I had open my lens of Canon EOS m50 while I am on a ferry to a local island near by. Once I reach home I saw few spots on sensor which doesn't look like dust. I used swabs and cleaned the sensor it become clean but even if I took pictures on high aparture value like f20 and above I can see light spots still exist and which I am not able to remove using wet cleaning. Any idea what should I do now?
So here I have 2 images. First one taken on f30 of my white kitchen wall and same image I did a dehaze in light room. After dehaze the dots are visible. Image taken on f32 Image taken on f14
