By tilting the camera down and placing the mountain in the upper part of the image, you’ll take advantage of the lens’ distortion and make it appear more like what you’re seeing with your eyes. Simply put, the lens’ distortion on ultra wide-angle lenses “stretches” anything which is placed in the top of the frame, giving the impression that it’s bigger.
Though the conditions are quite different, notice how the mountain changes in the example above. On the image to the left, the mountain has been placed further down in the image and while it’s still an important feature of the image, it doesn’t have nearly as big of an impact as it does in the second image. By placing the image in the upper part of the frame it’s been distorted and is an even more dominant part.
Taking advantage of the distortion means that you’ll include more foreground, though. So make sure that you find some interesting lines that benefit the composition.
Pay Attention to the Corners
One of the challenges of using an ultra wide-angle is that you often have a lot of information within the frame. With a lot going on, it can be easy to forget the smaller details such as paying attention to the corners of the frame.
After capturing an image, I tend to always look at the image preview and zoom in. By doing so, it’s easier to notice if there are any minor errors that will be more visible once you view the image on a larger monitor.
