Abstract
It is pointed out that future progress in imaging technology for taking pictures will solely depend upon innovations in silver halide photography from now to the 21st century and will greatly benefit our cultural life. Analyses on the processes for image formation have revealed the existence of big room for future innovations in silver halide photography by conventional and unconventional ways. Extensive investigations of silver halide photography will contribute, not only to its progress, but also to the progress in the sciences and technologies underlying it.
