Moreover regardless of adopts what kind of existence the existent solution, digit imaging system's latitude must be a certain that cannot be intervened artificially value on the physical level after leaving factory. Some digital cameras are known as alterable latitude, but they change camera's latitude by past treatment through DSP. So users cannot change latitude, light-shade transition or color transition as film camera just by replacing film's type. Now the civil camera's minimum ISO is 50. This value is discommodity for users to photo by the long exposure or other similar mode.

The results showed that the stearates can accelerate the development of PTG material. The addition of NiSt2 greatly increased the maximum density and the sensitivity together with a slight fog increase. However the addition of BaSt2 and CaSt2 did not make such great increase in the maximum density and the sensitivity, together with a slight fog decrease.
