Bhs Image Technology First Semester Exam

The shorter the focal length, the greater the depth of field. This is because a shorter focal length allows for a wider angle of view, resulting in more of the scene being in focus from near to far. In contrast, a longer focal length narrows the angle of view, resulting in a shallower depth of field where only a small portion of the scene is in focus.

Magenta is the complementary color of green because complementary colors are pairs of colors that, when combined, create a neutral color such as gray or white. In the RGB color model, magenta is a combination of red and blue, while green is a primary color. When magenta and green are combined, they create a neutral gray color.

The correct answer is "camera obscura". A camera obscura is a device that consists of a darkened room with a convex lens inserted in one wall. It works by allowing light to enter through the lens and project an inverted image onto the opposite wall or surface. This device was used in the past as a precursor to the modern camera, allowing artists and scientists to study and capture images.

Photographs made from tintype process were called tintypes or ferrotypes if on an iron base. The term "ferrotype" specifically refers to photographs produced on thin iron plates coated with a black or brown lacquer. This process was popular during the late 19th and early 20th centuries, as it was relatively inexpensive and produced durable images. The other options mentioned in the question, such as daguerreotypes, dry-plate, and collodion, are different photographic processes that do not involve the use of an iron base.

Selective focusing refers to the technique of intentionally focusing on a specific subject while blurring the background. By using selective focusing, a photographer can direct the viewer's attention to the subject and create a sense of depth and visual interest in the photograph. This technique is commonly used in portrait photography or when the subject needs to stand out from the surroundings.

The correct answer is "fixed" because simple cameras have a fixed aperture, which means it cannot be adjusted or changed in size. Unlike cameras with adjustable or movable apertures, simple cameras have a set aperture size that cannot be modified. This lack of flexibility in aperture size is a characteristic of basic or uncomplicated cameras.

When the lens aperture and shutter speed are set manually on a camera, it allows the photographer to have full control over the exposure settings. This means that they can adjust the aperture to control the depth of field and the shutter speed to control the amount of light entering the camera. Manual exposure gives the photographer the flexibility to achieve the desired creative effect and adapt to different lighting conditions.

Obstructions between the camera and the subject can usually be eliminated by careful placement of the camera, changing the angle, moving closer to the subject, or using a wide-angle lens. This means that any objects or obstacles that are blocking the view or causing interference can be overcome by adjusting the camera position, angle, or lens choice. By doing so, the photographer can ensure a clear and unobstructed view of the subject.

Fill light is used to supplement the main light source and brighten shadow areas. It helps to balance the lighting in a scene by filling in the areas that are not well-lit by the key light. This additional lighting is typically softer and less intense than the key light, and it helps to reduce the contrast between the light and shadow areas. The fill light can be positioned on the opposite side of the key light to provide a more even illumination or placed closer to the camera to reduce the shadows on the subject.

The photographer uses the viewfinder to see what will be photographed, read settings, and adjust focus. The viewfinder is a small window on the camera that allows the photographer to look through and see the subject before capturing the image. It helps in framing the shot, ensuring that the desired elements are included in the frame. Additionally, the viewfinder provides information about the camera settings, such as aperture, shutter speed, and ISO, allowing the photographer to make adjustments as necessary.

An enlarger is a device used in photography to project an enlarged image from a negative onto a sheet of print paper. It is an essential tool in the darkroom for producing prints of different sizes. The enlarger works by shining light through the negative and focusing it onto the paper to create a larger version of the image. This allows photographers to control the size and composition of their prints.

An enlarging lens controls the amount of light projected onto the print paper with an aperture that is the same as those found in camera lenses. The aperture is a small opening in the lens that can be adjusted to control the amount of light entering the camera. In the case of an enlarging lens, it controls the amount of light that is projected onto the print paper, allowing the photographer to adjust the exposure and achieve the desired level of brightness and contrast in the final print.

Split-image spot aids are best for very precise focusing because they provide a clear and accurate representation of the subject's focus. These aids consist of a split prism or microprism that splits the image into two halves, and when the subject is in focus, the two halves align perfectly. This allows photographers to achieve precise focus, especially when working with subjects that require fine details or shallow depth of field.

The larger the number of pixels, the finer the details the camera can potentially record. This is because a larger number of pixels means that there are more individual dots of color that make up the image. With more pixels, the camera can capture more information and provide a higher level of detail in the resulting image.

The correct answer is diaphragm. In a camera, the diaphragm is responsible for controlling the amount of light that enters the camera. It is a mechanism that can be adjusted to either enlarge or reduce the size of the aperture, which determines the amount of light that reaches the camera's sensor or film. By adjusting the diaphragm, photographers can control the depth of field and the exposure of their photographs. The other options, such as shutter, curtain, and lens, are also important components of a camera, but they do not specifically control the amount of light admitted into the camera.

The main light that sets the overall level of light intensity for something being photographed is sometimes called the "key" light. It is the primary light source that illuminates the subject and determines the overall lighting and mood of the photograph. The key light is typically positioned in front of the subject and is often the brightest light in the scene.

Framing is the technique of partially or totally surrounding the primary subject with an object or objects in the foreground. This technique is used to draw attention to the subject and create a sense of depth and context. By framing the subject, the photographer can enhance the composition and create a more visually appealing image.

A latent image refers to an image that is present but not yet visible. It is an image that is formed on a surface, such as a photographic film or a sensor, but cannot be seen until it is developed or processed. In this context, the term "latent" accurately describes the state of an image that exists but is not yet visible.

Thomas Edison is the correct answer because he introduced the movie film in 1891 using the new flexible plastic film. Edison was an American inventor and businessman who is famous for his contributions to the development of the motion picture industry. He invented the Kinetograph, a motion picture camera, and the Kinetoscope, a device for viewing films. Edison's introduction of the flexible plastic film was a significant advancement in the history of cinema, as it allowed for longer and more practical use of film in movie production.

The correct answer is "daguerreotypes." Daguerreotypes were one of the earliest forms of photography, invented by Louis Daguerre. They involved exposing an image onto a silver-coated copper plate, resulting in a unique and detailed positive print. This technique was widely used for producing portraits during the mid-19th century.

A special light fitted with a filter to screen out light that can damage black and white print paper is called a safe light. This type of light is used in darkrooms to provide illumination while preventing the paper from being exposed to harmful light wavelengths. The filter in the safe light blocks the specific wavelengths that could cause damage to the sensitive paper, ensuring that the prints are not ruined during the development process.

Light is essential for the perception of color. Without light, there would be no source of illumination to reflect off objects and stimulate our eyes, resulting in a lack of color perception. Therefore, without light, there can be no color.

The most popular type of film cameras use 35 mm film. This type of film is widely used in photography due to its versatility and availability. It offers a good balance between image quality and ease of use. 35 mm film is commonly used in both amateur and professional photography, making it the preferred choice for many photographers. It is also compatible with a wide range of camera models, further contributing to its popularity.

As the lens aperture becomes smaller, the depth of field increases. This means that a larger portion of the image will be in focus, from the foreground to the background. Smaller apertures, indicated by higher f-stop numbers, allow less light to enter the camera, resulting in a larger depth of field. This is particularly useful in landscape photography or when capturing a scene with multiple subjects at different distances, as it ensures that more of the image is sharp and in focus.

As the distance of the flash to the subject increases, the amount of light needed to make the exposure increases. This is because light diminishes as it travels further, so the flash needs to emit more light in order to reach the subject and properly expose the photograph. The rate at which the amount of light needed increases is faster, as the distance between the flash and the subject increases exponentially.

Fill flash is used to lighten the deeply shaded areas of a subject and reduce contrast when part of the subject is shaded. This technique is commonly used in photography to balance the exposure and ensure that both the shaded and well-lit areas of the subject are properly exposed. By using fill flash, photographers can achieve a more balanced and evenly lit image, resulting in a more pleasing and natural-looking photograph.

George Eastman is the correct answer because he was an American inventor and entrepreneur who introduced the 100-shot box camera in 1888. He is known for founding the Eastman Kodak Company and making photography accessible to the masses with his innovations in camera technology. His introduction of the 100-shot box camera revolutionized photography by making it more convenient and affordable for people to capture and preserve their memories.

Johann Schulze is the correct answer because he was a German physicist who discovered that certain silver salts changed colors when exposed to light. This discovery was significant in the development of photography and the understanding of light-sensitive materials. Joseph Niepce, Louis Daguerre, and William Fox Talbot were also important figures in the history of photography, but they were not specifically known for this particular discovery.

The question is asking for the other type of shutter besides the leaf shutter. The correct answer is "focal plane" because it is a common type of shutter used in cameras. The focal plane shutter is located near the focal plane of the camera and consists of two curtains that move across the image sensor or film plane to control the exposure time. This type of shutter is known for its ability to capture fast-moving subjects and create various creative effects such as motion blur.

Autochrome is the correct answer because it was the first commercially available color film. It was invented by the Lumière brothers and introduced in 1907. Autochrome used a unique process of capturing color by using dyed potato starch grains on glass plates. This breakthrough in technology allowed for the creation of color photographs, revolutionizing the field of photography and paving the way for future advancements in color film.

The 220 roll size film produces about twice as many frames as the 120 roll size film. This means that for every frame produced by the 120 roll size film, the 220 roll size film will produce two frames. Therefore, the 220 roll size film is able to capture twice the number of frames compared to the 120 roll size film.

Photographers using the wet collodion process brought portable darkrooms wherever they took pictures. The wet collodion process was a photographic technique used in the mid-19th century, which involved coating a glass plate with a mixture of collodion, chemicals, and silver nitrate. The plate had to be prepared and developed while still wet, hence the need for a portable darkroom to protect the plate from exposure to light. This process allowed for faster exposure times compared to earlier techniques, making it more suitable for outdoor photography.

A digital image sensor is a device used in digital cameras to electronically record light intensity and color. It converts the optical image formed by the camera lens into an electrical signal, which is then processed and stored as a digital image. This sensor is responsible for capturing the image and converting it into a format that can be stored and displayed on a digital camera.

Richard L. Maddox, a British physician, made the first successful dry-plate negative. This invention revolutionized photography as it eliminated the need for immediate development of the image. Unlike wet-collodion plates that required immediate processing, dry-plate negatives could be developed at a later time, providing photographers with more flexibility and convenience. This innovation played a crucial role in the development of modern photography techniques.

The depth of field preview button allows the photographer to see what will and will not be in focus with a specific aperture setting. By pressing this button, the camera adjusts the aperture to the desired setting, allowing the photographer to preview the depth of field in the viewfinder or on the LCD screen. This helps the photographer to determine which parts of the image will be sharp and in focus, and which parts will be blurred or out of focus.

Louis Daguerre discovered that a highly polished silver sheet could be made light-sensitive when exposed to iodine vapor. This discovery led to the development of the daguerreotype, an early form of photography. Daguerre's process involved exposing the treated silver plate to light, which created a latent image that could be developed and fixed to create a permanent photograph. His invention revolutionized the field of photography and paved the way for the modern cameras and photographic techniques we use today.

The correct answer is "shutter." In photography, the shutter is a mechanism that opens and closes to control the duration of the exposure, allowing light to pass through the lens and reach the film or sensor. By adjusting the speed at which the shutter opens and closes, photographers can control the amount of light that enters the camera, thus affecting the exposure and the final image. The shutter works in conjunction with the aperture (diaphragm) to regulate the amount of light that reaches the film or sensor.

When a SLR camera takes a picture, the mirror flips up automatically. This is because SLR cameras use a mirror mechanism to reflect the light coming through the lens onto the viewfinder, allowing the photographer to see exactly what will be captured in the image. However, when the picture is taken, the mirror needs to move out of the way to expose the camera's image sensor to the incoming light, hence it flips up automatically.

Resolution refers to the ability of a film or camera to capture and record fine details. It is a measure of the level of detail that can be seen in an image, typically measured in pixels. A higher resolution means that more details can be captured and displayed in the image, resulting in a sharper and clearer picture. Therefore, resolution is the correct answer as it directly relates to the ability of a film to record fine details.

The advantage of the view camera is its ability to correct distortion caused by an excessively wide or narrow angle of view. Distortion refers to the bending or warping of straight lines and shapes in an image. View cameras have movements such as tilt, shift, and swing that allow photographers to adjust the perspective and correct distortion, resulting in more accurate and realistic images.

A sunset silhouette is an example of back lighting because the light source is behind the subject, creating a strong contrast between the subject and the background. This positioning of the light creates a halo effect around the subject, obscuring details and emphasizing the outline or shape of the subject. In the case of a sunset silhouette, the subject appears as a dark figure against the colorful and bright background of the setting sun.

Edwin Land is the correct answer because he is the inventor of Polaroid instant photography. He created this technology in 1947, which allowed for the production of finished black and white photographs in just 60 seconds. Thomas Edison, George Eastman, and William Fox Talbot are not associated with the invention of Polaroid instant photography.

Depressing the shutter release halfway adjusts the focus and exposure. When the shutter release button is pressed halfway, the camera's autofocus system is activated, allowing it to adjust the focus on the subject. At the same time, the camera's light metering system measures the available light and determines the appropriate exposure settings for the shot. This includes adjusting the aperture, shutter speed, and ISO to achieve a well-exposed image. Therefore, depressing the shutter release halfway not only ensures a sharp focus but also sets the correct exposure for the photograph.

As lens and camera design and photographic processes improved, shorter exposures made portrait photography popular. This is because portrait photography typically requires the subject to remain still for a longer period of time, allowing for a more detailed and focused image. With shorter exposures, photographers were able to capture portraits more quickly and efficiently, resulting in the increased popularity of this genre.

SLR (Single Lens Reflex) and TLR (Twin Lens Reflex) cameras are fitted with ground glass focusing screens. This type of screen allows the photographer to view the image through the lens, providing an accurate representation of what will be captured. Ground glass screens are made by grinding glass to a very fine and smooth surface, which helps to ensure clear and precise focusing. The other options, such as lens, mirror, and polished plastic, are not commonly used as focusing screens in SLR and TLR cameras.

Telephoto and close-up lenses are designed to magnify the subject, which can make any slight movement or shaking of the camera more noticeable. This means that camera shake becomes more emphasized when using these lenses. The longer focal length of telephoto lenses and the close proximity to the subject with close-up lenses both contribute to this effect. Therefore, camera shake is the correct answer.

After the film has undergone the developing process, it is referred to as a negative. A negative is an image that has the opposite tonal values of the original scene, with dark areas appearing light and light areas appearing dark. The negative is used to create positive prints or transparencies, which accurately represent the original scene.

Joseph Niepce, a Frenchman, is credited with creating the world's first photograph by spreading a light-sensitive varnish on a polished metal plate and exposing it in a modified camera obscura.

Bracketing means taking several identical pictures using aperture settings or shutter speeds on either side of the recommended meter calculation. This technique is commonly used to ensure that at least one of the images will have the correct exposure. By capturing multiple shots with different settings, photographers can increase the chances of getting a perfectly exposed image, especially in challenging lighting conditions. Bracketing is particularly useful in situations where the dynamic range of the scene exceeds the capabilities of the camera's sensor, such as high contrast scenes or when shooting in difficult lighting conditions.

A negative carrier is a device used in an enlarger to hold the negative securely and flat. It ensures that the negative remains in the correct position and prevents any movement or distortion during the enlarging process. This allows for precise and accurate printing of the negative onto the photographic paper.
