Lenses and Filters


One of the best investments you can make as an underwater photographer is in quality lenses. Your lens selection becomes even more important because not all lenses are practical for underwater photography. We have limited the lenses in this section to only the ones that are appropriate to underwater use.

Filters are attachments that go over the front of the lens. They produce photo effects and help reduce certain issues by 'filtering' what the lens sees. With digital photo enhancement the way it is today, many people don’t believe they need filters. However, there are just some things you cannot change, even with a photo editor. Underwater the camera needs the addition of a red filter to help correct your images from being all blue or all green. Every diver has noticed that the underwater environment is one of the monochromatic hues rather than distinct colours. Depending on your location, objects will take on a blue or green cast at the expense of all things yellow, orange, red, etc. This is because water acts as a filter of red light. The deeper you dive the more the red spectrum is filtered from the ambient light. You can, however, emphasise the existing red light by filtering out the blue spectrum with a red filter of the right hue for the water type and depth.

PADI Wreck Diver

PADI Wreck Diver

Whether purpose-sunk as an artificial reef for scuba divers, or lost as the result of an accident, wrecks are fascinating windows to the past. Ships, airplanes and even cars are fascinating to explore and usually teem with aquatic life. Each wreck dive offers a chance for discovery, potentially unlocking a mystery or spying something others have missed. The PADI Wreck Diver Specialty course is popular because it offers rewarding adventures while observing responsible wreck diving practices.

What You'll Learn

Your training starts by reviewing guidelines for researching and respecting wrecks. You'll also learn:

  • Safety considerations for navigating and exploring wrecks.
  • Surveying and mapping a wreck.
  • Using penetration lines and reels to guide exploration.
  • Techniques to avoid kicking up silt or disturbing the wreck and its inhabitants.

Equipment

It's best to use your own scuba equipment, including a dive computer, plus a dive light to see the wreck, a slate and underwater compass for mapping and navigation. Your PADI Instructor can help you find the equipment that is appropriate for local wreck Diving.

Personal Equipment — You'll need to provide your own bathing suit and towel. For your personal hygiene and comfort, there are some things that we simply choose not to provide you with, and this is more out of concern for your health and well-being than anything else. These include:

  • Snorkel — Risk of orally transmitted diseases
  • Mask — To prevent masks fogging, divers spit in their masks. Would you like to put on your face something that someone else has recently spat in?
  • Gloves — Dermatitis
  • Dive Boots — Tinea is a nasty fungal bug that loves to jump from one person to another
  • Fins — Complete your own snorkelling kit

If you don't already have them, you can buy these items in our dive shop online or in-store. Our experienced dive shop staff can help you with the right equipment choices.

Rental Equipment — Rental gear is not included in the price. The Scuba Doctor has high-quality BCDs, Regulators with Dive Computers, Scuba Cylinders, Wetsuits and Weight Belts available for hire. See Scuba Equipment Rental for details.
