Thank you for your support,
For example, if I have the Arri Raw which has been captured in AlexaLogC
A- I transform the color with OCIO color management system to ACES STM2065-1 (scene linear)
And view in sRGB monitor using sRGB(ACES) response curve
B- I transform the color without using OCIO color management to Linear
And view in sRGB monitor using sRGB response curve
From my understanding,
A and B will look different because of the sRGB(ACES) Response curve is different from legacy sRGB response curve
A ACES Linear AP0 has a wider color dynamic range than B Linear image data and that make the sRGB response curve display differently.
Please correct me if any of the statement I did above are wrong and please explain.
I have a test with ARRI raw file by
Read The file into nuke and specify the IDT to Raw and display in sRGB color response curve and using nuke default color management (linear)
Read the file into nuke and specify the IDT to raw and Display insRGB color response curve and using OCIO ACES1.1 color management (ACES Linear)
The result is
1 - The image display differently in the same monitor
Why the image display differently since they both using the same color responses curve (sRGB) ?
2 - I sample the same pixel at exactly the same X,Y coordinate and they have different value.
Why the value is different since they both are the same image data reading as a raw data?
Is it because the working color space is different?
Which is mean Linear ACES working space is complete something different from
Nuke default Legacy Linear working color space ?
And what exactly is the differences between both of them?
I have to apologize if asking questions like a fool here.
I tried by best to understand Color science as an artist.
I have a homework from my boss where I need to have a better explanations About the differences between ACES linear and Legacy Linear workflow ( please suggest a suitable terminology if possible)
