I was heading out to a new location for me to shoot some stars, it was a dock along a little lake. However all of a sudden, heavy fog rolled in, and I couldn't see any stars anymore.
Lucily for me it wasn't any wind at all, so I pointed my camera towards the grass along the side of the lake, and my 4 minute exposure turned out really well.
Some of the earlier shots I took just minutes ahead would show the trees on the other side of the lake, but this shot got so much fog that its all hidden. So I didn't have to photoshop anything
