Hello all,
I'm trying to get my head around ACES and am wondering what ACES specific linear data/files might be and why they should exist.
I am from a VFX background and I have always understood Linear to mean that the data/image is just a physically correctly captured and stored. Basically it should just be a measure of how many photons hit that sensor cell/pixel. (ignoring debayering here)
How can anything be more linear than that?
On this page about ACES they talk about some ACES specific linear EXR's.
http://shootdatapost.com/blog/2014/5/16/aces-in-10-minutesWhat would be different with this format and say an exr derived from a DSLR raw file, or a exr from a compunded set of raw exposures combined for higher luminous dynamic range?
When I look at ILM's openEXR page there is no new exr format and the latest one is from 2014. I see no mention of ACES.
http://www.openexr.com/index.htmlDoes anyone know what the difference between traditional Linear EXR and ACES Linear EXR would be?
Cheers
Fred
