Abstract: In recent years, an increasing number of studio and independent productions have begun using cinematic style, Single Large Sensor (SLS) cameras in production, especially for special events and high-end live shows. The most compelling reason why productions want to use SLS cameras in production is that the larger sensor provides a narrower Depth of Field (DoF) for the same framing than a 3-chip camera, which helps focus the viewer's attention. To better accommodate that demand, it is essential to understand SLS operational boundaries in traditional broadcast environments. DoF, image quality and subjective viewing tests help assess those boundaries in typical conditions, with physical as well as digital backgrounds. While their use is opening new creative avenues, SLS cameras pose significant challenges in traditional productions: In certain scenarios, it's impossible to keep proper focus on the action, for example. Providing deep focus with SLS cameras requires significantly more light, gain or less magnification than 3-chip cameras, which can be an issue. Another unexpected issue is the Moire effect generated when two different patterns are interfering with one another. This was observed when the Bayer pattern of the SLS camera interfered with the RGB pattern of a micro-LED digital decor or set screens. This paper delves into these issues and provides operational parameters and guidance on how to deal with the technical challenges arising from the use of SLS cameras in broadcast, so that creatives can enjoy the benefits of a cinematic look without experiencing too many technical setbacks.
