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? enter image description here enter image description here

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 enter image description here Image taken on f14 enter image description here

    I'd give cleaning another try after filtering the air in the work area. I also wouldn't use F-numbers higher than F8, unless there is a specific reason to do so (aside from demonstrating sensor dust). You can also try the "Dust Delete Data" function. – xiota Aug 15 at 3:42
