You would not believe how many dust spots I had to remove from this photo :) But the reason is simple. My ND filter is in a horrible condition, since my trip to Paris few years ago (not the last one), when while I was moving to a new location, the ND filter got lose from the lens, and feel onto a road. While the glass did not brake, it did get damaged, and can’t really be fully cleaned anymore. But it does work, even if I should think of a replacement soon. And I think I will also do a post about how to remove dust spots in Photoshop, maybe tomorrow :)

This is a HDR from 5 exposures, created in Oloneo Photoengine, finished in Photoshop.
