Notes

• Kimball: Weta Digital code is very much still in legal land, hope to have news end of week or next week.
• Various pieces required on CI, e.g. current Weta's codebase uses Exiftool.
• Spectral Database
  
  • How do we get people with a tool that can measure sensitivities, e.g. how do we provide instructions to build Lightsaber?
  • What file format should the sensitivities be stored, json?
• Current codebase favours pre-computed matrices but can use optimized matrices, falls back to DNG matrices.
• Question about how to detect non-linearisation portion close to sensor saturation.

• TODO: Create overall architecture diagram so that everybody is up to speed.
