Selecting spirit levels with appropriate bubble response sensitivity for camera rigs
18 years old. Gear and prices may have changed since.
What the thread found
- Spirit levels vary in sensitivity, with more sensitive levels (lower degree or minute ratings) producing slower bubble movement that can be advantageous for precision work
- McMaster-Carr carries precision levels with different sensitivity ratings measured in minutes per 0.1 inch per foot
- Multiple levels with different sensitivities can be used for different purposes: one for overall monitoring, another for quick adjustments, and a third for fine lock-offs
- Sensitivity measurements can be expressed in degrees or in minutes, where 1 degree equals 60 minutes
- When framing a shot with no true vertical reference in the scene, camera level decisions may need to balance mathematical accuracy against artistic composition
Depends on
- Thread does not clearly resolve the exact conversion between degree ratings and McMaster-Carr's sensitivity measurements
- The specific part numbers and technical specifications mentioned were not fully verified by all participants
- Discussion focuses on Steadicam and cinema camera applications, relevance to other uses may vary
