EDIT: I didn’t remember of this when I made the first tries when received my FP4, so it could be linked to the last A.094 update…
EDIT2: with 12MP the writing “HDR” (High Dynamic Range) is set automatically when I’m pointing at the sky, with 48MP this is not the case → it could be the cause of this difference
Just to follow up, one reason I bought the FP4 was the 48mp picture possibility.
However, as described the pictures become over exposed on a sunny day, but on an overcast day with low dynamic range, the pictures look much better.
Hopefully the quality of the 48mp option improves later on.
Just for information, the 48MP pictures appears quite a lot better after having installed the latest update:
Software Version: FP4.FP3S.A.103.20220221
Security Patch Level: 5th of February, 2022
I just took a few pictures in circumstances where the they would have appeared washed out with no details in highlights.
Here is a test after the update.
