When my photo tour group visited Dunnottar Castle on the east coast of Scotland, fog enshrouded the 14th-century ruins. It was magical. Sometimes it was virtually impossible to see the castle because the fog was so thick. The problem with using a wide angle lens here to include the gorse flowers as a dominant foreground was that it pushed the castle seemingly further away. So, to make the picture look like what I saw, I had to take two shots: the first with a 16mm focal length of the flowers and the grass, and the second with a 35mm focal length of the castle. I used the same lens for both shots -- a 16-35mm wide angle. Using a layer mask in Photoshop along with the gradient tool, I blended the two images together. I then added saturation so the grayish water looked more blue.
