I’m working on Base Light with working colour space ACEScct/AP1, DRT is ACES RRT1.1+. ,Viewing Colour space DCI:2.6Gamma/P3DCI. the raw looks crushed and saturated. It has all the latitude to grade and get the desired information in the image. But for the client who’s not familiar with the ACES workflow as they have been working only on the LOG workflow finds it difficult to see the RAW crushed and Saturated as their first image to start the grade.
Has Anyone Experienced this conflict before? How should One Reslove this Issue.
I can’t exactly imagine what your definition of crushed and saturated is but if the display and viewing condition matches the view transform and it doesn’t look roughly as it did on set maybe there is a mismatch on the input side where the footage is flagged with the wrong color space and gamma.
If the color journey is correct but on set they used the “default” viewing LUT of used camera vendor you could reduce contrast a bit on the whole timeline to more closely match it but that’s just a suggestion.
Viewing log footage ‘as is’ is very bad practice no matter what because it doesn’t provide you any useful information in relation to what was captured.
Bear in mind that viewing log is still just one particular encoding of the scene-referred data. It is not “raw” even though many people like to think of it as such.
However viewing log temporarily can be useful to examine the highlight and shadow detail without an Output Transform applied. In Baselight you can hold down Shift when choosing the Viewing Colour Space, to reveal all the hidden colour spaces. Then you can choose a scene-referred log space, such as “ACEScct: ACEScct / AP1”, or the source camera log encoding, which will bypass the DRT.
But DO NOT then use that as a start point for grading. It is only a technical tool for checking the footage. You must switch back to the appropriate display-referred viewing colour space, which will then apply the DRT.
As @Shebbe says, if the image looks “wrong”, as opposed to “graded” with the DRT applied, then something may be wrong with your Layer 0 interpretation of the footage. Double-check the legal to full scaling of the source if it looks more contrasty than you think it should as a start point. Viewing as log and checking the black level in the image against the black level marker in the Baselight histogram can be useful for this.
