    "abstract": "Many competing factors must be evaluated in order to optimize the visual theatrical presentation. For example, considering only visual factors, when choosing the projection screen one must consider brightness, brightness uniformity, dynamic range (contrast ratio), and uniform field contrast ratio (screen texture, perforations, and speckle). Notably, the brightness uniformity is especially difficult to address because it varies from seat to seat depending upon auditorium geometry and screen curvature. Furthermore, the brightness uniformity requires some form of multipoint measurement that must be analyzed to compare different configurations. We will present both modeling and measurements of screen brightness and brightness uniformity. We will then introduce both a seat and an auditorium “Q-Factor” to quantitatively compare the brightness uniformity between different setups. We will then use this metric to define an optimum screen curvature.",
