@@gregoryfilin8040 a most interesting and important question. When looking for things in the firld; there is a pattern to nature. When humans are trying to hide things, often they can get close to but quite mimic the natural patterns. That can sometimes be enough. In urban environments, the same breaking of urban patterns can also occur. Often it is this breaking of a pattern that makes one go "hmm" and. Own I have something to literally add figuratively focus on. This is why PIs spend a lot of time and effort learning the "normal" in order to learn the innocuous patterns, in order to recognize the illicit patterns....at least good PIs did. 👍 When I was a PI, it took about two years of formal training and about the same in OJT working with experienced PIs, before being allowed to work alone. It was a dull, tedious and boring job, on a good day. But for some of us, it was the best job. 👌
Note, contrary to this video most stereo was taken with one normal camera and one pass. One simply takes picture fast so that each photo overlapped the previous by more than 50%. This needed a calculation using ground speed, focal length of lens and height of aircraft above ground to determine the time between photos. Look at 27:03.
When I was in university, the Geography school has a class titled "Large Scale Low Altitude Aerial Photography." I took this class (and later I was a teaching assistant for the class). We built RC airplanes which were modified to hold a camera pod. We used 35mm photographic film to take aerial photographs. It was really fun to see the mosaics after the film had been developed. As you say, the overlapping sections of mosaics can be used as stereo photos. I took the class back in the '80s. We would remotely trigger the camera without being able to see if the framing was correct. We would just do our best to be over the target and then trigger the camera ever few seconds as we flew over the target. I was often presently surprised by how well the photos came out. This method of aerial photography was very clunky compared to modern drones but at the time I thought it was incredibly cool.
@@dickJohnsonpeter Did he? Here's my attempt at transcribing what was said. *"A lot of the photographs taken during the war were taken as stereo pairs. Either with a specially built aerial camera or, more often than not, the pilot would make two passes over the target making sure the photographs overlapped by at least 60%."* So either a *"special camera"* was used or *"more often than not, the pilot would make two passes over the target"* This is NOT the same as *"most stereo was taken with one normal camera and one pass."* Neither a *special camera* nor *two passes* were needed. The comment by Charles Phillips rightfully corrects the error in the original video.
My father was a Recon pilot in WW2 most the times that he took pictures that over lapped each other where and are the ones he took from high altitudes he did make two or more passes on his ground level photos because of some of the speeds he made the passes.
My late father was posted at RAF Medmenham as it was noted that his fine engineering skills made him ideal to maintain the miniature mechanisms in these stereoscopic cameras. Of course, he wasn't able to talk about it until 1998 or thereabouts.
Thank you for your great channel, specially this episode! My father was at the Luftbildstelle during the war so it was interesting but also a bit disappointing because I did not learn anything about the german side.
Another book you might like to check out on the Recon pilots of WW2 is called " Eyes of the Eighth" a story of The 7th photographic Reconnaissance Group 1942-1945. There alot of there missions that the pilots flew and some of those the where shot down along with the photos they came back with and where are in the photos. My father was one of those pilots and one of the most highly decorated recon pilots in the 8th Air Force 7th photo group
An interesting use of photo interpretation in peacetime prevented all-out war in 1962. In what became known as the Cuban Missile Crisis, Khrushchev moved nuclear missiles with Russian crews to Cuba, and was delivering more. While the Soviets claimed that no Russian troops were stationed in Cuba, only Cubans, our reconnaissance flights revealed that in the barracks area of the newly built base, there were soccer (football) fields, not baseball diamonds. Since Cubans prefer baseball (Fidel Castro himself once tried out and was rejected by the Yankees) rather than soccer, these photos were used to prove to the UN that the Soviets were lying, and there were Russian troops in Cuba. Because of the pressure of world opinion, and the US “quarantine” (blockade) of Soviet ships approaching Cuba, Khrushchev backed down and removed the missiles.
You must have learned your history prior to the declassification of the Cuban missile crisis documents. Khrushchev agreed to remove the missiles only after JFK's brother delivered agreement that we (the US) would remove the nukes from Turkey in exchange for the removal of the missiles in Cuba. In this respect Russia won the stand off. As the whole reason for moving Russian nukes into Cuba was because JFK pushed NATO to allow nukes to be moved into Turkey. JFK let himself be pushed by the war hawks in his cabinet to put nukes in Turkey. Inspite of his own fears that it would cause escalations by Russia. During one of the meetings during the Cuban missle crisis JFK asked, "do you think Khrushchev did this in response to Turkey?" Everyone the war hawks in his cabinet said yes, without a doubt.
@@williamallen7836I did hear that at one point, and no doubt JFK and LSK did work out a compromise. However, LSK did expect that his public denial of the stationing of Russian soldiers would lead the world to conclude that the missiles were “sold” (or given) to Cuba and that only a few “advisors” came and spent a weekend training Cuban soldiers, then went home and left Cubans in charge. But the photos proved that enough Russians had planned to stay long enough to build a soccer field on a base that housed no Cubans, so a baseball field would not be needed. LSK was more willing to pull back once the intention to stay long term, and control the missiles themselves, was shown to the world.
I live not far away from Gretna in Southern Scotland which had, and and still has, an ammunition storage area, so I spotted the munitions depot straight away.
Makes me think of the post “wildfire” drone footage of Santa Rosa, Paradise CA, and now of Lahaina on Maui. Anomalies they have in common require interpretation.
Hello !!! #FavoriteEpisode by far, #ThankYou I scored\ identified, four correct photo recon prints. Without training, I am happy with my 30.1% score out of 100%.
Whilst I get that the "aircraft id" segment (17:38 onward) could be fun, I'm not sure what proportion of people watching this video could identify specific WW2 aircraft models even when given 4 or 5 high quality photographs from multiple angle, rendering the any discussion of the difficulty of doing so from an aerial photo rather academic.
That old film at the end has me wanting a feature length dramatization of aerial reconnaissance and photo interpretation
If you're interested in reading more on the subject, the book "Spies in the Sky" by Taylor Downing covers it well
As an old PI, I appreciated the history.
And you are most correct, PIs are looking for just something that does not look right
If I may ask, what makes something look "not right" or "unnatural"?

@@dickJohnsonpeter No, he said the pilot made 2 passes to get the overlap. It was all done in one pass.

10:12 Brutal commentary
Great video, Gilles...👍

Great video! An unrelated question: what’s that mellow banger of an intro music you use?

Marchetti needs a k sound, 'Marketti'.

I spotted the Italian Savoia-Marchetti planes, and I'm no great expert.
Oh, wow, my guess was right, it's "Medmenham"!
I could do the guessing game of aerial pictures all day long.
I got the ammo dump and the water tower
You shouldn't use particle board for shelves. They're sagging.
The middle one is propably rattan, not particle board.
The one officer in the War interpetation training film looks like Alan Ladd. ?
It is
The only thing I was able to guess was the ammunition depot 😊
I could identify the defensive line of dragon's teeth because of the war in Ukraine. 😬
“Farmers in this area spread their hay”
Geoguessers could run circles around them I bet
But not during Operation Market-Garden.....
As a pro geoguesser these people dont have shit on me.
I guessed dachau - been there and felt terror pulse the instant I realized its what I'm thinking, just before you confirmed my grave suspicion
