Emulsion Layer Of The Support Structure&
Emulsion layer of the support structure film base. Lightsensitive emulsions by fine particles suspended in a medium made of gelatin. The gelatin film used with certain foods like gelatin.
Suspended in gelatin with the photosensitive material is silver halide grains. Such particles so tiny, only be observed under high power microscope. Usually in one square inch of sensitive film emulsion, the
Silver halide crystal content of about 40 billion much!
Silver halide crystals with the structure upon exposure to changes in characteristics. The chemical properties of the mechanism of change is not an important for us, the end result of their change is the most important. How this change come about? When you shoot, the light shines through the camera lens on
The film emulsion layer, when the light reach the silver halide crystals, these crystals structural changes occur, and also by light irradiation with neighboring silver halide crystal coalescence each other up.
This type of silver halide crystals formed by coalescence of clumps is still very tiny. Emulsion layer receive the amount of light the more, the more crystal coalescence together, less

Resources like the one you mentioned here will be very useful to me! I will post a link to this page on my blog. I am sure my visitors will find that very useful.
