IMAGE STRUCTURE
The following information was generated using the old
versions of these films. Granularity testing of old and new
films in several other developers suggests this information
should also be valid for the new versions.The data in this
section is based on development in KODAK HC-110
Developer (Dilution B), 68

Note:
Modulation Transfer Function and Spectral
Sensitivity were generated using the older version of this
film (KODAK TRI-X Pan Fim 5063). Preliminary data
suggests this information would be applicable to the new
TRI-X Films.
