Photo analysis
What, exactly, is photo analysis? Who performs an analysis? What methods are used? I'm sure I will think of more. Can any one help?

Must be able to detect slight variations in appearance of vegetation and contour and to identify geographical features and works of man in aerial photographs. May have the staff responsibility for the preparation of pertinent camouflage plans contributing to local security. Military experience desirable, Must have thorough knowledge of military installations, principles of identification, map reading and tactical employment or ground troops.

[[[photointerpretometer and various other optical instruments]]] Never did see any of these in our Photo Section in the SW Pacific. Our cameras were mounted in the tail of our low level B-25s and A-20s. When they started a bomb run the gunner would hit the switch and a 150 ft. roll of 9 inch film would take an exposure about every 3 - 4 seconds. After we developed the film our Section Chief would go thru the roll and mark the negs that showed the best bomb damage,-( in the case of parafrags did they land on aircraft - in the case of skip bombing, did they make a direct hit on a vessel) and those would be the one we printed. Then they would be delivered to 5th Bomber Command. Might be they had the fancy instuments over there to ANALYZE them. Jack Heyn, Photo Section 3rd Bomb. Gp., 5th A.F.

Jack asked me to add some photos that came from the 3rd's photo section as a reference... as you can see on the bottom of the photo, info is given to the photo interpreters such as Group mission number (3B-309) Location (Tadji) date/time (2-13-44-11:15) and the Sq/Grp (13S. 3BG) and a/c number (#715)

Back when I was a wee lad they taught us photo interpretation on lovely Bausch and Lomb light tables that were 40k a pop or so. Not sure what they used in the 40s. Now days it's all digital of course. Found a bargain on one on ebay, but I can't quite justify the shipping cost.

I think the photo interpreter/analyst officer would usually be assigned to a higher HQ than Group ... They were more concerned with pictures taken by photo-recon planes, not the combat shots. Their job was to look at pictures taken at oblique angles under the stereoscope, photointerpretometer, etc. Two pictures taken at slightly different angles of the same spot, under these instruments, appeared 3-D to the viewer, and his job was to pick out enemy installations, etc as mentioned in the MOS description above. Also had to be able to " see through " camouflage attempts of whatever the enemy was trying to conceal; troop concentrations, U-Boat pens, hidden factories--- again, as above. I think most of these photo personnel ( many WACS were used in this ) would have been assigned to Wing, Air Force, etc Headquarters, where targets would be identified by these methods, and then orders from that HQ sent to lower commands.

Photo analysis was used by the 8TH Air Force to determine the effectiveness of the bomb strike following completion of a mission. On our way back, after completing the mission of the day, we often would see two P-38 Aircraft headed toward the target area to take pictures of the damage etc. from a lower altitude.

Let me see if I have this right. 1. Different skills may be applied to photo/image analysis. 2. Two or more people looking at the same photograph may interpret it differently depending on what each person is looking for, ex. one is looking for casualties while another is looking for camouflaged vehicles/equipment. 3. Photo analysis is not limited to military use. Am I basically correct?

Two examples of "analyzed" photos provided to strategic or tactical planners at 14th Air Force Headquarters; Tien Ho Airfield, Canton, China and enemy installations at city of Yochow. Airfield photo was obviously taken by 9th Photo Reconnaissance Sq, China Unit. Yochow photo taken during bombing by 308th BG. Analysis performed at 9th PRS and HQ 14AF, markings done by Intelligence Section, HQ 14th AF. Both photos were used for future strike planning. That is all I know about either image.

Photo analysis is not limited to military use. 1. Sure 2. Not the best use of manpower, but sure. An example might be if something is being constructed in the target area. 3. Exactly right. Lots of civilian uses. Map making, resource management, law enforcement, and so on.

Looking at Tony's right hand photo above, I think the plane is flying SSW>NNE. I also see, beginning at image center and extending to 6 o'clock, a string of 6 bombs. There also seems to be, just above center. what appears to be a seventh bomb/bomb strike. For the rest, I would need military training. Close?

Photo reconnaissance was taking on a new dimension at RAF Medmenham, UK, staffed with both US and UK photographic experts. Scott Operation Crossbow

Mark, Does your information include when the 17th and 18th PIDs were assigned to their respective Air Force?

Thanks all for a lot of good information. The photos and video are all quite interesting. Scott, I gave you 5 stars for the light table. WOW! I have more questions, but they would be totally O.T. for this site. If any of you would be interested in continuing via PM, please let me know. Jim C.

There were several types of units involved with the processing of photographic reconnaissance in the AAF. Photographic Technical Squadrons (1-12). Assigned at various levels from group to command, usually to Reconnaissance Wings after the fall of 1943. Photographical Technical Units (originally called Photographic Laboratory Sections) (1-35 with gaps). Also assigned at various levels after fall of 1944, but more commonly to Reconnaissance Groups than the squadrons were. Photographic Laboratories (Bombardment Group, Very Heavy) (1-44). Assigned to B-29/B-32 groups. AAF Photographic Intelligence Detachments (1-20). Mostly assigned at air force level. First 8 activated in fall 1942. The 10th in fall 1944, remainder in 1943. I have no information on the 11th, 14th, or 15th. These numbers may have been skipped -- notice the late activation of the 10th. The 1st and 19th were assigned to the 325th Photographic Wing, rather than directly to Eighth AF. The 5th through 8th were assigned to First through Fourth Air Forces and were disbanded in 1944. The 12th was assigned to Tenth AF in the ZI but reassigned when it moved overseas. The 16th (probably assigned to the Third AF Photographic Unit Training Center) was at Will Rogers Field and was inactivated or disbanded in 1943
