AERIAL PHOTOGRAPHIC EXPERT REPORT 
by the AIRPHOT Expert System. 
I was requested to qualify the No. 90-029 Film. 
I can tell you the following: 
The Film was made by Mr.Kocsis from mixed agricultural area onto b&w Film 
with Em No. 33-077 at flight height 2420 m. 
The 5 km horizontal sight was estimated visually which is -rounded- 
2-fold of the flight height. 
The verbal description of atmospheric conditions and clouds type was 
hazy and cirrostratus respectively. 
The cloud cover was characterized with the octa number i.e. O/8. 
There was a proposition of the photographers for developing: no comment. 
The film was developed by Mr.Csordas on Versamat processor in DK-50 
solution at 24 C ,6 Min. 
After the developing the density range of the film was measured. 
Th har ristic valu ares 
control DO = O.14 test DO= 0.15 
Dmin= 0,41 
Dmax = 1.02 
&D = 0.61. 
log SE=0.4 
The value of control Gamma = 1.52 The value of test Gamma= 1.48. 
The 24 Din control Speed and 26 Din preliminary test Speed were compared. 
The description of the film acuity is:sharp. 
The edge function was not measured. 
The evaluation of No. 90-029 Film is : 
The No. 90-029 was exposed at 5 km horizontal sight 
and received hazy description about the atmospheric conditions. 
The visual acuity was described with the key word:sharp. 
  
The Mission No. 90-029 Film is probably very hazy because the atmospheric 
conditions decreased the LogE range onto 0.4 value. 
The Film is exposed correctly because the 0.27 value of Dmin is within 
the optimal 0.2-0.3 D range. 
The Film is slightly overdeveloped because the value of control Gamma has 
increased from 1.48 to 1.52 while the Speed has changed 
from 26 to 24. 
The density range of the Film with its 0.61 8D value is lower than the optimal 
according to the need of analog or digital processing. 
GENERAL QUALIFICATION:The Film is Unsuitable quality , 
because the horizontal sight is less than 3-times of the flight height, 
because the density range is lower than 0.8 6D, 
because the LogE range is lower than 0.6.
