adjustments for mirrordome

We had some minor adjustments done to improve the looks of our fulldome projection.

  • Moving the mirror up by a few inches more now allows us to bring the horizon a bit lower in the front area of the tilted dome of the theatre.

  • Moving the projector laterally left-right corrected the tilt in the reflected image, where earlier the left side of the reflected image was around a foot higher than the right side - for this, we moved the projector physically to the right.

  • Moving the projector towards and away from the mirror, and adjusting the zoom setting allowed us to reduce the shadow area right above the mirror. Covering a larger area on the mirror makes the shadow smaller and vice-versa.

  • Using the Bright mode instead of Custom mode in the projector, the colours are a bit better though the brightness levels are quite lower. This has to be further tuned.
