"Landscape photography is the supreme test of the photographer - and often the supreme disappointment." Ansel Adams.
As the sky draws our eye into the photograph, we are able to better distinguish the subject since our natural instinct is to take the sky for granted.
The dramatic effect that clouds add to the photo brings about a feel of depth and character. Our mind’s eye better relates to the naturalness of the image.
Black and white photos bring out the wonder and beauty of the sky as a backdrop. In landscape photography the sky adds drama to the story.
