Yes, That is what is happening.Two points -
1. I created a macro in Photo persona and applied the macro in Batch on RAW files.I get different results when I try to process same image but by directly applying the macro
2. In general when I try to import the RAW NEF files in Affinity, and I find them way too underexposed and flat as I have shared in my original post. My main issue with this post here is, I want the RAW files to come as I see on my camera - Z6 orr how I see it on default RAW viewer on Windows 10 Photos app.
The first pic underexposed one is in Develop Persona in Affinity without any changes and second photo is default RAW viewer in windows 10 Photo App without any changes.
