The analysis on the present status of photography has indicated that silver halide photographic systems are supported by the twin technologies based on silver halide microcrystals associated with outstanding performance of latent image centers as mesoscopic metal clusters and on organic functional compounds. Since those technologies are fine and highly composite, silver halide photographic systems are now, and will continue to predominate over other systems for taking a picture, making progresses in the future.
