There are plenty of great articles on how to improve your landscape photography (like this and this). Usually, when I’m going out to shoot a landscape, the tripod comes along. If there’s water, then the tripod is a must because it allows for longer exposures.
After taking the first few shots of this session, I realized that the body of water and colorful sky was kind of bland. The two photos below show how a composition can become a little more interesting when you take a step back.
In the photo on the right, I decided to walk a little further back to capture the water hitting the rocks. Also, since the sky became darker, a longer exposure was possible, creating the misty effect.
