Focus Stacking with Photoshop and Elements
Focus stacking lets you extend the depth of field by combining multiple images, each each of the same scene, but with a different focus point. Photoshop and Elements each have their own way of combining the multiple images into a single photograph.
Shooting the Image
Each of the images needs to line up with the others. So the first step is to frame your shot using a tripod. Set the aperture to f-16 or the highest f-stop you can based on the light. Set your camera to manual focus. Switching to Live View may make focusing easier. Focus on a spot close to the camera. Take the shot. Then take multiple shots, each one focused on a point further in tot he subject. How man shots do you need? It depends on the subject. Try focusing on each separate plane in the field of view.
