TERMINAL QUESTIONS
1. What do you understand by the term ‘photography’. Explain the significance of photography in our day to day life.
Ans. We always see photographs around us. Behind the bus, on the sign boards, on the walls, in newspapers and magazines. Photos in newspapers and magazines inform us about an event or an incident. Remember the tsunami? One must have seen its pictures on newspapers as well as on television. It was these pictures that gave us information about such a big disaster.
These days pictures are as important to as the written or printed word. In fact in a country like our where still many people cannot read or write, photos have a greater use and a greater impact. Photographs are seen along with the written news in magazines and newspapers and they add to the impact of the news and convince us about the truth of the event we are reading about.
Modern photography was invented by two Frenchmen Joseph Niepce and Louis Daguerre. It was in 1827 that Niepce took what we know of as the first photograph. Niepce’s partner Louis Daguerre made further improvements to the technology of taking photos and since 1839 photography became available to everyone who wanted to try it.
Photography literally means ‘drawing with light’.
As we can make out the word ‘photography’ is made of two words. Whereas ‘photo’ means ‘light’, ‘graphy’ stands for ‘graphic’ which means drawing. So once man learnt to copy an image with the help of a camera, the process started being called photography.
2. Describe the history and evolution of photography.
Ans. all know that right from prehistoric times when man began communicating, he started drawing images. This idea of pictures grew form refined drawing and to painting. In the first half of the nineteenth century, the technology of photography was invented. We could at last make pictures that were exact copies of a scene of a person. The camera along with the film made photography a reality. Human beings have known for a long time of a device which has shown an outside image on a wall or screen but the moment the light was gone, the image has disappeared. Such a device is called a pin-hole camera or the camera obscura.
This pin-hole camera was invented by the Greeks in ancient times and people through ages have used it. What really made photography possible was the discovery of chemicals that could record the effect of light and make the picture permanent, so that it may not fade away with time.
It must be mentioned here that for the first fifty years photography was nowhere as easy as we think of it today. The cameras were huge and had to be kept on a stand to be operated. Our great grandparents would go to a studio where they would have had to sit still in front of the camera to have a photograph made. It was much later in the 1900s that easy to use light cameras were made which could be carried anywhere with ease and used without the support of a stand.
3. Illustrate the differences between film and digital photography.
Ans. FILM CAMERA
1. Records image on a chemically sensitive film to make a picture negative.
2. A film has to be processed into an optical negative.
3. A film camera is bigger and can work without batteries.
4. Pictures from a film camera have to be printed in a lab.
5. Pictures from a film camera have to be physically sent and this can take time.
DIGITAL CAMERA
1. Records the photo as a digital signal that is stored on a chip.
2. A digital image can be instantly seen on the camera. No processing is required and so there are no negatives.
3. A digital camera is much smaller and always need batteries.
4. Photos from a digital camera can be copied on a computer and printed as well.
5. Photographs from a digital camera can easily be sent through a computer by email.
Very Short Type Questions Answer
1. What do photos in newspapers and magazines do?
Ans. Photos in newspapers and magazines inform us about an event or an incident.
2. Which instrument did the role of camera just before the invention of camera?
Ans. Pin-hole camera.
3. Which discovery made photography possible?
Ans. The discovery of chemicals that could record the effect of light and make the picture permanent, so that it may not fade away with time.
4. Who invented modern photography?
Ans. Modern photography was invented by two Frenchmen Joseph Niepce and Louis Daguerre in 1827.
5. Who made improvement in photography invention?
Ans. Louis Daguerre in 1839.
6. What is literal meaning of photography?
Ans. Photography literally means ‘drawing with light’.
7. What are two components of photography?
Ans. Camera and film.
8. What is an optical process?
Ans. The negative film acquires an image. With the help of lights it is called an optical process.
9. What is new technology of photography called?
Ans. Digital photography.
10. Give a benefit of digital camera.
Ans. It is cheap and easy to handle.
Short Type Questions Answer
1. How can we see the picture that we have taken?
Ans. Photography has two important components; one is the camera and the other is the film. A film is sensitive to light, so when we expose it to a screen with the click of the button, the impression of light is left on the film. This film is then processed in the laboratory and we see the picture that we have taken.
2. What is negative image?
Ans. The image on the film is in the form of a negative, meaning the dark areas appear light and the light areas appear dark.
3. What two things make digital photography useful?
Ans. There are two important factors that make digital photography very useful. One is that the picture taken can be seen on a screen behind the camera immediately and the second reason is that digital photography does not require any film.
4. What are advantages of digital photography?
Ans. The camera records the image taken on a memory chip that is inside it. Once the chip is filled with the photos, these photos can be copied onto a computer to reuse the camera by making fresh space for taking more photographs. The ability of the camera to link itself to the computer makes it easy to print the picture and to send pictures to any part of the world through the internet. Not only this, the computer allows the photograph that has been taken to be improved and cleaned with the help of a number of software programmed that are available. So, the future of photography is going to be digital.
Long Type Questions Answer
1. Describe film photography.
Ans. Photography has two important components; one is the camera and the other is the film. A film is sensitive to light, so when we expose it to a screen with the click of the button, the impression of light is left on the film. This film is then processed in the laboratory and we see the picture that we have taken.
Let’s know what happens inside the lab. Here the film is taken out of its container in complete darkness. As the film has a layer of light sensitive chemical on it, the chemical is given a wash with certain other chemicals. This helps in bringing out the picture on the film because the effects of all the chemicals are washed away and the image on the film is fixed and made visible to the eye. Now the image on the film is in the form of a negative, meaning the dark areas appear light and the light areas appear dark. Now light is thrown through the negative film on to a photographic paper that is sensitive to light in the same way as the film was sensitive to light. This paper is also given a chemical wash thus creating the final picture; so we see that from taking the picture to the final print there are many stages involved. Since the negative film acquires an image with the help of light, it is called an optical process.
