How does a camera obscura differ from a regular camera? (1 point)
1. A regular camera does not capture images.
2. A camera obscura does not preserve images.
3. A regular camera cannot be made of cardboard.
4. A camera obscura is a much more complex machine.
4. A camera obscura is a much more complex machine.
The correct answer is 4. A camera obscura is a much more complex machine. A camera obscura is an optical device that uses a small hole or lens to project an image of the surroundings onto a surface, such as a wall or screen. It can be made from simple materials like cardboard or a small pinhole, but it is a relatively simple mechanism. On the other hand, a regular camera is a more advanced device that can capture and preserve images using various lenses, sensors, and mechanisms.
To determine the difference between a camera obscura and a regular camera, we need to understand their basic characteristics.
A camera obscura, also known as a pinhole camera, is a simple optical device that projects an image onto a surface using the principles of light passing through a small hole. It consists of a light-tight box or room with a small hole on one side and a screen or surface on the opposite side. When light enters through the hole, an inverted and reversed image of the scene outside is formed on the screen.
On the other hand, a regular camera, such as a digital camera or a film camera, is a complex machine designed to capture and preserve images. It uses a combination of lenses, sensors, and mechanisms to focus, expose, and record images onto digital sensors or photographic films. Regular cameras provide options for adjustments and settings like aperture, shutter speed, and ISO sensitivity to enhance the image quality and control the exposure.
Based on this information, the correct answer would be:
4. A camera obscura is a much more complex machine.
While a camera obscura can be made from simple materials such as a cardboard box, it lacks the intricate mechanisms and advanced features of a regular camera, making it a less sophisticated device in terms of capturing and preserving images.
Which BEST explains why photojournalism did not emerge until the Civil War? (1 point)
1. Camera technology had to become portable and create quality images.
2. There were few practical uses for photography prior to the Civil War.
3. People had a lot of concerns about photographing the dead in previous eras.
4. The Civil War was the first war to receive widespread coverage in the press.
The correct answer is:
4. The Civil War was the first war to receive widespread coverage in the press.
Photojournalism did not emerge until the Civil War primarily because it was the first war to receive extensive and widespread coverage in the press. The advancements in printing technology and the growing demand for news and information led to the need for visual documentation of events. Photographers could now travel with armies, capture images on the front lines, and send them back to be published in newspapers and magazines. This newfound coverage of war through photography helped pave the way for the development of photojournalism as a profession.
What was the primary limitation on photographs taken by Nicéphore Niépce ? (1 point)
1. They took eight hours to create.
2. They could not include moving people.
3. They required silver chloride, which was rare.
4. They would continue to darken if exposed to light.
The correct answer is:
1. They took eight hours to create.
One of the primary limitations of photographs taken by Nicéphore Niépce, one of the pioneers of photography, was that they took an extensive amount of time to create. The earliest form of photography known as heliography, which Niépce developed, required an exposure time of several hours to capture an image. This long exposure time made it challenging to capture moving objects or people, as any movement during the exposure would result in a blurry or distorted image. Therefore, the correct answer is option 1.
How would getting wedding pictures taken today differ from getting them taken in the mid-1800s? (1 point)
1. In the 1800s no one was able to get wedding pictures taken.
2. Today professional photographers take wedding photographs.
3. Today couples have many pictures taken and choose favorites.
4. In the 1800s photography was only for when people died, not weddings.
The correct answer is:
3. Today couples have many pictures taken and choose favorites.
Getting wedding pictures taken today differs from getting them taken in the mid-1800s in that couples now have the opportunity to have many pictures taken and select their favorites. In the mid-1800s, photography was still in its early stages, and the process was time-consuming and required long exposure times. It was not common for couples to have multiple photographs taken during their wedding day. In contrast, with modern technology and the widespread availability of professional photographers, couples can now have numerous photos taken throughout their wedding day. These photos can include various poses, angles, and moments, allowing couples to choose their favorite images for preservation.
