Unknown spots on image
Aug 18, 2018 10:05:31 #
I shot some scenery yesterday and after processing I found that a couple of the images have spots on them that look like dust. I don't think dust is the problem, but you can see the spots in the clouds just above the pond..
Shot with 5d mk 4 and 24-105 L II. Breakthrough CP . 1/15 f11 24MM. Processed in PS Raw. There is no dust on the lens or the filter, and after I discovered these spots I set up a white board and shot some test shots at the same settings, and there were no spots. Also checked several other similar scenes that I shot around the same time and in the same area and there are no spots.
#1 shows spots, while #2 does not appear to have the problem. There was no lens change or opening of the camera between these two shots. Any thoughts or suggestions???

They are possibly insects, with your slower shutter speed elongating them.

I don't see any spots.
If I did, I'd ask if you photographed distant birds?

If you mean the spots in the center of the top image, in the clouds in the image section between the trees? It looks like forest litter (needles, twigs, dust?) just blown into the air. You can almost see it in a swirl. Bugs maybe even.

I agree, possibly dragon flies or Damsels both of which are attracted to water.

The spots I see in the photo look like dust, to me. They actually look like mini fibers. I've had similar specs on some of my images and found that a sensor cleaner fixed the problem. Buy the prepackaged cleaning swabs and that should fix your problem.

Don't see any spots. I did check the calendar to see if today was April 1st??

If you read the OP they appear on the first pic but not the second, definitely not on the sensor or the lens.

To see them you have to download the image and enlarge it significantly, the spots he is complaining about appear in the clouds.

If you look carefully, there are literally dozens of small elongated spots, both in the clouds and in their reflection in the water. Since I don’t see any in the second shot (although there are less white clouds as a background and the exposture is shorter - 1/40 vs 1/15), i’m going to agree with Linda and chgcanon that it must be debris or insects in the first shot.

Did that, still didn't see any spots. But then I am 75 so guess these old eyes can be excused.
OK, GOT IT. I WAS LOOKING TO HIGH.... Need another shot where that spot on the shot is in a clear place. Shoot the sky or a white sheet of paper.

The Visualize Spots tool in Adobe Camera Raw may help you identify the origin of the spots. See this tutorial. After you load Photoshop, you can take the image to ACR for this tool:

Temporary dust that settled on your lens at that point in time.
