I have had the same thing show up on high altitude shots, I was a mountaineer before health problems hit me like a runaway bus, and while I never had an explanation as to what caused it, using a good quality polarizing filter took care of the "problem". I wish I could remember which brand filter it was, I tried a number of them before I found one that mostly cleared it up.

Thank you. I'll pass that one along.

I don't understand what you mean. There are black specks, but that's not what's gotten replies. There are striations in the clouds. Looks like an alpine sunrise to me.

To the left of the center, you see a tall peak, with a steep slope going down to the right of it, into a high ridegeline. Above and just to the left of that ridgeline, if you zoom in on the image, you will see some transparent circles or roundish shaped artifacts. This is what we are referring to. No doubt it's an aberration created, possibly, by meteoroligcal conditions, possibly blowing snow, something like that.

Let's settle what we're talking about. Is it the whitish fluff below these arrows that I added to a crop of the picture? Download to see it better.

Pretty sure it's compression artifacts or in-camera sharpening or other image enhancement. Similar patterns are all over the rocky snowfields, near every high-contrast edge.

Wingpilot,
Can you or your son look at the original raw file and see these artifacts?

Since the reflection of ice particles are minute they are invisible to the naked eye but the camera sees them. An upward wind would be responsible for its creation and motion which also explains why is is localized in two places and nowhere else.

A polarizing filter would indeed filter some of (not all) this stuff out w/o trouble. The brand does not matter as far as I now but circular polarizing would work best.

So:
- Cause: Ice particles
- Correction: Polarizing filter

Still think it is too much saturation and likely the sharpening effect on mid tones from too much clarity. Looking at the original before PP raw file would help.

That's it,

I don't see them when I download the photo. My guess is jpg format is causing it.

The crop with the arrows I posted pointing to the artifact was made from the downloaded photo. (about 8 posts ago.)

Snow and shadows are strange bedfellows. For instance, if you look not far to the left of the 'artifacts' you'll see two small triangular shapes - possibly young evergreens. The lower one looks like it is holding a broom. Then, directly below the 'artifacts' in a white area you'll see what resembles a polar bear's head; the bear swimming submerged, except for the head, in a river of snow. Just to the right of that appears to be a bird's head.

Oops, the cropping took out what I was looking at.
