t forget your Stereo Depth Cues
2. Don’t make the 3D Movie if the Story is bad
3. Don’t think “we will fix it in POST” Stereo mistakes cannot be fixed easily in POST
4. DO NOT HARM
4. Don’t hurt your audience with bad 3D!
15 1. Think Deep
