Color Shift Between RAW and JPEG Image in Lunminar 4
Answered
I'm not sure I understand the response in this post: https://community.skylum.com/hc/en-us/community/posts/360006981340-Turning-off-Auto-Adjustment-?page=1#comment-overview
I'm also am not sure why the post was closed so I could comment directly to it. It should still be open.
Background: I shoot both JPEG and RAW. I observe that there is a significant color shift (possibly even some contrast shift) when comparing the JPEG and the RAW file in Luminar 4 that I don't believe is real. This observation is before any editing is done.
The claim in response to the post in the URL above is that this is normal.
I can understand that there might be a wider color palate in the RAW file VS the JPEG because that's why there is a RAW file since it holds more detail then the JPEG. But even so, I am surprised that the color shift is so large between the two file types. I could see that there might be higher dynamic range in the RAW so greater tonality in say the blacks but the shift I see I believe is not real. If we consider the RAW file the standard then what's being implied is that the JPEG is not an accurate rendition of the scene and I just don't believe that. The JPEG may lack the tonal range of the raw and so the dynamic range in the JPEG may not look as good however the shift in the histogram between the JPEG and the RAW just doesn't seem reasonable. What am I missing? I'd like to understand this more, please.

I have sent an email already to support with a comparison screen shot of the JPEG and RAW images prior to any editing.
I am surprised you have not seen that already.
Please look for my email.
I also tried doing the same comparison in Luminar 2018 AND AURORA 2019.
My observation is exactly the same in those versions of Luminar & Aurora as well.
It's like you do some kind of tonal mapping (which I might expect in Aurora but not in Luminar)
A number of different customers/end users have pointed this phenomenon out for some time to the Skylum team.
