A Neutral Density (ND) Filter does the following:
Correct Answer
B. Reduces the amount of light entering the camera
Explanation
An ND filter is a type of filter that is used in photography to reduce the amount of light that enters the camera. It does not change the color of light or convert incandescent light to outdoor or fluorescent light. Its main purpose is to allow photographers to achieve certain creative effects by controlling the amount of light that reaches the camera sensor. By reducing the amount of light, it helps in situations where there is too much light, such as when shooting in bright sunlight or when using a wide aperture in low-light conditions.
2.
Three point lighting utilizes these three lighting elements.
Correct Answer
C. Key, back light and Fill
Explanation
The correct answer is Key, back light and Fill. Three point lighting is a standard lighting technique used in photography and videography. It involves using three different light sources to properly illuminate a subject. The key light is the main light source and provides the primary illumination on the subject. The back light, also known as the rim light or hair light, is positioned behind the subject and adds depth and separation from the background. The fill light is used to fill in the shadows created by the key light and soften the overall lighting. This combination of key, back light, and fill light creates a balanced and visually pleasing lighting setup.
3.
A flood light is the exact opposite of a spotlight.
Correct Answer
A. True
Explanation
A flood light is designed to provide a wide and even distribution of light, illuminating a large area. It is typically used for outdoor lighting or in large indoor spaces. On the other hand, a spotlight is designed to focus a narrow and intense beam of light on a specific area or object. It is commonly used for highlighting or directing attention to a particular point. Therefore, a flood light and a spotlight have opposite characteristics in terms of their light distribution and purpose.
4.
When using a standard 3 point lighting set-up, the Key light is half the intensity of the Fill light.
Correct Answer
B. False
Explanation
In a standard 3 point lighting set-up, the Key light is actually the main light source and is typically the brightest light. It provides the primary illumination and sets the overall tone and mood of the scene. The Fill light, on the other hand, is used to fill in the shadows created by the Key light and is usually set at a lower intensity to create a more balanced lighting effect. Therefore, the statement that the Key light is half the intensity of the Fill light is false.
5.
If I wanted to change the color of an indoor lighting fixture I would use a:
Correct Answer
B. Gel
Explanation
A gel is a colored transparent material that is used to change the color of light in a lighting fixture. It is commonly used in theater, film, and photography to create different lighting effects or to match the color temperature of different light sources. By placing a gel over the lighting fixture, the color of the light can be altered to achieve the desired effect or mood.
6.
_______________will direct and prevent light from projecting onto the subject.
Correct Answer
Barndoors
Barn doors
Explanation
Barndoors or barn doors are adjustable flaps or panels that are attached to the front of a light source, such as a studio light or a camera flash. They are used to control the direction and spread of light by blocking or shaping the light beam. By adjusting the position and angle of the barndoors or barn doors, the photographer or cinematographer can prevent unwanted light from projecting directly onto the subject, resulting in more controlled and focused lighting.
7.
____________________ bulbs make light by heating a metal filament wire to a high temperature until it glows.
Correct Answer
Incandescent
Explanation
Incandescent bulbs make light by heating a metal filament wire to a high temperature until it glows. This is achieved by passing an electric current through the filament, which causes it to heat up and emit light. The high temperature causes the filament to emit visible light, creating illumination. Incandescent bulbs are known for their warm and natural light, but they are not very energy-efficient and have been largely replaced by more efficient alternatives such as LED bulbs.
8.
The lumen measures of the total "amount" of visible light emitted by a source.
Correct Answer
A. True
Explanation
The lumen is a unit of measurement used to quantify the total amount of visible light emitted by a source. It is a measure of the brightness or intensity of the light, rather than the specific color or wavelength. Therefore, it is true that the lumen measures the total "amount" of visible light emitted by a source.
9.
__________________ is a unit of measure of the intensity of light falling on a surface.
Correct Answer
Footcandle
foot candle
Explanation
Footcandle (also spelled foot candle) is a unit of measure used to quantify the intensity of light that falls on a surface. It is defined as the illuminance produced by a source of one candela at a distance of one foot. In other words, it measures the amount of light that reaches a specific area or surface.
10.
Correct Answer
C. Barn Doors
Explanation
Barn doors are a type of accessory used in photography and filmmaking. They are typically attached to a light source, such as a light box, to control the direction and intensity of the light. By adjusting the position of the barn doors, the photographer or filmmaker can block or shape the light, creating different lighting effects and preventing unwanted light spill. This helps to enhance the overall composition and mood of the scene. Therefore, barn doors are an essential tool in controlling and manipulating light in photography and filmmaking.
11.
Correct Answer
A. Fluorescent Light Bulbs
Explanation
Fluorescent light bulbs are the correct answer because they are a type of light bulb that uses fluorescence to produce visible light. Unlike incandescent bulbs, which use a filament to produce light, fluorescent bulbs use a gas and a phosphor coating to create light. They are known for their energy efficiency and long lifespan compared to other types of bulbs.
12.
Correct Answer
A. Fresnel Spotlight
Explanation
The correct answer is "Fresnel Spotlight." The given options are different types of lighting equipment, and the correct answer is one of them. A Fresnel Spotlight is a type of spotlight that uses a Fresnel lens to control the spread and intensity of light. It is commonly used in theater, film, and photography to illuminate specific areas or subjects on stage or set.
13.
Correct Answer
C. Scoop
14.
Correct Answer
D. Incandescent
Explanation
The correct answer is Incandescent. Incandescent refers to a type of light bulb that produces light by heating a filament inside the bulb until it glows. This type of lighting is commonly used in household lamps and fixtures. It emits a warm, yellowish light and is known for its high energy consumption and shorter lifespan compared to other types of lighting.
