17 February 1967 MFMORANIJtM FOR; Director, National Photographic Interpretation Center Photo Analysis of UFO Photography- 1. This memorandum is in response to Project Number 66120-7, submitted by requesting that perform a photo analysis of-photographs imaging an... alleged UFO (i.e. -unidentified.flyih --abject).---T 2. The photography for this project-was-,supplied by the Aerial. Phenomena Office of FTD-(TDET/UFO); located at Wright-Patterson AFB,-. Dayton, Ohio. The photographic package-included three photo enlarge Slinger havtug- an -approximate 2"x3'._image.format. - These-original-= prints were not available for the-pb to-analysi This letter single factor greatly hampered-- he t ysis and prevented any hopes of esteablishing meaningful--answers:= _ this factor..

These-four enlarged-photograph.s.ver.e, copies reproduced from a second generation negative and attachments approximately the same-time-and from approximately- the sane-camera station as were the-UFO;.-photographs. -The_image.::quality-of these - four prints were less than optimum_and:were-considered poor for of a helicopter (attachment 4). -The-latter-was supposedly taken at--- -- ments of the UFO (attachments 1,=2 and:3)-and one-photo enlareenent _ 3. Also included in the photographic. package. were five photo- graphs of the alleged exposure station-and surrounding vicinity. These photographs (attachment 5) were-taken--with-a Polaroid Swinger by Major R.W, Nyls of the USAF Re personall investigated the UFO exposure station on the shore-of-Lake St.:Clair, Michigan, and tried to duplicate as closely as-possible the exact position of the original carrera exposure stations: -Major Idyls also provided exact measurements of the area and objects imaged in the original UFO Approve for Release ,lo 000015433 SUBJECT: Photo Analysis of UFO Photography photographs (attachments 6, 7 and 8). These photographs along with the measurement sketches and investigation report provided a means of obtaining an approximate photographic scale. This scale value was then used to obtain approximate dimensions of the VFQ. However, to do this the photo-analyst had to first make major assumptions. These ass.w ptions were necessary in a photo analysis-of this type where.. insufficient data is available or in doubt. If any of these assumptions are-in error the obtained -- dimensions are likewise in-error........ -== -:-:- 4, The assumptions used in-this-photo analysis.are as follows: a. UFO uas"t a distahee . 5-miles from camera station when photographed- (this information supplied by Major.Nyls in his-investigation report ). b. The measurements-supplied by Major Hyls.are, c. Photographs-shown in attachment 1 and 2 are full ` format, e. The distance:-between--the=cami;ra station and the object was large enough to that adjustments to the camera focal lenSth need not--be.considered. 5. ALtachment 9 represents &,.. - artists rough conception of the UFO along with the averaged-dimension obtained from the mensural analysis of the photograph shown-in attachments 1 and 2. Again, the user of this-information-must becautioned that the dimensions shown here are only approximations-based on assumptions. The quality of the photography,-the crude estimation of the distance from the camera station_to_the-fojoct--theJ.ack of original prints and precise camera data all-.tend: to.invalidate the answers. A good example of how the dimensions could change is illustrated by any change in the distance of the object from the camera station. The dimensions will change in direct proportion as the ratio of any new distance divided by the 0.25 mile distance that was used, i.e. 0.20 mile -; 0.2 - 0.0.0; therefore, cauc!n; the new values to be 80% of the original values. _ d.
