I believe they are hot pixels, which can appear if you are photographing with long exposures or using a very high ISO.  It can happen with any camera and can come and go randomly.  The easiest way to deal with them is to remove them in post processing.  It is always best to review your images at 100-200% magnification before submitting, so they should be easy to spot and remove then.

 

The filter can help with the overexposure as well as increasing your shutter speed or reducing your ISO.  With the amount of noise in your image, you probably had the ISO fairly high.  You may want to take multiple shots at different exposures and blend them together to get the result you need.  Good luck with your reshoot.

Hi @Víctor Manuel2470047463k6,

I like your photo content. In itself this is a nice shot. However, I get the feeling it was taken with a drone cam with a fixed aperture or one with wide settings (low f-stop). There are a lot of lost details in your photo.

Your subject need to be sharp.

      In addition to @Abambo comments, you also have a lot of random coloured pixels in your image.  The sky is overexposed along with the light reflection in the water - there is no detail in those areas.  Take a look at a portion of your image at 100% magnification, and it's easier to see some of the issues.  It's always important to review your images on a large screen at full magnification before submitting.

        Si es cierto que aparecen pixeles con colores. ¿Se puede saber porque aparecen?

        El cielo y el mar aparece muy sobreexpuesto pero es que esta el sol justo ahí. Probaré la próxima con un filtro nd mas potente a ver si soluciono la sobreexposición. ¿Podría ser, verdad?

        Muchísimas gracias.

          You need to look at the picture at 100% and 200%. You see that there is a lot of noise and the picture is out of focus.

            Es muy cierto.

            Al 100% se nota la perdida de calidad en muchos puntos y al 200% mejor tirar la foto a la basura jejeje.

            Muchísimas gracias.

              At 100% you will see sharpness problems, and at 200% 0r 300% (don't do in betweens) you see noise and artefacts (and probably hot pixels if you took well enough). If you see artefacts, you need to address them. If there is noise, you need to carefully address the noise. But if you have an out of focus issue, that is most likely not possible to correct, except, if it is mild. If you downsample a picture, you reduce the resolution, but often, you also reduce issues. If you have a very high-resolution picture, it may be worth a try.
