I think that will help with this image, to show a bit more of the colourful details in this image 😉 May 16, 2017 at 23:15 #15242 van OverzeeParticipant posts: 142 Ha Mabula, This is how it looks after using the light polution tool. The pictures were taken in the direction of Nice. You could see a lot of light on the horizon. This really helped. Thanks, Hans 4 people like this.
