High Speed Photography Reading Answers

Answer 27: C) too slow for human sight to detect
Supporting Sentence: For a matter of fact, the life cycle of a mushroom is relatively microscopic to the human eye.
Keyword: relatively microscopic to the human eye, life cycle of a mushroom
Keyword Location: Section B, 3rd line
Explanation: Time-lapse photographers can catch natural phenomena such as movements and events that happen too slowly for the human eye to see them. A mushroom's life cycle is quite minute, as you can see if you pay close attention.

Answer 28: A) occurs at a pace that is unperceivable
Supporting Sentence: Meanwhile, a hummingbird's wings flutter up to 80 times per second.
Keyword: subtle moments, wings flutter up to 80 times per second.
Keyword Location: Section C, 6th line
Explanation: In some senses, time-lapse photography and high-speed photography are diametrically opposed. While a hummingbird may flap its wings up to 80 times per second. The only way to truly record this action in its totality will be through the use of cameras that, in essence, slow down time.

Answer 29: D) vary the speed of the filming to keep it interesting
Supporting Sentence: The remedy is straightforward: simply adjust the playback speed, which is referred to as "film speed adjustment" by some.
Keyword: adjust the playback speed, film speed adjustment
Keyword Location: Section E, 7th line
Explanation: Biologists find the process through which a frog's tongue expands, latches onto its prey, and afterwards retracts to be interesting. However, this occurred 50 times more quickly than the speed of light. People immediately considered utilizing a high-speed camera to record this amazing movement in slow motion. But if you watch the frog swim in slow motion for too long, you'll get tired. The remedy is to change the film speed, also referred to as playback speed.

Answer 30: B) snap a picture at the location where the animal will pass.
Supporting Sentence: Photographers and filmmakers frequently position their cameras near bat caves, in the track of flying bats.
Keyword: near bat caves, position their cameras
Keyword Location: Section F, 3rd line
Explanation: Bats are very small, enigmatic, quick-flying animals that are only active at night. To capture photographs of bats on camera, a camera-tripping device must be used. To get the best shots of their subjects, photographers as well as filmmakers frequently position their equipment close to the bat cave and directly in the path of the flying bats. Even while incredibly advanced technical technology today makes automated photography possible, it can still take several nights to create a truly excellent piece of work.

Answer 31: lapse/time interval
Supporting Sentence: each frame is taken with a lapse at a time interval between each shot.
Keyword: lapse at a time interval
Keyword Location: Paragraph B
Explanation: The phrase "each frame is taken" in this question relates to the fact that photographers take photos at a lapse in time or before another photo.

Answer 32: continuous action
Supporting Sentence: each frame is taken with a lapse at a time interval between each shot when played back at normal speed, a continuous action is produced, and it appears to speed up.
Keyword: continuous action
Keyword Location: paragraph B
Explanation:When these photographs are exhibited in order, the narrator claims that the spectator witnesses a continuous motion.

Answer 33: Time
Supporting Sentence: put simply: we are shrinking time.
Keyword: shrinking time
Keyword Location: paragraph B
Explanation: The narrator mentions shortening time in this part of the inquiry.

Answer 34: greater length
Supporting Sentence: a greater length of the film is taken at a high sampling frequency or frame rate.
Keyword: greater length, high sampling frequency
Keyword Location: Paragraph C
Explanation: The narrator of the question mentions the film taking a high incidence rate here.

Answer 35: slowed down proportionally
Supporting Sentence: when replayed at normal speed, time appears to be slowed down proportionately.
Keyword: normal speed
Keyword Location: paragraph C
Explanation: Here, the narrator mentions that time has been slowed down to be proportional to the regular speed.

Answer 36. Section A
Supporting Sentences: Photography has been used by scientists to document and study movement, such as Eadweard Muybridge's 1887 study of human and animal locomotion. Keyword: human and animal locomotion
Keyword Location: Paragraph A
Explanation:  Eadweard Muybridge's 1887 study of animal and human mobility is one instance of how photography has been utilized by scientists to record and research movement in the past. At the same time, they experimented with different ways of representing reality, such as those promoted by the pictorialist movement.

Answer 37: Section C

Supporting Sentences: One of the countless applications is in biological studies, where it is used to analyse birds, bats, and even spider webs. While gorging on nectar, consider the motionlessness of a hummingbird floating almost stationary in the air.
Keyword: hummingbird floating
Keyword Location: paragraph C
Explanation: High-speed photography is used in biology to study bats, birds, and even spider webs. The hummingbird is motionless as it flies through the air, as though unaffected by the prey's flapping. Time-lapse cameras are the only way to truly capture this movement.

Answer 38: Section G
Supporting Sentences: It doesn't matter what the future holds for photography; the fact that "a picture is worth a thousand words" has been repeatedly shown in many facets of our lives & will ensure that the medium continues to evolve.
Keyword: photography, many facets
Keyword Location: paragraph G
Explanation: It has been consistently demonstrated in many parts of our lives that "a picture is worth a thousand words," and this will ensure that the medium continues to advance.

Answer 39: Section E
Supporting Sentences: However, during the post-production editing stage, this high frame rate will only be preserved for the prey-catching portion of it, while the swimming portion will be converted to the normal speed of 24 frames per second.
Keyword: post-production, swimming portion
Keyword Location: Paragraph E
Explanation: Only the quick frame rate for grabbing prey will be kept in the post-production (final edit), while swimming will be reduced down to a standard speed of 24 frames per second. The scientists may now relax and enjoy the show without worrying about the timing of the results.

Answer 40: Section F
Supporting Sentences: However, even while highly modern tripping devices can now allow for automated shooting, it may still take several nights to produce a truly high-quality piece of footage
Keyword: film shooting, human efforts
Keyword Location: paragraph F
Explanation: Photographers and filmmakers sometimes position their cameras close to the caves because they frequently use bats as a subject. The camera needs to have a tripping device in order to be activated if a bat passes the tripping beam and for it to function.
