Abstract [en]

Photorealism is what visual effects are all about most of the time. This report entails digital compositing and studio lighting, in relation to Chroma key film material, aimed to give a photorealistic impression.

   One of the identified problems in this report is that compositors may get Chroma key footage where the lighting is done poorly, which means a lot of extra work for the compositors and it might even make it impossible to create the desired end result.

   Another problem recognized is that the knowledge that these professions possess is often tacit, not available in texts or even functionally defined.

   Considering these problems, the purpose of this report is to articulate and try the tacit knowledge found in respect to these research questions:

  • Which factors can alter the photorealistic impression of filmed Chroma key material?
  • To what extent can different factors be altered in the compositing process, for a photorealistic result?
  • How can a photorealistic result from composited Chroma key material be enabled and facilitated, with focus on studio lighting?

  

   Methods used to answer these questions are interviews with compositors, a case study of a small video production, and the production of video clips, including studio lighting and compositing.

   While professionals often write about the importance of consistency in image characteristics between different element that are composited together, this report defines which specific features that ought to be consistent, for a photorealistic result.

   Further findings are focused on the limitations of the compositor; i.e. the features that are possible to manipulate and the features that have to be set correctly when filming in the studio, to enable a photorealistic outcome. Nonetheless, the main focus will be on the features of lighting set in the Chroma key film studio.

   In fact, there are many features that are crucial for enabling and facilitating the compositing of a photorealistic end product. While some of the findings are new, others confirm what has already been presented.
