Digital Cinematography I Assessment Review

Explanation
The correct answer is 1/3 stop. This means that on the fs100 camera, you can adjust the f-stop in increments of 1/3 stop. This allows for more precise control over the exposure settings, giving the photographer more flexibility in capturing the desired image. Adjusting the f-stop in smaller increments can help in situations where the lighting conditions are challenging or when a specific depth of field is required.

Explanation
Shutter speed is measured in fractions of a second, not in percent or angle. The angle is a measurement used in photography to describe the field of view or the extent of the scene that the camera lens can capture. Speed can refer to the sensitivity of the camera sensor or the rate at which the camera captures images, but it is not directly related to measuring the shutter speed. Therefore, the correct answer is "Angle" as it is the only option that is related to photography and can be measured.

Explanation
A .6 ND filter would reduce light entering the lens by 2 stops. ND filters are used to decrease the amount of light that reaches the camera sensor, allowing for longer exposures or wider apertures in bright conditions. The number value of the ND filter indicates the amount of light reduction it provides. A .6 ND filter is equivalent to reducing the light by 2 stops, meaning it decreases the amount of light entering the lens by a factor of four.

Explanation
A 50mm lens is considered to be the closest to human vision because it closely matches the perspective and field of view of the human eye. This focal length is often referred to as a "normal" lens as it produces images that closely resemble what we see with our own eyes. It is neither too wide nor too narrow, making it a popular choice for various types of photography, including portraits and street photography.

Explanation
A fixed focal length lens is commonly known as a prime lens. Unlike zoom lenses, which have a variable focal length and can zoom in and out, prime lenses have a fixed focal length. Prime lenses are known for their high image quality, wide maximum aperture, and compact size. They are often preferred by photographers who prioritize image sharpness and low-light performance. Therefore, the correct answer is prime lens.

Explanation
The common Kelvin temperature for outside white balance is 5600. This is because 5600 Kelvin represents the color temperature of natural daylight, which is often used as a reference point for setting white balance in outdoor photography. By setting the white balance to 5600 Kelvin, the camera can accurately reproduce colors under natural lighting conditions.

Explanation
The correct answer is "Picture profile." The Picture profile menu option on the FS100 allows users to store and change looks for the camera. This feature allows for customization of the camera settings, such as contrast, saturation, and color tone, to achieve the desired aesthetic for the footage. By saving different picture profiles, users can easily switch between different looks without having to manually adjust the settings each time.

Explanation
A variable focal length lens, also known as a zoom lens, allows the photographer to adjust the focal length and thus change the magnification and field of view. This lens is versatile as it can zoom in to capture distant subjects (telephoto) or zoom out to capture a wider scene (wide-angle). In contrast, a prime lens has a fixed focal length and cannot zoom in or out. Therefore, the correct answer is "Zoom lens."

Explanation
A fast shutter speed is the correct answer because it allows the camera to capture an image quickly, freezing the motion and reducing motion blur. A slow shutter speed would result in a longer exposure time, causing more motion blur to be captured in the image. No shutter speed is not a valid option as it would mean the camera is not capturing any image at all.

Explanation
A histogram is used on the fs100 to show you exposure. A histogram is a graphical representation of the distribution of tones in an image. It displays the brightness levels of pixels in the image, with the darkest tones on the left and the brightest tones on the right. By analyzing the histogram, you can determine if the image is properly exposed or if it has any areas that are overexposed or underexposed. This information can help you make adjustments to the exposure settings to achieve the desired result.

Explanation
A vectorscope is used to check color levels. It is a tool that displays the color information of a video signal in a graphical form. It helps to analyze and adjust the color balance and chrominance levels of a video. By examining the position and length of the vectors on the display, one can determine if the colors are accurately reproduced or if there is any color imbalance or distortion in the video signal.

Explanation
The FS100 color profiles are labeled as "destructive" because they permanently alter the original color information of the image. This means that once a color profile is applied, it cannot be reversed or undone, leading to a loss of the original data. This can be useful in situations where a specific color effect or correction needs to be applied permanently, but it also means that any changes made cannot be easily reverted.
