Optical latensification

The best point of attack for a determination of the surface electrochemical properties of latent images is at the level of latent sub-images. There can hardly be more than three sizes (2, 3,4) without gold sensitization, and only one size (N=2) with gold. Indeed, the continued presence of optical latensification effects after the application of optimal gold sensitization established the development threshold at N=3, not 2, in the presence of gold atoms. 

The return of optical latensification in the range from -170 to -210mv indicates that there is a less stable LSI which is being destroyed completely at potentials less negative than -170mv.
