Aerial Photography RAF Style
« on: March 13, 2011, 01:23:59 PM »
19 years ago I left the RAF after serving 12 years in the photographic trade.

I thought that you my fellow forumeers may be interested in these pictures of cameras and the images they took.





This is a Zeiss RMK camera used for aerial survey.It takes/took 9inch wide images on 500/1000ft lengths of film

The `standard camera fit` for the PR9 Canberra was.

3x F95 70mm 100ft capacity cameras in the nose, one pointing directly ahead and the other 2 point obliquely left and right.

2 pairs of `split pair` F96 cameras in the fuselage with a focal length of up to 48 inch.
The F96 could hold up to 1000ft of 9inch film, but 500ft was the `norm`.

Images would overlap, by 10% between adjacent images, 60% fore and aft, and 30% Lateral, so nothing was missed.

Any consecutive pair of photographs could be viewed stereoscopically

Between these pairs are 2 vertical cameras V1 and V2, V1 was normally a Zeiss camera which used either a 6 inch of 12 inch lens, while the V2, an F96 camera, had up to a 48 inch lens.

The Zeiss had a magazine that held up to 500ft of 9inch wide film.

Another camera (system III) that was used in the V1 bay, was derived from the Hycon B that was used on the U2 spyplane, which had an articulated `pointing` mirror lens, and had a 36 inch lens, and used two magazines of 1000ft, and would sweep from horizon to horizon and from around 50,000ft could look hundreds of miles in to `enemy` territory, each negative was 9x18 inches in size.This camera was so good , you could fly over the Isle of Wight at 30,000ft and take a picture of Big Ben in London.

Other cameras include Texas Instruments ARI 5969/3 Infra Red linescan, which is used for detecting `hotspots`

Believe it or not, the usual film speed that was used was a very low 25 or 50 ASA.

This could be used because the larger cameras had IMC (Image movement compensation) fitted to them.

This moved the film slightly during exposure so that the image stays in the same place on the negative, also due to the height that survey images were taken from, there is no danger of image movement.



This picture shows the 70mm film using F95 camera, at the front is the camera with a 12inch Taylor Hobson lens, the right hand side shows a 100ft 70mm film magazine, and on the left is a complete assembly with a 3inch Taylor Hobson lens

This shows the coverage given by 4 F96 cameras as used on the Canberra PR9.


This is an oblique image of York Minster taken with an F96 camera


This is York Minster taken from around 30,000ft using an F96 survey camera.
The focal length of the lens used would be a 48inch

This is an enlargement of York minster from the image in York-2


This is a full frame image taken with the F95 camera on either the port or starboard side of the PR9 Canberra


This is taken using a Texas Instruments ARI 5969/3 Infra Red linescan camera.
Note the funnel show up as hot spots


I believe that some of these images exceed the limits for posting pictures, but seeing as though this would be a `one off` ,I hope that I can excused this time

Thanks for looking.

Interesting information Gordon. Considering the changes we've seen in our 'normal' cameras I wonder what the cameras used these days look like and also what the lenses are capable of?

Thanks for sharing this.

Thanks guys.

At the moment with the advent of digital etc, the RAF uses the Raptor pod on the Tornado.

http://www.raf.mod.uk/equipment/raptor.cfm

It is used in `real time` so what the aircraft takes, an operator many miles away can see what is going on and take the appropriate action......

Its all clever stuff..........
