Dears,

You could use a servo to press the shutter release button.

Easy - place the Arduino on a table or other suitable surface. Grab your camera and take a photo of the Arduino. Post the photo here so we can all admire the beauty of your creation.

(We are going to need much more information about what you are trying to do before we can answer the question.)
