Any idea what these strange streaks are?

That works.





All four channels are blown. All bets are off then.

In my book, it is OK to blow irrelevant highlights. The "leakage" of blown highlights into shadows in the form of stripes is strange.

P.S.: it occurs with LrC and C1.

Histogram of the area with problems:




ACR defaults


+100 shadows


+100 shadows, blacks


+100 shadows, blacks; -100 whites.

This could be PDAF striping. I would suggest not blowing highlights adjacent to dark areas that you may wish to boost.

Bloody PDAF striping. I wish MF cameras were without PDAF.

OP's framing is not exotic; it is quite a typical framing. I wonder if it is reproducible or if it happens very rarely.

Yes, that's why I brought it up - I feel that I've taken dozens of shots like this and never noticed this problem before so it really surprised me, so in my experience it's not (yet) reproducible and indeed is rare.

But maybe I haven't blown the highlights and boosted the shadows quite as much in those other shots. And if it's related to the PDAF sensors then maybe this shot was just the bad luck of the draw and if I'd angled the shot a degree differently it wouldn't appear. But I think Jim is correct that when the highlights are blown like that, there are no guarantees.

Thanks,
Sterling
