Abstract
An approach is provided to generate a composite image of a moving object by using image stacking on a set of captured digital images of the moving subject. A composition depth-of-field of the moving subject is identified. A digital camera with a focus distance setting and an auto-focus system is used to capture the set of digital images with each of the digital images are at a different focus distance within the composition depth-of focus. Each of the digital images is focused using the digital camera's auto-focus system. The captured digital images are stored in a memory and the composite image is generated from the stored images by using an image stacking process on the set of images.
