A lot of great move captured dynamic with wonderful magic colours. I'm amazed that you take so wonderful photos with such a typical camera. That's a proof that the art is inside the artist, not in their tool
i think you don't have to, but if you like to hide these dots than you can use one tool in photoshop wich is very powerfull in this things. Its called "spot healing brush tool" of course you'll find it in your toolbar, its below the crop tool.
Just fit your brushsize to the size of the dots and click on it. The tool will copy the pixels around the dot.
