To a fairly large extent, photography is about being in the right place at the right time. Look through a magazine like Arizona Highways and notice each wonderful photograph. Had the photographer not been there at that moment in time, those photographs would not have happened.
It's the same with your photography. Rarely do great photographs come knocking on your door. You have to seek them out. You have to travel to where the great photographs are. You have to be there at the same time of the day that the great photograph is.
Great photographs are elusive things. You have to hunt them out.
Being in the right place at the right time is not enough, however. You can be in the right place at the right time and completely miss the great photograph. If you are not actively looking for the great photograph with a camera ready, you will not find it. You have to look critically all around. You must be prepared to capture it!
That is still not enough to capture the great photograph. You have to choose wisely what equipment and settings you will use. You will have to choose wisely composition. You have to choose wisely how you want the photograph to look and what you want it to say. One wrong move could be the difference between a good photograph and a great photograph.
Don't let the great photograph get away!
