Hi,
As part of the ACES Virtual Working Group on Gamut Mapping, here is a computational Google Colab Notebook about spectral images processing.
CIE 1931 2 Degree Standard Observer - Rendered Spectral Image
Canon 5D Mark II - Rendered Spectral Image
CIE 1931 2 Degree Standard Observer - Chromaticities
Canon 5D Mark II - Chromaticities
I’m planning to refine the workflow in the coming days to be able to scale across many images.
Cheers,
Thomas
