Recent speckle photography and application are reviewed. Topics include the laser speckle photography, whitelight speckle photography and electronic speckle photography. These recent applications involve the crack-tip deformation fields, the determination of surface strains and displacements, hybrid experimental method, large-object deformation, and the measurement of three-dimensional deformation fields. Image processing of a speckle pattern progressed quickly with rapid development of a computer and a CCD camera last decade. Therefore, it is expected that the applicable field of speckle photography spreads further.
