4. Nominal Camera Tilt Visible Horizon Non-Visible Horizon Implied Horizon Rolling Text Plane

5. Nominal Camera Tilt 00 Degree Tilt 10 Degree Tilt 20 Degree Tilt 30 Degree Tilt

6. Action & Text Safe Area

8. Periphery Out of View

9. Gamma/Color Consistency

10. 2.2-2.5 Gamma White Point - 6500 Kelvin

11. Gamma/Color Consistency Lack of understanding Too many projectors to calibrate Cost of calibration hardware Adjustability of projectors Image is percieved as less bright

12. Star Decimation

13. 3600x3600

14. 2200x2200

15. 1536x1536

16. 1024x1024

22. Star Decimation 4 pixel stars hold up well Filtering methods yield comparable results on non-moving images. Higher Magnitude (dimmer) stars vanish If the starfield is the main subject of the show, more care should be taken.
