When the texture is strong the color can take a rest.
The most interesting thing by far in Hawaii Volcano National Park for me was texture. There was a lot of it and a lot of different kinds of it. While the color was lacking: either black of lava or green lush of the tropical forest. The sky was mostly overcast and not in an interesting way.
So, I photographed texture. And the best time to do it is during sunrise or sunset when the sun is low. That is if it shows up at all.
The end result are dark photos with warm and cool shades of dark grey. After looking thru them I realized that the color is a distraction. The texture is so strong that it does not need color. Thus I ended up with a lot of black and white photos.
