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.

Reef Dive | Boat access
Depth: 3 m (9.84 ft) to 13 m (43 ft)
Level: Open Water and beyond.
Nargra Reef lies offshore from Keillers Beach Road, east of Portland, in Portland Bay (aka Henty Bay) on Victoria's Discovery Coast. It's a limestone reef that has been eroded by the swell into a series of gutters and overhangs.
Nudibranchs and gorgonian corals adorn the ledges along with a variety of fish species. The area is also noted for the fossilised Giant White Pointer Shark Characharadon Megalodon teeth that are occasionally found here.
This area is frequented by boats, so please make sure you display your dive flag in this area.
Nargra Reef is accessed by boat from the Portland Harbour, Lee Breakwater Road North Ramp or the Portland Harbour, Lee Breakwater Road South Ramp.
Best dived in good conditions with a low swell with light north or northerly winds. See WillyWeather (Portland North) as a guide for the tide times and the height of the tide.
{{southern-ocean-warning}}Traditional Owners — This dive site is in the traditional Country of the Gunditjmara people of far south-western Victoria which continues over the state border into a small part of south-east South Australia and is bordered by the Glenelg River to the west and the Wannon River in the north. This truly ancient Country extends 100 metres out to sea from low tide and also includes Deen Maar (aka Lady Julia Percy Island) where the Gunditjmara believe the spirits of their dead travel to wait to be reborn. We wish to acknowledge the Gunditjmara as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.
The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
