The easiest, most effective way ---is to respond with a simple and direct "Thank You."

When faced with an award presentation, try approaching the Toastmaster (or presenter) to one side, accept the award on a side-by-side position so that you may comfortably face the audience, show the award with pride, and acknowledge a "Thank You."

If a camera(s) is present, face the camera and hold the "award acceptance" long enough for photographs to be taken. Avoid forcing photographers to "grab a shot." Most likely you will be caught in an awkward and often uncomplimentary position and/or facial expression.

This is part of the courtesy you extend to the audience, the presenting organization, and the person(s) taking the photograph. It is also a form of recognition you bestow upon the audience---a way of returning to them the recognition which they have given you.

You can do it. Pose with poise and face the camera.
