What is the purpose of panning in sports photography?
-
To create a sense of motion blur
-
To emphasize the speed and movement of athletes
-
To isolate the subject from the background
-
To create a dramatic effect
B
Correct answer
Explanation
Panning is a technique used in sports photography to emphasize the speed and movement of athletes by blurring the background while keeping the subject sharp.
What is the primary purpose of a fragment shader in a real-time graphics pipeline?
-
To transform vertices from model space to world space
-
To apply lighting and shading calculations
-
To generate texture coordinates
-
To perform rasterization
B
Correct answer
Explanation
The fragment shader is responsible for applying lighting and shading calculations to each pixel in a fragment, determining the final color.
What is the primary purpose of a texture in real-time graphics?
-
To store color information for pixels
-
To store depth information for objects
-
To store normal information for surfaces
-
To store specular information for highlights
A
Correct answer
Explanation
Textures are used to store color information for pixels, providing surface details and patterns.
What is the primary purpose of a normal map in real-time graphics?
-
To store color information for pixels
-
To store depth information for objects
-
To store normal information for surfaces
-
To store specular information for highlights
C
Correct answer
Explanation
Normal maps are used to store normal information for surfaces, providing detailed surface features and shading.
What is the primary purpose of an animation system in real-time graphics?
-
To create and manipulate skeletal animations
-
To handle user input and game logic
-
To generate lighting and shading effects
-
To perform collision detection
A
Correct answer
Explanation
Animation systems are used to create and manipulate skeletal animations, allowing characters and objects to move realistically.
What is the primary purpose of using a reflector in photography?
-
To reduce the amount of light falling on the subject
-
To increase the amount of light falling on the subject
-
To change the color of the light falling on the subject
-
To soften the light falling on the subject
B
Correct answer
Explanation
A reflector is used to bounce light back onto the subject, increasing the amount of light available for the exposure.
What is the main function of a diffuser in photography?
-
To reduce the amount of light falling on the subject
-
To increase the amount of light falling on the subject
-
To change the color of the light falling on the subject
-
To soften the light falling on the subject
D
Correct answer
Explanation
A diffuser is used to spread out the light from a light source, making it softer and less harsh.
What is the primary purpose of using a scrim in photography?
-
To reduce the amount of light falling on the subject
-
To increase the amount of light falling on the subject
-
To change the color of the light falling on the subject
-
To soften the light falling on the subject
A
Correct answer
Explanation
Scrims are used to reduce the amount of light falling on the subject, creating a softer, more diffused look.
In signal processing, what is the purpose of zero-phase filtering?
-
To eliminate phase distortion in a signal.
-
To preserve the temporal relationships between signal components.
-
To enhance the signal-to-noise ratio.
-
None of the above.
A
Correct answer
Explanation
Zero-phase filtering aims to eliminate phase distortion in a signal. It ensures that all frequency components of the signal experience the same delay, preserving the temporal relationships between them.
What is the purpose of using leading lines in drone photography?
-
To create a sense of depth and perspective
-
To draw the viewer's eye to the subject
-
To create a sense of balance and symmetry
-
To add interest and variety to the image
B
Correct answer
Explanation
Leading lines are used in drone photography to draw the viewer's eye to the subject of the image. They can be natural features, such as roads, rivers, or coastlines, or man-made structures, such as bridges or buildings.
What is the purpose of using a neutral density (ND) filter in drone photography?
-
To reduce the amount of light entering the camera
-
To increase the amount of light entering the camera
-
To change the color temperature of the light
-
