Night mode on Samsung Galaxy Z-fold 5, long exposure. No filters or anything. As others have said, it was more of a light haze to the naked eye, but long exposures told a completely different story. I took about 30 pictures, but these were some of the most clear/crisp.
The last one is while the outside landing lights are on.
I have seen similar suggestion levels including 100% in Vegas, Seattle, and other large metro areas.
If I saw a 30% option described by the establishment as "soso", I would strongly consider stepping away "to the bathroom" forever.
