Physics in Cameras

Photography, meaning “drawing with lights” in Greek, is an art as well as a science of capturing light and storing it on a medium with unprecedented accuracy. Yet, up until the late 18th century, history was mainly recorded through the techniques of painting and the press. These mediums unarguably contained a certain degree of a truth, though, it was not uncommon for events, such as war to be composed with glorified details, or an unfavorable bias from the artist at hand. Beginning in the 1830’s, cameras provided a revolutionary solution by combining the advancements in optics and chemistry. Consequently, the new medium of photography was established and forever changed how history would be visually captured. Unlike other methods, photography

Photographs have been circling the world for years now . There are many different types of cameras, but only some have changed and revolutionized the world. The history behind them and the history it has captured throughout the years has impacted the world in numerous ways. It is very important to know how certain things like lighting and angle affect the outcome of photographs. To be able to capture a perfect photograph one will have to understand how lighting , angle , third rule affect a photograph. Not only are there different types of ways to take photographs but different types of photography.

It was invented by George Eastman and you can capture images and videos that could last a lifetime with a camera. For most Americans cherishing memories is crucial to them. And the camera helps you do just that. You could take a picture on April 8th, 2003 and come back to it years later. The camera is not only useful for cherishing memories. You can use it for education, learning about our history, and keeping up with what's going on in our society. Without cameras we wouldn't be able to know major events that happened in the past. For example, imagine if there were no pictures of the Holocaust, would as many people believe it happened? The camera was important in industrialization because people could now have faster way to capture significant moments in history without drawing or painting them. Cameras are still a big part of our society today. They play big role in entertainment. Also, because of cameras we can see what's happening in other parts of the world. Overall the uses for a camera will always be vital in our current

Light is a form of energy that behaves in some ways like waves. Light waves have a range of wavelengths. A wavelength is the distance between any point on one wave and the corresponding point on the next wave. Different wavelengths of light appear to us as different colors. Light that contains all wavelengths in the same proportions as sunlight appears white. See LIGHT.

the envelope. The authors also explores on the possibilities of tiny cameras that will able to

Sense the invention of the camera in 1826 photography has been used to document everything from family portraits, social injustice, sporting events, world news, expressions of joy and sorrow, and hundreds of monumental moments. The camera has given man the power to reveal the truth visually. Throughout history photographs have made enormous impacts on social consciousness and ultimately shaped public opinion on many pressing issues in society. Although photography is often considered a casual pastime, the invention of the camera has contributed to many aspects of history, science, and other important pieces of todays world.

The purpose of my study is to give people a chance to understand what is the meaning of photography and how it was invented, plus how people was able to take photographs before the camera was invented.

Cameras have also greatly impacted America through education. There are three types of learners, experience, audible, and visual learners. Visual learning is a teaching and learning style in which ideas, concepts, data, and other information are associated with images and techniques. Pictures actually help teach or convey the message in books or ideas predicted. In science, class they might talk about a cell and show you a diagram. If the Diagram was not there would you still be able to understand what the cell looks like? Pictures truly have changed now the new generation leers about the

Photography serves many purposes and since its invention people have used it for many different reasons, but mostly for

Photography is a word derived from the Greek words photos light and to draw. A scientist called Sir John F.W. Herschel, which was in 1839, first used the word. It was a method which was all about recording images by using light or radiation on a sensitive material. The first known camera was created by Alhazen also known as who lived around 100AD he invented the first pinhole camera this camera was used to capture the movement of the sun. Photography was explained to be the science and art of documenting photographs by capturing light on a light sensitive material which included film or an electronic sensor. Light could be reflected from objects which could expose a chemical or electronic material during a timed exposure which is typically used through a camera which can store the information chemically or electronically. The first photograph was take in 1827 taken by Joseph Nicephore Niepce who made the first photograph

To conclude, the camera has both positive and negative sides. It has helped us in so many ways from security, remembering the past, to help solving crimes and mysteries. Thanks to the camera, it is almost impossible to not have memories. Without the camera, the world would not be as intelligent as it is now, and hopefully the camera can continue to help people learn. Cameras are now the essence of the lives of modern day generation. The camera was the greatest invention of the 19th century because of the expanse of information it has given

While the original Daguerreotype started a massive surge on photography, two later inventions turned photography social phenomenon that became ingrained in our lives today. The first of these inventions is called the “calotype” process. invented in 1839 by William Henry Fox Talbot this method of photography involved exposing chemically treated paper, producing a “negative” that could be redeveloped. This allow for multiple copies of the same image to be printed, and is the predecessor to modern film photography. The next major breakthrough in the art of photography was the portable camera. Before its inception, most photos were taken using a large, cumbersome device that worked as a camera and darkroom for developing glass plates coated with a sticky collodion solution. (film photography was

Photographs are created from light rays bouncing off objects. When a person looks through the viewfinder, the image they see are light rays reflected from a penta-prism, a specially shaped piece of glass inside the camera. The rays from the penta-prism came from a mirror, which reflected the rays it received from the lenses. Lenses are used to focus in or out on objects. They attain the rays from the object reflecting the rays toward the camera. For an image to be “captured” on a film camera, the button used to take

Until recently, at least, it was possible to define photography as a process involving optics, light sensitive material and the chemical processing of this material to produce prints or slides. Today though, that definition is subject to change. Technological innovations…are shifting photography from its original chemical basis towards electronics… It is not overstating it to say that the advent of this new technology is changing the very nature of photography, as we have known it. (Bode and Wombell 1991)

With today’s science, light becomes more specifically perceived as a spectrum. The specific name for this spectrum is the electromagnetic spectrum, which contains many types of waves (NASA, Electromagnetic Spectrum). In Figure 2, the spectrum shows a variety of wavelengths with specific wavelengths classified by its length. The range of wavelengths humans can see wavelengths that are around 400 – 700 nanometers (nm) as colors while all other electromagnetic waves are simply blind to humans. The interesting classes for light that are used to measure are microwave and infrared light. The laser is
