I have attached a photo with missing pixels. They can be seem on zoom and appear as a series of white dots slightly below and to the left of the yellow buoy below the most significant rainbow. I have taken quite a few photos with this camera and never noticed missing pixels before. When I looked at the printed 8x10 I though there were white dust specks on the photo. They were easy enough to correct in PP, but what causes this phenomena? Thanks Larry
You know, on second and third thought you guys may be right about the seagull theory. At that distance, there may not have been enough pixel density in the camera sensor to define something as small as a seagull. The yellow buoy above the spots doesn't look that well defined under magnification either. Larry
Seeing the crop my first impression was vertical axis motion blur of something on the water. Missing pixels are a lot smaller than these which are larger than features seen in the image. Could be seagulls or ?? If they were pixels, not only would they be tiny but they can be mapped out. You camera probably already has some dead pixels, just as your memory chips have dead cells which are mapped out in final testing. Stan St Petersburg Russia
The yellow buoy, along with smaller white buoys are placed by beach vendors who rent jet skis. The jet skis have to stay beyond the buoys and away from people. Different vendors may have different colored buoys. Most buoys are white, but the specks in the pic are not buoys and not net floats, as this beach attracts many swimmers, nets and fishing attracts sharks and the two don't mix. Larry
Plus, if that's near a swimming area, what fisherman wants the liability of having a swimmer tangled in his nets?
The important thing is, unless you're seeing these kinds of "spots" on other images, it's likely not camera/sensor related. When I originally posted "seagulls," a magnification of your first image seemed to show irregular white and gray pixels. Made me think of seagulls. The second crop you posted makes the spots look more uniform and regular, more like floats than birds. So, frankly, I'm at a loss to say with any certainty what they might be.
I would just fix the image if the spots are distracting and forget about it.
