For some reason, the quality of my photos has worsened (tiny dots appeared). When I zoom in on the new photo, especially in the fog or clouds, I can see these little dots. They were present in the old photo too, but they were less noticeable. The old photo was taken about two months ago, while the new one was taken just a week ago. Both photos were taken with a DJI Mini SE drone.
That’s grain. Lower your iso

Then the person who posted this will complain about blurry photos in low light.
It’s a different situation. The first photo is in low light, so the drone raises the ISO to make it brighter, but that reduces the quality. The second one is taken in better lighting.
Time to understand what your settings are for.
Check out the exposure triangle.
It’s noise. The lack of light causes the ISO to increase, which leads to more noise and dark parts that are naturally noisy.
The image sensor picks up noise, which means random signals that act like light. When there’s enough light, the sensor captures it quickly, and there’s no noticeable noise. But in low light, the sensor takes longer to gather light, making the noise more noticeable. If you shoot in total darkness with a long exposure, all you get is noise.

Thanks for explaining this clearly.
Come on, do some learning about your equipment.

That would require them to put in some effort, which most people don’t want to do.
Check your iso settings.
That’s called noise or grain, and it’s because of low light.
You’re dealing with two different lighting situations here. That’s probably the main difference.
Are you using an ND filter in low light?
It’s noise. And noise is more noticeable in photos like the first one because the sky is pretty uniform, so it shows up more. Also, I have to ask, did you edit these photos in something like Lightroom? Editing can bring out noise, especially if you adjust the exposure. Finally, it’s okay not to understand noise. We were all beginners once.
