When taking a picture with a digital camera, you can ensure it is well focused by doing what?
Correct Answer
D. Pressing The Shutter Halfway First
Explanation
Pressing the shutter halfway first allows the camera to autofocus and adjust the focus on the subject. This technique is known as "half-pressing" the shutter, and it gives the camera time to analyze the scene and make sure the subject is in focus before fully pressing the shutter release button to capture the image. By doing this, you can ensure that your picture is well focused.
2.
In the abbreviation "SLR", what does the "R" stand for?
Correct Answer
A. Reflex
Explanation
The correct answer is "Reflex". In the abbreviation "SLR", the "R" stands for "Reflex". SLR is commonly used to refer to a Single-Lens Reflex camera, which is a type of camera that uses a mirror and prism system to allow the photographer to see exactly what will be captured by the camera's lens.
3.
What is photographic shutter speed measured in?
Correct Answer
C. Seconds
Explanation
Photographic shutter speed is measured in seconds. Shutter speed refers to the length of time that the camera's shutter remains open, allowing light to enter and expose the camera's sensor or film. It determines the amount of time the camera sensor is exposed to light, thereby controlling the amount of light that reaches the sensor and affects the image. Shutter speeds are typically measured in fractions of a second, such as 1/1000, 1/250, or 1/30, but can also be measured in full seconds for long exposure photography.
4.
What type of metal is used to produce a daguerreotype photograph?
Correct Answer
A. Silver
Explanation
Daguerreotype photographs were produced using a process that involved exposing a silver-coated copper plate to light. The plate was then developed using mercury vapor, which created a visible image. Therefore, the correct answer is Silver.
5.
A camera that has few or no adjustments to be made by the picture-taker is generally called a what?
Correct Answer
C. Simple Camera
Explanation
A camera that has few or no adjustments to be made by the picture-taker is generally called a "Simple Camera". This term refers to a camera that is easy to use and requires minimal technical knowledge or adjustments. It is designed for individuals who prefer a straightforward and user-friendly experience when taking pictures.
6.
What feature of a camera eliminates parallax error?
Correct Answer
D. Single Lens Reflex
Explanation
The feature of a camera that eliminates parallax error is the Single Lens Reflex (SLR) system. In an SLR camera, a mirror is placed between the lens and the film/sensor, which reflects the light coming through the lens into the viewfinder. This allows the photographer to see exactly what the lens sees, eliminating any parallax error. When the shutter is released, the mirror flips up, allowing the light to reach the film/sensor and capture the image.
7.
On an overcast day, a photographer is likely to encounter what kind of lighting?
Correct Answer
A. Soft Lighting
Explanation
On an overcast day, the clouds act as a diffuser, scattering the sunlight and creating soft lighting conditions. Soft lighting is characterized by gentle and even illumination, with minimal shadows and reduced contrast. This type of lighting is ideal for portrait photography as it produces flattering and natural-looking results, as well as for capturing details and textures in landscapes. It helps to avoid harsh shadows and highlights, resulting in a more balanced and pleasing image.
8.
In photography, what word refers to film's sensitivity to light?
Correct Answer
B. Speed
Explanation
The word "speed" in photography refers to film's sensitivity to light. Film speed determines how quickly the film reacts to light and how much light is needed to create a properly exposed image. A higher film speed (such as ISO 800) is more sensitive to light and requires less light to create a properly exposed image, while a lower film speed (such as ISO 100) is less sensitive to light and requires more light for a proper exposure.
9.
The first autofocus camera was marketed in what decade?
Correct Answer
C. 1970's
Explanation
In the 1970s, the first autofocus camera was marketed. This means that before the 1970s, cameras did not have the ability to automatically focus on the subject. The development and introduction of autofocus technology in cameras revolutionized the photography industry, making it easier for photographers to capture sharp and clear images. The 1970s marked a significant advancement in camera technology, allowing photographers to focus more on composition and creativity rather than manually adjusting the focus.
10.
The first commercial color film, invented by the French Lumiere brothers in 1907, was called?
Correct Answer
C. Autochrome Plates
Explanation
Autochrome Plates is the correct answer because the Lumiere brothers invented the first commercial color film in 1907, which was known as Autochrome Plates. This film used glass plates coated with microscopic grains of potato starch dyed in red, green, and blue. When a photograph was taken using this film, the light would pass through these colored grains and create a full-color image. Autochrome Plates revolutionized color photography and became widely popular in the early 20th century.
11.
What is the compensation for the color temperature associated with a given set of lighting conditions?
Correct Answer
D. White Balance
Explanation
White balance is the compensation for the color temperature associated with a given set of lighting conditions. It is used to ensure that the colors in a photograph appear accurate and natural, regardless of the type of lighting present. Different light sources emit light with different color temperatures, such as warm yellowish light from incandescent bulbs or cool bluish light from daylight. By adjusting the white balance, the camera can neutralize the color cast caused by the lighting conditions and produce a more accurate representation of the colors in the scene.
12.
Which lens has a focal length that is substantially shorter than the focal length of a normal lens?
Correct Answer
C. Wide-Angle Lens
Explanation
A wide-angle lens has a focal length that is substantially shorter than that of a normal lens. Wide-angle lenses have a wider field of view, allowing them to capture more of a scene in a single frame. They are commonly used in landscape photography or situations where you want to include more of the surroundings in the image.
13.
Who created the first photograph on paper of a human figure in 1840?
Correct Answer
D. William Henry Fox Talbot
Explanation
William Henry Fox Talbot is credited with creating the first photograph on paper of a human figure in 1840. Talbot was a British scientist and inventor who developed the calotype process, a precursor to modern photography. He made significant contributions to the field of photography, including the invention of the negative-positive process, which allowed multiple copies of an image to be produced. Talbot's photograph, titled "The Open Door," depicted a view of a doorway with a servant girl standing in the frame. This groundbreaking achievement paved the way for the future development and popularization of photography as an art form.
14.
