PADI Photography & Videography Underwater 2

Question 1

Why do underwater photos often appear blue-green even when taken at shallow depths?

Accepted Answer

Water selectively absorbs red and orange wavelengths first

Answer

Water absorbs red wavelengths within the first few feet of depth, progressively removing warm colors and leaving blue-green hues dominant.

Question 2

What is the primary advantage of shooting in RAW format for underwater photography?

Accepted Answer

Post-processing allows extensive white balance and color correction

Answer

RAW files retain all sensor data, allowing photographers to correct white balance and recover color information lost to water absorption in post-processing.

Question 3

When filming a wide-angle scene of a coral reef, the videographer notices strong backscatter in the footage. What is the most effective solution?

Accepted Answer

Move video lights to the side and angled away from the lens axis

Answer

Positioning lights at a wide angle away from the lens axis prevents illuminating suspended particles directly in the camera's field of view, minimizing backscatter.

Question 4

A diver wants to photograph a shy moray eel retreating into a crevice. Which approach best demonstrates good underwater photography etiquette?

Accepted Answer

Use a long macro lens and remain at a respectful distance

Answer

Using a long macro lens allows close-up shots while maintaining distance from the subject, minimizing disturbance to marine life.

Question 5

What does the term 'depth of field' mean in underwater photography?

Accepted Answer

The range of distances in a scene that appear acceptably sharp

Answer

Depth of field is the zone of acceptable sharpness in an image, from the nearest to the farthest point that appears in focus.
