Two people Michael and an assistant would be working on the reports. The basic objective mensuration was made by microdensitometry at Itek, Some of the techniques employed using microdensitometry were edge slope gradient, acuteness, and power spectrum analysis. Unfortunately, the multilayer construction of color films introduces losses which lower the resolution of the color original and duplicate. This one yea nnn contract called for photography on Government furnished 70mm Film which consisted of a matrix of exposure conditions, two relative haze conditions, and two sun angles. An engineering model densitometer was modified to provide both Status A and narrow band filter densities, and the output made compatible with a standard teletype terminal for data display and input to a process control computer.
