  • How to maintain consistency throughout your day exteriors
  • The lights I bring on every one of my day exterior shoots
  • How to equalize and balance artificial sunlight
  • How to diffuse the sun
  • How to match a cloudy scenario to a fully sunlit scenario
  • What the proper key to fill ratio is for a natural look
  • How to use negative fill to achieve the proper ratio
  • The differences in output between the 18k and the 4ks
  • How the quality of light varies between the 18k and the 4ks

Day exteriors are some of the trickiest situations to handle as a cinematographer. One minute the sun is out and the next minute Armageddon sweeps over with a thick blanket of cloud cover. But the scene doesn’t stop; they want to keep shooting. Knowing how to properly use negative fill, how to match color temperatures, and what ratio your key to fill is are all important factors in both maintaining consistency and creating naturalistic artificial sunlight for day exterior situations.

Shane Hurlbut, ASC takes you through the arsenal of tools he brings on each of his day exterior shoots in order to maintain consistency. Learn about the proper key to fill ratio for a naturalistic artificial lighting scenario, how to best utilize negative fill to shape and add contrast to a face, and how an 18k varies from two smaller sources with a combined similar output.

Shane walks you through why he prefers one source over the other in an exterior artificial sunlight scenario. Pulling from some of his past feature films, television show and accompanying behind the scenes content, Shane demonstrates the real world applications for the tools he talks about.
