While doing photography,one of the things that we need to keep in mind is that we have to capture the mood of the place/subject. It actually helps the viewer to get a better insight of what the photographer has witnessed and captured.
This picture was made in Manali, India. Although it was generally a very clear and bright day, there were several times when the sky would fill with clouds, sometimes so thick, that you felt that they would just explode into a heavy thunderstorm; there would be dark shadows of the clouds on the mountain slopes, giving the mountains a mysterious look; and then all of a sudden they would be gone, leaving behind a clear, sunny day.
Look for moments like this, it brings out the best in your pictures.
