PHOTOMETRY FOR INTERPRETATION

A THREE-PART DISCUSSION OUTLINES THE POTENTIAL USES OF PHOTOMETRY TO THE PHOTOANALYST. THE FIRST PART CONCERNS THE USE OF A MICRODENSITOMETER AS A QUICK-RESPONSE AID FOR INTERPRETING FEATURES FOR WHICH GENERAL IDENTITIES ARE KNOWN, BUT FOR WHICH EXACT PROPERTIES CANNOT BE DETERMINED. THE SECOND PART CONCERNS THE PROCESS OF DETERMINING THE RESOLUTION OF AN AERIAL PHOTOGRAPHIC SYSTEM BY SUBJECTING HIGH-CONTRAST EDGES OCCURRING WITHIN AN IMAGED AREA TO FREQUENCY ANALYSIS. THE RESULTANT OUTPUT IS THE MODULATION TRANSFER FUNCTION WHICH EXPRESSES SYSTEM RESPONSE AS A FUNCTION OF FREQUENCY (CYCLES/MM). FINALLY, PHOTOMETRY IS APPLIED TO THE MAPPING OF OFFSHORE UNDERWATER AREAS. AN ACCOUNT OF AN EARLY RESEARCH EFFORT ACCOMPANIES A DESCRIPTION OF CURRENT AND FUTURE WORK. /AUTHOR/
