KODAK AEROCOLOR III Negative Film 2444 • AS-116 5
DIMENSIONAL STABILITY
The dimensional stability of aerial films is of particular
interest and importance in accurate mapping and in the
reproduction of maps.
Dimensional stability is an all-inclusive term. In
photography, it applies to size changes caused by changes in
humidity and in temperature, and by processing and aging.
The absence of solvent in ESTAR Base is one of the reasons
why ESTAR Base films show excellent dimensional stability.
The dimensional properties of ESTAR Base may vary slightly
in different directions within a sheet; the differences that may
exist, however, are not always between the length and width
directions.
