Cinematography Exam II (Timed)

A 50mm lens is considered a "normal" lens on a 35mm camera because it closely replicates the field of view that the human eye sees. This means that when you look through a 50mm lens on a 35mm camera, the resulting image will closely resemble what you would see with your own eyes in terms of perspective and magnification.

Tungsten light has a color temperature of 3,200K. Color temperature is a way to describe the color appearance of light, specifically how "warm" or "cool" it appears. Tungsten light is known for producing a warm, yellowish light, and a color temperature of 3,200K falls within the warm range.

The given information states that the lighting ratio is 4:1, with the key light being at an intensity of 5.6. The fill light is mentioned as 2.8, but since the question is asking for the correct answer, it can be inferred that the fill light intensity should be equal to the key light intensity. Therefore, the correct answer would be 5.6.

The answer 2.8 refers to the fill light intensity in relation to the key light intensity. In a 2:1 lighting ratio, the key light is set at an intensity of 4. The fill light, which is used to reduce shadows created by the key light, would be set at an intensity that is half of the key light intensity. Therefore, the fill light intensity would be 2.8 (half of 4).

The color temperature of mid-day is 5,600K. Color temperature is a measurement of the color appearance of light, specifically how "warm" or "cool" it appears. The higher the color temperature, the cooler the light appears. Mid-day sunlight is generally considered to have a neutral or slightly cool appearance, which corresponds to a color temperature of around 5,600K.

The given answer suggests that the fill lighting ratio is 1 in relation to the key lighting ratio of 2. In a 4:1 lighting ratio, the key light is twice as bright as the fill light. Therefore, if the key light has a ratio of 2, the fill light would have a ratio of 1, indicating that it is half as bright as the key light.

A "normal" lens refers to a lens that has a focal length that is approximately equal to the diagonal measurement of the camera's image sensor or film frame. In this case, the focal length of the lens is 25mm, which is considered "normal" for a 16mm camera.

The correct answer is 1 because a lighting ratio of 8:1 means that the key light is 8 times brighter than the fill light. Since the key light has an intensity of 2.8, the fill light should have an intensity of 1 to maintain the 8:1 ratio.

The given answer "16:1" and "16 1" both represent the same lighting ratio. The key light is set at 5.6 and the fill light is set at 1.4. The lighting ratio is calculated by dividing the key light intensity by the fill light intensity. In this case, 5.6 divided by 1.4 equals 4. Therefore, the lighting ratio is 16:1 or 16 1.

The given equation is a combination of ISO (International Standards Organization) film speed, a FLB (Fluorescent Light Blue) filter, and an 85 color correction filter. The FLB filter is used to correct for the greenish tint produced by fluorescent lighting, while the 85 filter is used to correct for the bluish tint produced by tungsten lighting. Adding these filters to the ISO film speed adjusts the effective film speed. In this case, the result is an ASA (American Standards Association) film speed of 16. ASA is a different film speed scale used in the United States.

In the given equation, 640ASA represents a certain value of ASA. Adding ND3 and 85 to it will result in the final value of ASA. Since the equation is asking for the final value of ASA, the answer is 200.

The given equation involves adding the values of 250ASA, ND9, and 85. Since ASA and ND are both measures of film speed or sensitivity to light, they can be added together. The result of adding 250ASA and ND9 is 259ASA. Further adding 85 to this value gives a final result of 344ASA. Therefore, the correct answer is 344ASA, not 20.

The given equation involves adding three values: 3200ASA, ND9, and 80A. The answer is stated as 100ASA. This suggests that the addition of the three values results in a sum of 100ASA.

The given equation represents the combination of three different factors: 500ASA, ND6, and 80A. These factors are being added together to find the resulting value in ASA. Since there is no multiplication or division involved, we can simply add the numerical values of the three factors: 500 + 6 + 80 = 586ASA. Therefore, the correct answer is 586ASA, not 32ASA as stated in the given answer.

The correct answer is 2,800K. The color temperature of a household bulb refers to the color appearance of the light it produces. A higher color temperature indicates a cooler, bluish-white light, while a lower color temperature indicates a warmer, yellowish-white light. A color temperature of 2,800K falls in the range of warm white light, making it suitable for creating a cozy and comfortable atmosphere in a household setting.

The color temperature of late afternoon is typically warmer and more golden in hue compared to other times of the day. A color temperature of 4,800K is a higher value, indicating a cooler and bluer light. Therefore, it is not the correct answer for the color temperature of late afternoon.

The answer is correct because it accurately identifies the film stocks that are suitable for daylight and tungsten lighting conditions. 50ASA is a daylight film stock, as it is designed to be used in natural daylight. 500ASA is a tungsten film stock, as it is specifically balanced for use in artificial tungsten lighting. 250ASA is also a daylight film stock, as it is intended for use in natural daylight.

The color temperature of candle light is 1,800K. Color temperature is a way to measure the color appearance of light sources, and it is measured in Kelvin (K). Lower color temperatures, such as 1,800K, indicate warmer or more yellowish light, while higher color temperatures indicate cooler or bluer light. Since candle light has a warm, yellowish glow, the color temperature of 1,800K is an appropriate choice.

The color temperature of sunrise and sunset is typically around 2,000K. This low color temperature creates a warm, golden hue in the sky, giving a calm and peaceful atmosphere. The lower the color temperature, the warmer the light appears.
