What is the purpose of a transparency film in photopolymer printing?
-
To create a positive image
-
To create a negative image
-
To transfer the image to the printing plate
-
To protect the printing plate from UV light
A
Correct answer
Explanation
A transparency film is used to create a positive image on the photopolymer plate, which is then transferred to the printing surface.
What is the primary purpose of using a dolly in film production?
-
To create smooth camera movements
-
To adjust the camera's height
-
To change the camera's angle
-
To stabilize the camera during handheld shots
A
Correct answer
Explanation
Dollies are used to create smooth and controlled camera movements, such as tracking shots or panning shots, by allowing the camera to move along a track or surface.
What is the purpose of color grading in film production?
-
To adjust the color temperature of the film
-
To enhance the visual appeal of the film
-
To correct color errors
-
To create a specific mood or atmosphere
B
Correct answer
Explanation
Color grading is a post-production process where the colors of the film are manipulated to enhance the visual appeal, create a specific mood or atmosphere, and correct any color errors.
