Strong foregrounds often make strong images. In landscape photography that is usually true if that strong foreground ties with something further back or leads the viewer into the image. Such images are often taken from lower down (see my blog from two weeks ago about elevation). Let's look at an example taken in Zion National Park.

The foreground detail is very strong. The rocks and water are interesting to look at. I can just sit here and look at the interaction between the water and the rocks for ages. I used a slow shutter speed to enhance to flow of the water to create a strong foreground. This foreground also leads the viewer into the image. The trees on both sides seem to be leaning inward. The rock face works to also pull the viewer to where the water is going.

          Yes, it is a nice scene, but what makes this scene really nice is the strong foreground. Once again, when you get to a scene, look around and choose your vantage point carefully. Ask yourself, which vantage point is going to give me the strongest foreground? Look for rocks or plants that are different from the surroundings. Look at the water and ask yourself which area has more little rapids than another and how can I use that to create a strong foreground?

          Really pay attention to your foregrounds.
