Photographs have mood. Some have more mood than others. At times we can get so overwhelmed by what we see that we focus on the grand scenes only, totally forgetting about mood. Mood can be caused by mist, fog, and such. Sometimes that great mood is not all over the scene; you have to go find it. Let's look at an example:

Here is the basic scene we are looking at. It has a lot of mood already but that mood is not all over as it lacks in the foreground and in the sky. Now notice the fog rising from the water towards the horizon. Also notice the low clouds at the tree line. The trick is to notice these things while still at the scene. The scene can be so nice that we only want to capture the majestic scene without paying attention to what else we can find. Remember, that there may sometimes be photographs within the photograph that has a totally different mood than the rest of the photograph. Since you are already there and photographing, why not get as many different images as you can?

          Let's zoom in and go for that mood:

This image is taken a little while after the first. The sun is now out and bathing the mountain in warm light. I have zoomed in quite a bit. The fog rising from the water is now more pronounced. The fog or low clouds over the trees are more pronounced. The whole image is now more moody. It is a very different mood from the first image.

          When at a scene, look within the scene for additional images. Look for mood and attempt to capture it. Moody image can be very captivating to watch. Why not add some mood to your images?
