In landscape photography the weather isn’t always in your favour, but you can add impact to your images by looking for subjects that have good contrast. You can then balance your composition using the areas of light tones and the areas of dark tones.
The bones of this shipwreck were poking up out of the sea, and the contrast between their dark tones and the greyness of the sea and the distant cliffs made the image stronger.
With this image, looking through holes in a coastal rock, I used the dark areas of unlit rock to frame the light areas of sunlight bouncing off the sea. The extreme contrast has made it much more of an abstract, almost map-like, image. It could even be crunched up silver foil on black velvet.
