Sony A7R IV Raw File Support in Adobe Camera Raw is Preliminary, Problematic
Adobe Camera Raw Support for Sony A7R IV raw files is preliminary.
Update September 19: support is now finalized.
Color rendition is way off for the A7R IV, such as tint needing to be +25M to +35M and white balance is off too. Not to mention there being no camera profile.
I am unsure how to proceed showing much work since comparing the Sony A7R III to the Sony A7R IV is inappropriate with no solid camera profile.
