When preparing to photograph mountains, the first things a photographer checks are the weather forecast and where the sun will be rising and setting. These days there are phone apps that help inform photographers on both of these items.
The easy question to answer is where the sun will be rising and setting. These apps track the sun accurately throughout its journey across the sky no matter where you are in the world. The hard question to answer is the weather. Weather apps are not as accurate especially when mountains are involved. Mountains shape the weather and climate around them leading to complex and interesting weather patterns. They alter local wind patterns, deflecting the winds in different directions, sheltering some areas from winds, and enhancing winds in others.
The morning I took this photo was a prime example. All signs pointed to a clear day when we left the hotel. Twenty minutes or so later, we were standing on the beach looking at nothing but clouds and fog. For the next two hours, the mountains played hide and seek with us. We would get a peek at the mountain peaks for a minute or so and then they were gone. Most of the time they peeked through, the peaks were not clear. This game went on for the rest of our time there. This photo was one of the times when the peaks could be seen without any clouds to hid their details.
