division is based on the behavior for different times of development under standard conditions. Orthophotic emulsions given a family of characteristic or H. and D. curves, the straight line portion of which unambiguously defines a single tie-point. This tie-point may lie above, upon or below the axis of exposure and according to this a further sub-classification of orthophotic emulsions is defined. It is shown that all types of industrially used emulsions, including portrait emulsions, are producible conforming to the orthophotic type, but showing specific variations. The relation of these variations and anomalies to the distribution of sensitivity and latent image among the grains is discussed in the light of recent discoveries.
