that adsorb on the crystal surface. Therefore, sensitivity can be increased by adsorbing more sensitizing dye. This requires increasing the surface area of the crystal, and also improving the dye molecules to form a dense assembly. Tabular grain emulsion solves the first part of this problem.

Tabular crystals tend to lie along the film's surface when coated and dried. This reduces scattering of light and increases resolution.

Tabular crystals usually have two twinned planes parallel to each other.
