Camera Technology: History and its Development


Camera Technology: History and its Development

If you like photography, maybe you use a camera every day. Whether it's to take pictures of everyday events, sights, or special moments such as weddings. However, did you know the development of the camera? The history of the camera can be traced further back than the introduction of photography. Cameras evolved from camera obscura, and continue to change through many generations of photographic technology, including daguerreotype, calotype, Dry Plates, films, and even digital cameras.

1. Camera Obscura
Camera obscura is the first camera in the history of photography. Obscura comes from Latin which means "dark room". This camera is shaped like a box with dark or impermeable space in it. The camera obscura can reflect light through two convex lenses, which then place the image on the film / paper at the focal point on the camera lens. The oldest record that addresses this principle is the description put forward by the philosopher Han Chinese Mozi (470 to 391 BC). Mozi confirmed that the camera obscura image was reversed because the light moved in a straight line from the source.

Alhazen - Camera Obscura

In the 11th century Arab physicist Ibn Al-Haytham (or also known by another name Alhazen) wrote very influential books on optics, including experiments with light through small holes in dark rooms. This camera was developed with the concept small holes in dark boxes that are illuminated by light can produce images. That was the starting point for all camera technology.

Before being popularized by Alhazen, in the era before Christ it was recorded that this concept had been discovered by a philosopher named Mozi in the era before Christ.

Joseph Nicphore Niépce was the first person to produce photographs using a camera in 1816. He produced his first photo using a very small camera of his own and using a piece of paper coated with silver chloride. Although at that time he could not produce a permanent photo, then in the mid-1820s, Niépce experimented again using a camera obscura focused on the tin plate 16.2 cm x 20.2 cm (6.4 in × 8.0) coated thin with judea asphalt, ie naturally formed light asphalt.

Camera obscura that is not practical has developed. In the 1660s, British scientist Robert Boyle and his assistant Robert Hook discovered a portable obscura camera. This camera is a form of modification of the camera obscura so that the shape is more compact.

Alhazen's book was also studied by western scientists like Joseph Kepler. This scientist finally managed to enlarge the projection of the image produced by the camera by adding a negative lens behind the positive lens. Boyle's robot then managed to make a small camera without cables in 1665.

the first camera that was very practical to use in the field of photography was invented by Johann Zahn, in 1685. The principle of this Zahn camera model was using additional slides as a tool to focus objects. The Zahn system is able to provide additional sensitive plates in front of the camera lens before taking pictures.

2. Kemera Daguerreotypes and Calotypes
Nearly 900 years after the discovery of the camera Obscura, in 1837 French Joseph Joseph Niepce discovered the concept of practical photography, which he later named as the Daguerreotypes and published in 1839. Daguerre used silver-plated copper sheets with iodine vapor to provide a light sensitive silver iodide layer . After exposure to the camera, the image was developed by mercury vapor and repaired with sodium chloride solution.

Camera Daguerreotypes

In a small box with a light hole, by adding copper and silver plates added to iodine vapor, this generation of cameras is more sensitive to light.

After exposure to the camera, the image is then formed through mercury vapor and sodium chloride solution. Niepce collaborated with his partner Louis Daguerre in the discovery of this camera, hence the name of the camera was named after the inventor.

Henry Fox Talbot perfected a different process namely calotype in 1840 and was commercialized. He developed a very simple camera consisting of two nesting boxes. The back box has a ground glass screen that can be removed and can enter and exit to adjust focus. After focusing, the ground glass is replaced with a light-proof handle containing sensitive plates or paper and a closed lens. Then the photographer opens the cover on the holder, opens the lens cap, and counts as many minutes as desired which is adjusted to the lighting conditions before replacing the lid and closing the seat. Despite this mechanical simplicity, high-quality achromatic lenses have become the standard.

3. Collidion Dry Plate
Collodion dry plate was used by people since 1857, this one camera was the work of Desire van Monckhoven. Fourteen years later, this dry plate camera was modified by Richard Leach Maddox who succeeded in creating wet plates whose quality and speed of shooting were better.

Colliidion's camera journey continued until in 1878 gelatin emulsion was found which was able to increase the sensitivity of the camera, so that the camera could take pictures spontaneously.

These are times when a tripod and other camera aids are not needed to take pictures. for the first time, the camera can be made quite small the weight is not too big to hold hands, or even hidden. There is a proliferation of various designs, from single reflexes and dual lenses to large cameras and handheld cameras.

4. Kodak and Film Cameras
Photographers born in the 90s must have known a camera that uses film rolls in it which can then be printed into a photo. Actually the film camera development had started a century before, namely since 1885 by George Eastman who started camera film production, which later developed again into celluloid in 1888-1889.

Kodak 1888 camera

Kodak 1910 camera

He named the film's camera as Kodak, which then began to be introduced to the wider community since 1888. More sophisticated than before, it only consisted of one focus lens and one shutter speed.

Until finally at the end of the 19th century Eastman had succeeded in making various film camera models, including box-shaped cameras and folding cameras. Although this Kodak camera succeeded in making photography not too expensive for many people, plate cameras were still widely used by people at that time because of the better quality. To compete with the camera roll, this era plate camera is equipped with a magazine to hold several plates at once.

5. Compact and Canon cameras
The history of the camera continued with the presence of a compact camera which was examined by Oskar Barnack at Leitz. Barnack uses 35 mm film to make a camera that can produce magnified images with very good quality. Finally, in 1913 the Ur-Leica prototype was formed, a 35 mm camera which was later delayed due to the first world war.

After several developmental features, the Ur-Leica camera went on sale widely in 1923. Since then, consumer camera users have been very satisfied and welcomed this one camera innovation.

35 mm Leica I camera, 1925

From here, then came the rival camera maker Ur-Leica, a Canon camera whose company was based in Japan. Canon also made cameras with 35 mm cine films, which then competed with Ur-Leica. Cameras made in the land of the rising sun later became very popular after the end of the Korean war which made many Japanese veterans bring these cameras to the United States. Of course, until now Canon continues to innovate to produce a variety of other sophisticated cameras, so that even now the business is still running fertile.

6. TLR and SLR
TLR stands for twin-lens reflex, while SLR is an acronym for single-lens reflexes. The TLR camera was started by Franke & Heidecke Rolleiflex in 1928, while SLR cameras as further developments began production since 1933, which first used 127 film rolls.

Contax S SLR camera

In particular, TLR cameras are equipped with two objective focal lenses of the same length. One lens is useful for the purpose of taking pictures, while the other lens is useful for capturing shadows that have entered the first lens. While on SLR cameras, there is only one lens that has been combined with a digital image sensor.

The SLR camera was popularized by the company Asahi Optical, which first launched a 35mm SLR camera called Asahiflex. In the 1950s, many SLR cameras were on the market, including Canon, Yashica, and Nikon.

1949 SLR cameras

While conventional cameras are becoming more sophisticated, a completely new type of camera appeared on the market in 1948. This is the Polaroid Model 95, the world's first instant-picture camera. Known as the Land Camera after its owner by Edwin Land. Model 95 uses a patented chemical process to produce positive prints that have been completed from negatives exposed in less than one minute. Land cameras are quite popular even though the prices are relatively high and the Polaroid range has expanded to dozens of models in the 1960s. The first Polaroid camera aimed at the popular market, the Model 20 Swinger of 1965, was a huge success and remains one of the best-selling cameras of all time.

The first camera that carries automatic exposure equipped with a light-meter selenium is the Super Kodak Six-20 pack in 1938, but the price is very high at around $ 225 at that time (equivalent to $ 3912 for now). In the 1960s, low-cost electronic components were commonplace and cameras equipped with light meters and automatic exposure systems became increasingly widespread.

MEC-16 SB 16mm subminiature camera

Subsequent technological advancements came in the 1960s, when Mec 16 SB German subminiature became the first camera to place a light meter behind the lens for more accurate measurements. However, measurements through lenses eventually became a more common feature found on SLRs than other types of cameras. The first SLR equipped with the TTL system was Topcon RE Super in 1962.

7. Analog camera
The history of subsequent photographic cameras arrived in 1981 when the manufacture of analog cameras began, which the shooting technique was still able to use celluloid film (cliché / negative film). The first time making this analog camera was Sony Mavica.

Sony Mavica camera

At the 1984 Olympics, the first time an analog camera produced by Canon was used to photograph the Yomiuri Shinbun, whose results were later published in Japanese newspapers.

But along the way, analog cameras are less enthusiastic about the community because the cost of their use is very expensive, and the image quality is not good when compared to other cameras. Analog camera applications are currently widely used for CCTV cameras.

8. Digital Cameras
The history of the development of digital cameras is inseparable from the development of video tape recorders (VTR), which is a technology of recording images on television. In 1951, for the first time, Bing Crosby Laboratory made an initial version of VTR. The tool serves to take pictures from a television camera, then convert the image into an electrical impulse (digital) and store it into magnetic tape.

Then in 1956, Charles P. Ginsburg and Ampex Corporation perfected VTR by launching the VR1000 version and commonly used by the television industry. So from there, between video cameras and digital cameras have similarities in the use of CCD (Charged Couple Device) to adjust the color and intensity of light. Since then, the era of digital cameras has started and developed rapidly.

"Separation" of digital cameras with video cameras occurred in 1981, where Sony introduced their first commercial electronic camera called Mavica. The workings of the first digital camera are images recorded onto a mini disc and then inserted into a video reader that is connected to a color monitor or television. Although Mavica cannot yet be called a digital camera, it is actually a modification of a video camera that takes photos spontaneously.

Meanwhile, since the mid-1970s, Kodak Company has had several discoveries about solid-state or clarity for image sensors, namely changing light to digital images for use at the professional and household consumer level.

Continued in 1986, Kodak for the first time in the world introduced megapixel sensors. This sensor is capable of recording 1.4 million pixels which can produce 5x7 inches of good quality digital print photos at that time. A year later (1987), Kodak also released seven (7) other products for recording, storing, manipulating, electronic transmission, as well as for printing images or objects. The digital camera was first developed by Fuji in 1988, which uses a 16MB memory card for save data taken photos. Furthermore, digital cameras began to be introduced to the wider community since 1989 by Fuji. In 1991, the marketing of a 1.3 megapixel resolution Kodak DCS-100 digital camera began.

The digital camera photo format began to switch to JPEG and MPEG which did not take much space on data storage. In 1995, digital cameras with liquid crystals on the back of the lens began to be developed by Hiroyuki Suetaka with the Casio QV-10 camera name.

Minolta RD-175

In 1995 Minolta introduced the RD-175, which was based on Minolta 500si, SLR with independent CCD splitters and three. This combination produces 1.75 million pixels.

DSLR cameras began to be discovered in 1999 beginning with the launch of Nikon D1 which managed to reduce production costs to just the price. This type of camera is capable of producing excellent images and high resolution.

Nikon D1 camera

Until now, DSLR cameras are still widely used by photographers with a variety of removable lenses. In addition, in general the price of DSLR cameras is not as expensive as it used to be.

Digital camera sales continue to grow, driven by rapid technological advancements. The digital camera market is segmented into various categories, Compact Still Digital Cameras, Bridge Cameras, Mirrorless Compacts and DSLRs.

Canon CMOS sensor

One of the most important advances in digital camera technology is the development of CMOS sensors, which help drive sensor production costs that are low enough to be able to be applied as cellphone or smartphone cameras.

Such is the development of photographic cameras from time to time. Hopefully this camera history adds to your knowledge in the world of photography.

RC (Remote Control) car Toys: History and Its Development


RC (Remote Control) car Toys: History and Its Development



Radio-controlled (or R / C) cars are models of electric-powered cars that can be controlled from a certain distance using special transmitters. The term "R / C" has been used in both "remote control" and "radio controlled", where "remote control" includes vehicles connected to their controller wirelessly, but the general use of "R / C" today usually refers to controlled vehicles by radio frequency link.

RC Cars are supported by various sources. The electric model is powered by a small but powerful electric motor and can be refilled with nickel-cadmium, nickel metal hydrides, or lithium cell polymers. There are also brushed or brushless electric motors. Most fuel-powered models use a glow plug engine, a small internal combustion engine driven by a special mixture of nitromethane, methanol and oil (in many cases a mixture of castor oil and synthetic oil), this is called a "nitro" car.

Recently, a large model has been introduced, powered by a small gasoline engine, similar to a motorized string trimmer, using a mixture of oil and gasoline. Electric cars are generally considered easier for beginners compared to model-based fuels, but can be the same at complex budget levels and higher skills.

RC cars are on-road and off-road. The Off-road model, which is built with full off-road suspension functions, and a wide choice of tires, can be used on various types of terrain. On-road RC cars, with far fewer suspensions limited to smooth paved surfaces. In the last decade, progress in "on the road" of vehicles has made their suppression adjusted to full scale.

History and  the development of RC cars
Many people certainly know RC Car or better known as a racing car remote control hobby toy. It turns out that the history of RC racing has begun from the beginning of the last century, by the clockwork organization in the 1920s and has been running on shows for special car races for a rotating toy car. In 1936 the Race Car Model was formed in England and filled with cars with rubber power sources like clockwork.

From the model it shows that 4WD rubber tires can speed up to 40 mph in less than 3 seconds. The weight of a car is usually 3 pounds, half of a rubber car. The cars will move and walk straight to the finish line.



Clockwork car race

In a few years, in America, a miniature gasoline engine was being put into the car, but a greater need for control was needed. Circuits with circular cable construction (tether) were built and with speeds reaching 60 mph in 1940. American car kits tend to be produced by companies such as Bros Dooling and Ohlsson & Rice.

In the late 1960s miniature solid cars using radio control systems were introduced. This model has been equipped with a servo-controlled steering, gas pedal (throttle) and brakes that can be controlled using radio control. The next few years, namely in 1966, commercially viable radio control cars (RC cars) were launched into the market. The car was produced by El-Gi (Elettronica Giocattoli), a company from Reggio Emilia, Italy. Their first RC Car model is 1:12 Ferrari 250LM. Then followed by the 1:10 model The Ferrari P4 was first shown publicly at the Milan Toy Fair in 1968. In the mid to late 1960, a British company called Mardave began commercially producing remote control car models (RC Car) . Their first product was a gas and nitro-powered model that was sold early 1970.

During this period several commercial RC Car products began to be produced by several small companies in America. Most of these companies started their business as slot car vendors and then changed direction as RC car sellers were increasingly popular at that time. The first kit produced is 1/8 scale nitro-powered aluminum flat pan cars that use a.21 engine or a smaller engine with a body made of polycarbonate.

In 1976, the Japanese company Tamiya launched a series of more detailed models using simple electrical mechanics. At a more expensive price, the Tamiya output kits that use this radio system sell quickly. Furthermore, Tamiya began producing RC car models that could be assembled with certain purposes, which were also the first models to use the original suspense system. With this system the RC car can be controlled virtually.


Meanwhile, in the United Kingdom, it shows its reliability in this case with the modeling skills of modelers and building cars. At present the cars from that era are hunted and used as collectibles for their enthusiasts or collectors. The emergence of the desire to race with several cars, coupled with the emergence of small engines, from 1 to 2.5cc, resulted in Track Rail and Rail Cars. The track consists of one rail section and the cars will sit on it, one car per rail.

Some cars from this period are arguably racing cars, the most elegant car models ever produced. Tether car racing continues to this day and they are the fastest model cars of all types. From a railroad car with an internal combustion engine, it will continue with an electric power car. Controlling a vehicle with radio control might have been in the mid-1950s but it wasn't perfect. Orders sent to vehicles only allow to turn completely in one direction or another, aka forward and backward. With radio units in the mid-60s available, they are able to provide proportional control. Precise precision steering input and speed control capabilities. Finally, after almost half a century of dreams, model car enthusiasts realized with the presence of fellow car model races.


RC racing itself began in the United States in the late 1960s. Precisely when it was still unclear. What is known is that in 1968 ROAR held a national championship in the United States. Although the first race meeting in the UK was held in 1971, it was another year before the BRCA was formed. The BRCA uses the ROAR regulation book as a guideline. In the US there was a proliferation of cars, in 1969/70 kit cars (assembled) were available. Some producers come from other regions of the world. Dinamyc models for example, come from slot cars, and some are new to hobbies. The number of cars available provides an exciting picture for the new sports produced. Kits come from such as Dynamic, Delta, Citizenship, Heathkit, Ra-Car, Associated, Kyosho, Mardave, PB, Thorp and the famous named Special Aluminum Reynolds.

The design of the car varies. Some are quite complicated and the engine is connected to an operational gearbox and has a basic suspension. Other simple chassis with Sidewinder engine configuration moves directly to the gear connected to the rear axle or on one of the rear wheels. Almost all have centrifugal grips. This becomes a ROAR requirement, but Dinamyc produces a car that has a torque converter with epicyclic gears operated by levers, to provide a boost. Over time, so that the engine produces more power, but more likely at the cost of manufacture, the chassis design is more towards Flat / Sidewinder (flat). In the mid-1970s the flat model became the highest design and was used until 1980.



In the mid to late 1970s the chassis design consisted of glass fiber. The main chassis is connected to a pod (aluminum) for pairing the engine and rear axle. A radio section is mounted on the chassis on the block, and also a 125cc fuel tank. The radio part can be mounted tightly to the chassis or secured with rubber grommets with screws for modification or adjustment. The gradual refinement begins with the ball bearing, disc brakes, plastic fuel tank, rear axle and adjustable exhaust. Used Flywheel / clutch with smaller units and PTFE. The evolution of this type of chassis was stopped in 1980 with the first introduction of the suspension of a new car. Until now the RC Car continues to develop with far more sophisticated technology. The scale also varies from a scale of 1:64 to a scale of 1: 5. (FL)

Combination of RC Cars with Artificial Intelligence
A team of British developers, found a wild idea: they tried to unite the concept of slot cars, radio control toys with artificial intelligence which is usually designed for video games. Finally they managed to combine everything in a set of revolutionary toys, named Real FX.

Real FX has the same passion as Anki Drive which was introduced months ago. The difference is that Real FX is easier for many people to enjoy because it doesn't need a handset or has to run on certain operating systems.

A set of Real FX consists of a toy car, a Smart Controller remote control, and a Smart Track circuit sheet that you can arrange as desired. Real FX toy cars utilize electro-optical sensors on the front and rear, they will communicate directly with the Smart Controller. With three 1.5 volt AAA batteries, the car can go for four hours non-stop.

Then for what artificial intelligence? Artificial intelligence will help you not to get off track when the car is speeding. If simulated in real size, these toy cars seem to drive at a speed of 180 mph - or about 290 kilometers per hour.


But this game still requires you to use skills to overtake your opponent, avoid dangerous things (such as puddles of oil until the tire erupts), repair the car in the pit stop, and become the fastest in the racing arena. If you drive the car too fast, it will slip on a sharp turn and get off the track.
And like a video game, you can play multiplayer or single player. You don't need other people to enjoy it. All you need to do is add another car and set it to Pace Car mode. The existence of artificial intelligence allows the car to race against you persistently.

The development team calls Real FX a toy that is easy to install and learn, but requires practice and flying hours so that it can be advanced. He will be equipped with a voice menu feature and also the announcement of competitions in eight languages (English, Spanish, French, Italian, German, Arabic, Japanese and Russian).

There are two modes that you can enjoy: Practice, where you can create the fastest time record, and your friends can participate in it; and the Championship, which allows players to compete together. You can choose the number of laps or customize the settings themselves.

Every time there is a danger ahead, the remote Smart Controller will alert the player. That way, you have to adjust your driving style before passing it. If it crashes, the performance of your car will drop temporarily.

Then there are also random events such as engine failure. If by chance your toy car is damaged, it will not be able to walk normally until you visit the pit stop.
