A Brief History of Camera
Photographs are important for many reasons. For example, pictures are an indication of the things you value because you would only take photos of significant items, people, or events. Pictures are also useful because they help you store memories that you can share with future generations. In some cases, photographs inspire revolutions in politics or society. Today, the photography industry is worth $82.6 billion and it is growing at an annual rate of 5.9%. The global success of this market is astonishing given its humble beginnings. Here is a brief history of camera.
– The Camera Obscura in Ancient Times
Today, people use cameras from renowned brands such as Nikon, Canon, Sony, and Kodak. The technology used to make them originated from an ancient device known as a camera obscura. It projected the image of an object onto a screen. During the sixth century, a Greek architect in the Byzantine Empire used the camera obscura to conduct his experiments.
His name was Anthemius. In 1000 AD, an Arab known as Alhazen Ibn Al-Haytham invented the pinhole camera. Then in 1685, Johann Zahn envisioned the small portable camera but the invention of this device did not happen during his lifetime. Instead, it occurred during the 1800s.
– The Box Camera in the Late 1800s
John Herschel, a British scientist, was the first person to use the term ‘photography.’ He came up with it in 1839. In the late 1830s, another Briton known as Henry Talbot invented the first negative upon which a person could make a number of positive prints. However, it was George Eastman, an American, who developed the first box camera. He called it a ‘Kodak.’ He started selling his box camera in 1888. The Kodak used a photographic film to capture pictures. The lens focus was not flexible and it had a single shutter speed.
– The Reflex Cameras in the 1920s
One of the biggest problems with the Kodak was that you could only see the object you wanted to photograph through a viewfinder. That means your view was different from that of the lens. To address this problem, innovators developed a Single Lens Reflex (SLR) Camera. The successful design for such a camera occurred in 1861 even though the idea for it had existed since 1676. In 1884, the first SLR cameras went into production.
Unfortunately, the complexities of these cameras were too much for those who wanted them. By the 1920s, innovators had reduced these complications drastically and as such, the SLR cameras became widely popular among professional photographers.
– Digital Cameras in Contemporary Society
Instant cameras were popular before the digital revolution started. Edwin H. Land invented these cameras and the sale of the first one took place in 1948. It is important to note that the top selling camera model of all time was the Model 20 Swinger developed in 1965. It was an instant camera. However, digital cameras changed the world of photography entirely.
Today, all you need is a camera and a storage device. Paper, film, and ink are no longer necessary. The technology for digital cameras dates as far back as the 1960s when NASA started sending digital images back to earth from its space probes. Kodak launched the first Digital SLR camera aimed at the mass market in 1991. Today, digital cameras are the norm.

You may not realize it, but the way you view things is critical to your survival. More specifically, humans and many other organisms see things in 3D. This kind of visual perception allows you to sense danger so that you can calculate a route of escape instantaneously. For example, you can judge how close a car is and then jump out of the way. It sounds like a simple process, but it is highly complex. Experts in visual technology are now making it possible for you to view electronic images in 3D. The question is how they are doing it. In other words, how does 3D technology work?
– The Principle behind It
You have to understand how the human eye works before you can appreciate how 3D technology operates. First, humans have two eyes with a space between them. That is an important point to remember. Each eye captures a slightly different view of a person’s surroundings. Then the brain creates depth as it generates one image from these two views. Stereoscopic vision is the name scientists use to refer to this phenomenon. Similarly, 3D technology produces two distinct images.
Then it sends one image to one eye and the other image to the other eye. That means your eyes are capturing two different images from the electronic source and therefore, your brain creates depth as it processes these images.
– The Principle in Action: Anaglyph Glasses
Anaglyph glasses transmit light in a unique way. Each one of them comes with two lenses. One is red while the other one is cyan. The red lens allows red light to pass through it while the cyan lens allows any color to pass through it except red. That means your eyes would see different images since one lens rests on one eye while the other lens rests on the other eye. Your brain would create depth as it fuses these two images together. Anaglyph glasses are inexpensive and their method of creating 3D images is simple. However, the pictures created in your mind are monochrome and fuzzy. They also make you feel nauseous.
– The Principle in Action: Polarizing Lenses
Light travels as a wave along a particular plane. It can move along this plane in an up-down motion, in a side-to-side motion or both. In this case, you would wear polarizing lenses. Each one would polarize the light in a different way. For example, the right lens would receive light traveling in an up-down motion. The left lens would receive light moving in a side-to-side direction. That means the right and the left eye would receive two different images. Consequently, the brain would create depth as it combines these two images to form one picture. Creating 3D images is also possible through active-shutter and lenticular technology.
– Common Uses of 3D Technology
This advancement is revolutionizing society. For example, movies are now in 3D. Watching such films enhances the feeling that you are a part of what you are seeing. Moreover, 3D technology is taking the gaming world by storm. In fact, almost all video games creators are incorporating it into their latest projects. Architects are also taking advantage of it because they can use it to create an awesome presentation.

Facts About Residential Security Drones
Drones are the latest craze in the world of technology. In fact, the market for these gadgets could reach $127 billion in 2020. Currently, it stands at $2 billion annually. People use drones for a variety of reasons. The most common use of it is for military purposes where the US and other governments target terrorists with it.
However, other less controversial uses of this device exist. For example, photographers and filmmakers use it to take aerial photographs. Some companies use it to verify business claims and you can use it to improve your home security. Here are some interesting facts to know about residential security drones.
– They Can Take Pictures of Criminal Activities around Your Home
Many people think of drones as delivery items. For example, Amazon plans to use them to transport packages to their clients. Drones also carry missiles for use in military campaigns. However, residential ones are a bit different. They come with HD cameras that have 720 pixels. Others have either low or high-quality cameras depending on the manufacturer and the price you paid for it. The purpose of these drones is to help you see what is happening around your home. That means you do not have to go outside when you hear strange noises at night. Instead, you can launch your drone and it will help you see what is causing the strange noise.
– They Can Respond To Emergencies Quickly
Responsiveness is critical when it comes to enhancing security. Sometimes, it might take minutes or even hours before anyone responds to your cry for help. It may also take a lot of time before you know what the actual threat is. Residential security drones can weigh anything from 300 grams to 20 kilograms. It all depends on their features and the materials the manufacturer used to make them. That means they can fly quickly to wherever you need them to go. They can also maneuver around buildings and trees among other obstacles without much difficulty. Remember, once a potential robber is likely to run away once he sees a drone following him. You can also send the pictures taken by your drone to the police or the neighborhood watch team.
– They Are Easy To Repair and Operate
A little training is necessary before you operate a plane or install a security system. In contrast, drones are easy to run. In fact, you can operate one after you look at the manual a few times.
