Hallo,

I have aerial survey camera RMK A 15/23 (objective PLAEGON A 153). This
camera was used in special research project connecting with measuring
effects of the bidirectional reflectance from the uniform surfaces.
I need some information about optical properties of this objective,
especially about geometric effect influencing film exposure: exposure
fall-off and vignietting. This relationship for most cameras takes on the
form Ea=Eo*cos(a)^n. I should know n-value to correct scanned images using
this equation. I know that this value is estimating during cabriation
procedure, but I need the mean vealue.
>Could  you also point of the articles web sites where ca I find information
about this type of aerial camera?
