Normally, I am not into sunsets and sunrises, but every so often, when something like this stares me in the face, it is difficult to resist the temptation. What makes this are the lines and patterns. The touch or orange/red simply adds that little extra touch that caps the whole scene. You don't generally have much time to work a landscape like this because the light is changing so fact.
The trick is to be ready to take advantage of the "decisive moment."
You will see several more sunsets which are scattered through this book. They are all quite different.
