Part 4 of this series is one that may be a little deceptive. This is NOT a black and white photo. The light from the fog created a silhouette of the trees and the people. The little bit of color present can be seen in the slight lens flare of the sun and on the ground.
This photo is not altered in any way. It was taken with my iPhone 7 Plus. Proof that you don't need a great camera to get great photos. You just need to be in the right place at the right time.
