Dan Gibson Parabolic Microphone

1072MarPMShown here is Canadian wildlife photographer Dan Gibson using the parabolic microphone he developed. Here, he has the mike mounted on the prow of his canoe, which allows him to silently paddle up in search of wildlife.

This photo is from the March 1972 issue of Popular Mechanics, in which he is described as a photographer who developed the tool primarily to capture photographs of wildlife. The article hinted, however, that the system could be used to capture wildlife sounds on tape. Thanks to this microphone, Gibson became more famous as a recording artist, with his Solitudes series of recordings of nature sounds and music. Here, for example, is his recording of La Mer (Beyond the Sea):

You can find the label’s recordings on Amazon, or find more information at their facebook page. If you’re looking for a parabolic microphone, here are some of the current offerings:

Fotomat: 1971

1971Jul16LifeFifty years ago today, the July 16 1971 issue of Life magazine carried this ad showing one of the most iconic structures of the 1970s, namely, the Fotomat.  According to the ad, there were 1000 such structures in parking lots coast to coast.

The first one appeared in California in 1965, the company went public in 1971, was listed on the New York Stock Exchange in 1977, and peaked at over 4000 Fotomats in about 1980.

For our readers who are too young to remember, there was a time when photography required a commodity called “film” that went inside the camera. When the film was exposed to light, a latent image would form on the film. When the film was used up, it had to be removed from the camera in complete darkness, and taken somewhere to be “developed”. This process would turn the film into a “negative,” with a visible image but with the colors reversed. The negative would then essentially be photographed a second time, and turned into a “print.”

A whole industry developed around this process. Stores sold film, and many of them allowed you to drop off the film to be developed. Typically, the film was sent by the store to a distant laboratory, and you came back a few days later to pick up your prints. It wasn’t until the end of this agonizing wait that you found out whether your pictures turned out OK.  You typically paid for the developing when you picked up the pictures.  They would charge you to develop the roll of film, but if some of the pictures were hopeless, they wouldn’t bother making prints of those, and you would only have to pay for the ones that they printed.

There were two solutions to this agonizing delay. The first was the development of the Polaroid camera, sometimes called the Land camera in honor of its inventor, Edwin Land.  (As a youngster, I mistakenly assumed that Land cameras were for use on land, and other instant cameras were better suited for use on the water.)  These cameras, through a seemingly magical process, allowed you to get the finished picture after a wait of only a minute or two.  We previously featured one of their early models.  The Polaroid cameras and their film were, however, expensive, and the image quality was not as good as even an inexpensive traditional camera.

American business, therefore, came to the rescue, and speeded up the developing process as much as possible. The film still needed to be sent to a large lab for developing, but Fotomat was a pioneer in expediting this process as much as possible: You dropped off the film at their little building in the parking lot, without having to get out of your car. The film was sent to their lab the same day, developed overnight, and you could pick it up the very next day, again, without having to get out of your car. You could also buy film from them, as well as other photographic accessories such as flash cubes, and even low-end cameras.

The first existential threat to Fotomat came in the 1980s with the introduction of the minilab.  A minilab was a self-contained photo processing system that was small enough to put inside a retail store. No longer was it necessary to send film to a distant lab. The whole process could be done right in the store by someone with only minimal training, and it could be done while the customer waited. Fotomat allowed you to do the whole transaction without getting out of your car, but you still had to come back the next day. With the minilab, you would have to walk into the store, but you could get your pictures minutes later. Even though Fotomat “put girls in our stores who really enjoy smiling,” the chain could not compete with the faster service now offered inside a traditional store.

Of course, the final death blow to Fotomat was the digital camera, which no longer requires film or developing.

Since there were thousands of these Fotomats in supermarket parking lots around the country, many are still standing. Many of them were converted to drive-through coffee shops, although other businesses have adopted these small structures. You can see many examples at this Flickr group.  You can probably see examples right in your neighborhood. Look in the parking lot of your closest strip mall, and you’ll probably find one.



1943 Opaque Projector

1943SepPSDuring my school days in the 1960s and 1970s, the teacher would occasionally wheel out a monstrosity known as the opaque projector. It would project the image of an opaque object, such as the page of a book, onto a screen. Apparently, the models of that era had about a 1000 watt lamp inside, and their size was due in part to the fact that they required a big fan to keep it cool. The process also required a lens that was quite large.

The projector was rarely used. Instead, it was much more common to copy the desired image onto a transparency, which was projected with the much more common overhead projector.

75 years ago this month, the September 1943 issue of Popular Science showed how to make an opaque projector. The article doesn’t seem to specify the wattage of the bulbs, but since ordinary household bulbs are shown, I assume that they would be 100 watts. The lens is made from one, or preferably two, magnifying glasses mounted in a tube.

The opaque projector has been more or less replaced by the document camera, such as the one shown here on Amazon, which can be viewed through the video projector that is now found in almost all American classrooms.

W9ZYB, Norwood Park, IL, 1938

1938JuneRadioNewsShown here on the cover of the June 1938 issue of Radio News is the well equipped station of Bert Heuvelman, W9ZYB, of Norwood Park, IL, a suburb of Chicago. The attractive homebrew transmitter, mounted on a panel of blue linoleum, consisted of a 6F6 crystal oscillator, T20 and T55 buffers, with two T200’s in the final running a kilowatt. The crystal mike was fed to a pair of 2A3’s driving a pair of 822’s in the modulator. Band switching enabled fast band changes. A Hallicrafters receiver was used, and the output was constantly monitored with an oscillograph and modulation meter.

Assisting Mr. Heuvelman is Miss Naomi Anderson, a professional model borrowed from the magazine’s sister publication, Popular Photography.

The magazine notes that the photo was captured with the help of over 3000 watts of flood lights illuminating the scene, and was the work of Henry F. Kroeger, Jr., of Chicago, who used a Kodak Retina II.



Making Movies in a Volcano, 1933

Screen Shot 2018-04-20 at 11.14.30 AMEighty-five years ago, the cover of the April 1933 issue of Popular Science shows cameraman Arpad Kirner being lowered by a fireproof rope 800 feet into the mouth of an active volcano in Italy. He explained that while his colleagues contented themselves on looking down into the volcano, he was able to view phenomena unseen by any human before.

Accompanied by friends (selected for strength to work the winches), he went down and studied the walls with an electric light powered by a wire running alongside the rope.

Of course, it is quite apparent that this stunt was dangerous and should never be repeated. This, of course, is because both the rope and parts of Kirner’s suit were made of deadly asbestos.

Despite the danger posed by the asbestos, Kirner was lucky and lived to the ripe old age of 78, as documented by his grave in Slovakia.



Air King A-410 Radio-Camera

1947DecRadioRetailingIn 1947, Santa undoubtedly received many requests for one of these little beauties. It was obviously an idea before its time, but Air King obviously anticipated the cell phone camera. With the available technology of the day, they produced this combination camera-radio, the model A410, shown here in the December 1947 issue of Radio Retailing.

The camera featured a 50 mm lens, and could take either black and white or color pictures on standard 828 film.

The four tube radio ran on one flashlight battery and a 67-1/2 volt B battery.



OSS Collecting Tourist Photos, 1942

1942Oct5Life1Seventy-five years ago today, the October 5, 1942, issue of Life magazine included this nondescript tourist photo as an example of something the government desperately needed.  Specifically, the Office of Strategic Services (OSS), the forerunner of the CIA, was requesting tourist photos from around the world for use in invasion planning.

1942Oct5Life2To illustrate the point, they provided this map of hypothetical Fitzhugh Island, the site of a powerful radio transmitter being used by the enemy.  To silence the radio station, an invasion was required.  The location of the radio station was clearly visible on the prewar map.  But many details necessary to mount the invasion were unknown.  In particular, it was not known whether the beach was suitable for landing the invading forces.

This is where prewar tourists got involved.  In a dusty photograph album somewhere in America, there probably existed photographs taken during a prewar vacation to Fitzhugh Island.  That photograph, shown above, needed to get into the hands of the OSS to confirm that the beach was suitable.

Many photographs would be useful for things like determining the composition of roads (and whether they would support a tank) and their width.  The photo shown below could be used to measure the width of the roadway, since the tourist’s height was known or could be readily estimated.  The image of the ship in the background also provided valuable clues as to the harbor’s suitability for invasion.

1942Oct5Life3

To get these photographs where they were needed, the OSS was asking for “all photgraphs (stills and movies) taken by tourists outside the U.S., in Europe, Asia, the Philippines, South Seas, Africa.  All types are useful, even family groups.”  To facilitate handling, the magazine asked those in possession of such photos to write for a questionaire (but to complete the questionaires before sending any photos).  The magazine provided the address of the OSS as P.O. Box 46, Station G, New York, N.Y.

After the hypothetical case of Fitzhugh Island, the magazine turned to an actual example of where such photos had been used. On February 27, 1942, British commandos under the command of  Lord Louis Mountbatten launched  Operation Biting, a successful raid against a Nazi RADAR at Bruneval, France, about twelve miles from Le Havre.

The BBC had previously broadcast a plea asking all people who had spent a holiday along the northern coast of France to send in any pictures they might have taken. Among the pictures that flooded in were the two shown below.

These  photos showed some critical details necessary for planning the raid.  The photo of fishermen on the left showed that there were cars on the beach, thus confirming that the sand would support mechanized equipment.  And the landscape on the right revealed a fence and the exact location of the road to the station.



Alien Surrender of Shortwave Radios, Cameras, Guns, 1942

1942janradioretailing

 

Shown here, in the January 1942 issue of Radio Retailing magazine, are resident aliens in Los Angeles lining up at a police station to turn in their cameras, guns, and radios capable of receiving short wave.

The magazine noted that Attorney General Francis Biddle had issued an order that enemy aliens, that is, citizens of Japan, Germany, and Italy, turn these items in to the nearest police station.  An alternative would be to have receiver rendered incapable of receiving signals other than those in the standard broadcast band.  Therefore, the order “seems to open the way for radio servicemen to render a useful service of eliminating shortwave reception from aliens’ sets–and get paid for it.  In this way, the alien may keep his set for regular broadcast listening to U.S. stations, while the police authorities are spared the storage of hundereds of radio sets which they are poorly equipped to handle.  And the radio man collects $1 to $2 per radio set altered.

Typically, the modification consisted of removing the shortwave coils, and providing the set’s owner with an affidavit documenting the modification.

75 years ago today, the Chicago Tribune, January 6, 1942, carried an article regarding the status of the order.  It reported that local officials found the response so far to be unsatisfactory, since fewer than 2550 cameras, guns, and radios had been surrendered as of the previous night, despite an alien enemy population of more than 50,000 (28,000 Germans, 21,000 Italians, and 250 Japanese).

The Chicago police reported that the items surrendered included several antiques, including an 1878 breach loader. One man was reported to have “embarrassedly handing over a sawed off shotgun, possession of which had been taboo in Chicago ever since the prohibition gang war era. He said that he inherited the weapon from his father.”

One man, not bothering to wait for a receipt, simply drove up to the police station, hurried a radio from his car, and drove away. Another motorist tossed a $100 radio from his car and drove off.

The paper also reported a supplemental order from the Attorney General listing the following prohibited items:

Weapons or implements of war or component parts thereof; ammunition of all kinds; bombs; explosives or material used in the manufacture of explosives; signal devices; codes or ciphers: papers, documents, or books In which there may be invisible writing; photographs, sketches, pictures, drawings, maps, or graphical representation of any military or naval installations or equipment of any army, ammunitions, implements of. device or thing used or intended to be used in the combat equipment of the land or naval forces of the United States or of any military or naval post, camp, or station.

 



Polaroid Swinger Camera, 1965

PolaroidSwingerShown here in the Winter 1966 issue of Elementary Electronics is the Polaroid Swinger camera, which came out in 1965.

Priced at just under $20, the camera was enormously popular. The black and white images developed automatically outside the camera. After snapping the image, the film was removed, and the user had to wait about a minute while it developed. After it did, the film was pulled apart, revealing the image, which then had to be fixed by coating it with a varnish-like compound that came with the film.

The red shutter button could be squeezed, and the camera would indicate “yes” or “no” as to whether the exposure was set correctly.  It accomplished this feat by means of the ingenious mechanism shown below.  Turning the knob adjust the aperture, and by squeezing the knob, it compared the amount of light entering the camera to the light produced by an internal bulb.  When the setting was correct, the internal light caused the word “yes” to appear through the viewfinder.

Not surprisingly, the film is unobtanium today.  However, according to some reports, if you find a roll of the old film tucked away, it will probably still produce a surprisingly good image.
