Above are some examples of Fulldome master images showing the level of distortion required to compensate for the 36o viewing experience in the planetarium dome. The 'sweet spot' is the name given to the spot between 35 - 45 degrees from the bottom front of the hemispherical viewing screen in a planetarium with a forward facing arrangement. This is the natural focus for the eye of the viewer and can be used and manipulated in the production of the work.
