Which of the following is NOT a common type of underwater camera housing?

  1. Compact Camera Housing

  2. DSLR Camera Housing

  3. Mirrorless Camera Housing

  4. Action Camera Housing

Show answer
Correct Option: D
Explanation:

Action cameras typically have their own waterproof housing, making a separate housing unnecessary.

What is the primary purpose of a strobe in underwater photography?

  1. To provide additional light for illuminating the subject

  2. To create a sense of depth and dimension in the image

  3. To reduce backscatter and improve water clarity

  4. To scare away marine life and prevent them from entering the frame

Show answer
Correct Option: A
Explanation:

Strobes are used to provide artificial light underwater, compensating for the lack of natural light and allowing photographers to capture well-exposed images.

Which of the following is a common technique used to minimize backscatter in underwater photography?

  1. Using a wide-angle lens

  2. Positioning the strobe close to the subject

  3. Shooting in manual mode and adjusting the shutter speed

  4. Using a snoot or diffuser on the strobe

Show answer
Correct Option: D
Explanation:

Snoots and diffusers help to focus the light from the strobe, reducing the amount of backscatter created by particles in the water.

When photographing coral reefs, what is the best way to avoid damaging the delicate ecosystem?

  1. Use a tripod to keep the camera steady and avoid touching the coral

  2. Wear gloves to protect the coral from your hands

  3. Avoid using strobes, as they can bleach the coral

  4. Move slowly and carefully, and avoid disturbing the marine life

Show answer
Correct Option: D
Explanation:

Touching or disturbing the coral can damage it, so it's important to move slowly and carefully while avoiding contact with the reef.

Which of the following is NOT a common type of underwater wreck?

  1. Sunken Ships

  2. Aircraft Wrecks

  3. Submarine Wrecks

  4. Natural Wrecks (e.g., fallen trees or rock formations)

Show answer
Correct Option: D
Explanation:

Natural wrecks are not typically found underwater, as they are more likely to decompose or be covered by sediment.

When photographing wrecks, what is the most important safety consideration?

  1. Checking the wreck's stability and condition before diving

  2. Using a dive computer to monitor depth and dive time

  3. Carrying a backup light source in case of equipment failure

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the listed safety considerations are important when photographing wrecks, as they help to minimize risks and ensure the safety of the photographer.

Which of the following is a common technique used to capture wide-angle images of caves?

  1. Using a fisheye lens

  2. Using a wide-angle lens with a dome port

  3. Using a telephoto lens with a long extension tube

  4. Using a macro lens for close-up shots of cave formations

Show answer
Correct Option: B
Explanation:

Wide-angle lenses with dome ports allow photographers to capture a wider field of view, making them ideal for capturing expansive cave interiors.

What is the primary challenge of cave photography?

  1. Limited visibility due to low light levels

  2. Strong currents and unpredictable water conditions

  3. Abundant marine life that can be distracting

  4. Risk of cave-ins and rockfalls

Show answer
Correct Option: A
Explanation:

Limited visibility due to low light levels is the primary challenge in cave photography, as it requires specialized lighting techniques and careful camera settings to capture well-exposed images.

Which of the following is NOT a common type of underwater photography lighting technique?

  1. Natural Light Photography

  2. Strobe Photography

  3. Continuous Light Photography

  4. High-Speed Photography

Show answer
Correct Option: D
Explanation:

High-Speed Photography is not a common lighting technique used in underwater photography, as it is more commonly used in other areas of photography, such as sports or wildlife photography.

What is the purpose of using a focus light in underwater photography?

  1. To illuminate the subject and improve focus accuracy

  2. To create a sense of depth and dimension in the image

  3. To reduce backscatter and improve water clarity

  4. To scare away marine life and prevent them from entering the frame

Show answer
Correct Option: A
Explanation:

Focus lights are used to provide additional light for illuminating the subject, making it easier for the camera to focus accurately, especially in low-light conditions.

Which of the following is NOT a common type of underwater photography composition?

  1. Wide-Angle Composition

  2. Macro Composition

  3. Portrait Composition

  4. Landscape Composition

Show answer
Correct Option: D
Explanation:

Landscape Composition is not a common type of underwater photography composition, as it is more commonly used in above-water photography to capture expansive landscapes.

What is the primary purpose of using a color correction filter in underwater photography?

  1. To adjust the color temperature of the water

  2. To reduce backscatter and improve water clarity

  3. To create a sense of depth and dimension in the image

  4. To scare away marine life and prevent them from entering the frame

Show answer
Correct Option: A
Explanation:

Color correction filters are used to adjust the color temperature of the water, compensating for the loss of certain colors (such as red) as light travels through water.

Which of the following is NOT a common type of underwater photography subject?

  1. Marine Life (e.g., fish, corals, sea turtles)

  2. Shipwrecks

  3. Underwater Caves

  4. Land-Based Objects (e.g., piers, bridges, buildings)

Show answer
Correct Option: D
Explanation:

Land-Based Objects are not commonly photographed underwater, as they are typically not found in underwater environments.

What is the primary purpose of using a buoyancy compensator device (BCD) in underwater photography?

  1. To control buoyancy and maintain neutral underwater trim

  2. To provide additional weight for sinking the camera

  3. To store underwater photography equipment

  4. To scare away marine life and prevent them from entering the frame

Show answer
Correct Option: A
Explanation:

The primary purpose of a BCD is to control buoyancy and maintain neutral underwater trim, allowing the photographer to move freely and capture images without sinking or floating uncontrollably.

Which of the following is NOT a common type of underwater photography accessory?

  1. Strobes

  2. Focus Lights

  3. Color Correction Filters

  4. Tripods

Show answer
Correct Option: D
Explanation:

Tripods are not commonly used in underwater photography, as they can be cumbersome and difficult to use in the water.
