The delights of ice diving

Ice Diving

When most of us picture the perfect dive destination there is a tropical reef involved. There will be diverse marine life and lots of it, and maybe an interesting wreck or a two. The water will be warm and it won’t be far from a sunny beach where the drinks are cheap and the sand is just perfect for relaxing between sessions. However, there are some people with very different ideas about what makes up a great dive.
Ice diving is growing in popularity, slowly but surely. The attraction is rarely animal life, although very lucky individuals sometimes encounter seals and whales under and around ice. It’s more about the beauty of the ice itself or sometimes about the challenge. Pretty much anyone who can swim can do a basic Open Water course and learn to dive, but when there are icebergs floating around there’s an element of risk that can never be fully removed. In the event of an emergency, you can’t just surface anywhere.
PADI now certifies divers for icy water. The course covers things normal divers never have to consider- hole cutting, safety line placement, and, of course, how to deal with extreme cold. Full dry suits are the order of the day.
There is no shortage of places to try it. The waters off Ontario, Canada, are never all that warm, but in winter they’re becoming a favourite destination with ice divers. Russia’s Lake Baikal is the deepest lake in the world and an intriguing dive destination in summer, but the divers don’t go home when the ice comes. The chilly diving around Iceland can include underwater geothermal vents and other rarities, but the ultimate extreme cold diving experience has to be the North Pole.

Of course, diving under drift ice near the North Pole is not for everyone. For a start, most organizations require serious certification and a great deal of experience. It takes months of training and it’s not cheap either, but plenty of divers still feel the call and end up diving in some of the coldest, strangest waters on Earth.

Scuba divers- look after your ears!

July 14, 2011 in Scuba Diving Tips

Most divers experience some kind of ear pain occasionally, and in the vast majority of cases it's just temporary and goes away when you equalize. Once there isn't such a pressure difference between the middle ear and the outer, there's no problem. However, the middle ear is delicate, and damaging it can end a diving career faster than almost everything else. Here are a few guidelines to help you take care of your ears:
  • Equalize early and often, before ‘ear squeeze’ becomes ear pain.Diving
  • If for any reason you can’t equalize, don’t go any deeper. Come back up a little and try again. If you still can’t do it, abort the dive and go back another day. Keep going and you could do permanent damage and even rupture the ear drum.
  • Got a cold? An itchy feeling inside the ear can be the first sign of an ear infection. Anti-inflammatories like ibuprofen can help, but if it persists, see a doctor quickly. Ear infections can become very painful quite fast, and if left untreated they can really hurt your future diving plans too.
  • If you have got a cold or you’re experiencing hay-fever troubles, stay out of the water. Sinus problems can prevent you from equalizing properly and coughs and colds bring with them a greater risk of underwater breathing difficulties.
  • When you’re back on the surface, avoid clearing water out of your ears with cotton swabs. This can contribute to conditions like swimmer’s ear- an infection of the outer canal.
  • Be careful around air valves. If you’re going to open the valve on a full tank without regs attached, go slow and make sure it’s nowhere near your ears. A sudden burst of high-pressure air can easily damage an ear drum.
  • A little ear-wax is healthy and will protect your ears from irritation. Unless you have so much it’s causing medical problems, leave it be and it’ll look after you.

How to take care of your underwater camera

June 20, 2011 in Maintenance

It is undeniable that the underwater world is a beautiful place. Back in the day people would just marvel the beauty of the underwater scenes. Looking at it first hand to capture in memory. Nowadays however, due to the availability of underwater cameras, beautiful scenes can already be captured at our own will with just one click.

An underwater camera is just like any other posession that you should maintain and take care of properly for it to last for a long time. We must also remember that underwater conditions are very different, compared to conditions that we have on land. Thats why we should take extra care of our underwater cameras.

Some important tips that may prove helpful…

Watch the pressure
The water can be so inviting that we forget to think about our cameras when we plunge into the water with a camera at hand. This can harm your camera as splashes may penetrate through the O rings of your device. The best way to take care of your equipment is not to dive with it. Let someone give it to you after you take the plunge or go in feet first if there is no one to hand it to you.

Check for leaks
For those cameras which are made with a waterproof casing, please always check for leaks before going in the water to prevent your camera from being damaged by unwanted water.

Rinse… Rinse… Rinse!
Always make it a habit to rinse your underwater camera after every shoot. You can do this by leaving your camera soaked in freshwater for a set of hours. Not only that you also have to make sure that you turn knobs often to remove residues of salt or sand which may have stuck up in some parts of your camera during your shoot. When you plan to open your camera, make sure that your unit is dried up or water might touch the camera and its inner parts and you may lose good shots in the end.

Check your O rings
O rings are those rings which help your camera to be dry underwater by preventing water to come into the unit. Make sure that it is clean of sand and other particles which may ruin the function of the rings.

Know how to troubleshoot
There may be times that you may encounter issues with your underwater camera. There are usually basic troubleshooting tips in your manual. This is true for most of the underwater cameras in the market today. It is better to deal with the problem yourself than to wait until the next day and lose the opportunity to take a good shot.
An underwater camera is the portal to a whole new experience in photography. There are a lot of scenes that are exclusive to the underwater world alone so it would be best to have a camera at hand to capture the beauty that it shares. Your underwater camera will last for a long time as long as it is well taken care of. This will not only make you get good shots but maximize you experience as well.

Underwater Photography Tip: Capture the Eyes

June 16, 2011 in Underwater Photography Tips

Are you disappointed that your underwater photography seems to lack the magic you felt during the actual dive? Underwater photographs seldom convey the connection you felt with the aquatic life around you. By simply trying to focus on the eyes of the fish and creatures you encounter, you’ll begin to come away with some amazing photographs that better convey the experience of snorkeling or scuba diving. This is easier said than done, but here are some helpful tips to get you started.

The first thing you should do is practice swimming in a way that fish will feel less threatened by. Fish won’t want to be anywhere near you if you’re constantly flailing your arms and legs about. Practice floating, and use the smallest, slowest motions to remain in place.

Once you can do that, concentrate on your breathing. Breathe in and out slowly and steadily so you won’t have huge periodic bursts of bubbles that send fish scattering in all directions. Otherwise, you’ll continue to have lots of photographs of beautiful tail fins as they swim away from you. With patience and practice you will master the ability to drift smoothly along on the current without making excess movements, and the fish will allow you to move in closer.

Next, take some practice shots of an immovable object, such as an anchor or some coral. Immediately compare the photos with what you’re seeing through your goggles. Several factors will cause you to distort distances underwater, including your goggles, the housing on your camera, and the water itself. In general, when shooting underwater, what appears to be about one foot away from you is actually 1.3 feet away. Continue to experiment with your camera until the photographs are coming out the way you expect them to.

Now it’s time to find some fish. Clearly capturing the eye of your subject is essential in any type of wildlife photography, because it is through the eyes that we establish the strongest sense of connection with that creature. It’s even more important to master this technique for the situations when you cannot fit the entire animal in your viewfinder. If you can clearly catch an animal or fish’s eyes in your photographs, you’re almost guaranteed to come away with a memorable photograph.

From: Monterey Bay Aquarium

Instead of chasing after a group of fish, notice where they’re congregating and swim to that area. Move in as close as possible without touching any natural coral formations. Simply touching coral can kill off large portions of this beautiful natural habitat. Find a good place to photograph from, then use the techniques you learned above to stay in place. It takes patience, but the fish will come back, and you will end up with much better photographs of fish swimming towards you than you would have chasing them down.

In order to capture their eyes clearly, you’ll need to keep the camera as still as possible. If the camera is moving as you’re drifting through the water, your photographs will come out blurry. Taken by Mozaik Underwater CamerasProp your elbow against your chest to help steady the camera while you focus in on the creature’s face. Try to photograph at eye level, or from underneath your subject for a more dramatic effect. Shooting at a downward angle poses two problems. First, you’re likely to have a lot of sand or seaweed in the photographs, which will draw attention away from your subjects. Second, the picture will come out darker than if you are shooting upwards towards the water’s surface. When you’re shooting at eye level or lower, your photographs will tend to come out more clearly and with better light quality.

Keep clicking and take lots of pictures – you can always delete the ones you don’t like later. The more you practice, the more you’ll learn, and your trigger finger will become steadier with time. With patience and a steady hand, you’ll soon be bringing back some amazing images that portray the beautiful lives of the underwater creatures you encountered.

Custom White Balance Underwater

June 14, 2011 in Underwater Photography Tips

Underwater photography differs from standard photography in many things, one of the most significant changes is the white balance.

Auto White Balance

Auto White Balance - Very Blue-ish

The water acts as a blue filter therefore chaging completely the natural color balance that we know above water. Most of todays digital cameras are not equipped with an underwater mode and are designed in software to adjust to white balanced that are common in our everyday life.

For the above reason , the auto white balance feature usually works poorly underwater and does not adjust the colors correctly to compensate on the strong effect of the blue or green water.

When choosing a camera to take underwater , it is very important to make sure it has a manual white balance mode , this mode will come in handy in almost every dive and will save you the hassle of going through photoshop for every photo taken.

The process differs between cameras but the general idea is to take a white or gray card (one that does not have a hue and is nuetrally balanced) , goto the cameras white balance setting and choose manual. You will then need to point the camer and the card and push the shutter button or a different button and the camera will determine the compensation it needs to do for this card to actually be neutral.

When diving , it is usually recommended to go through this process every 20 feet or so..

Underwater Photography Tips

May 23, 2011 in Guides and Tips

The page is dedicated to underwater photography and videography tips. We will include tips from our experience and ones we received from our customers covering all aspects of underwater photography.

  1. Do not rely on auto white balance , use manual white balance if possible or use an external light source such as a strobe or video light.
  2. When using a strobe or Video light , use auto white balance or set it to 5500-6500 color temperature.
  3. When using a strobe , do not point the strobe at the same angle as the cameras lens to avoid back scatter. Keep the strobe as far as possible from the housing.
  4. Take EV compensation down a notch for emphasizing blue water color and getting faster shutter speed.
  5. Use a wide angle lens when shooting wrecks to present a much stronger effect of the scene.
  6. Get as close as you can to the subject to reduce to minimum the color fading from the water.
  7. Use built in flash in manual to force the flash to fire and enhance the colors of the object. Make sure your photos are not over compensated by the flash.
  8. Secure the housing to your BCD or hand with a cable.
  9. Put silica gel packs inside the housing to absorb humidity and prevent fog on the port.
  10. Wash you housing with fresh water after every dive.
  11. Shoot come videos every now and then, you’ll appreciate it when you try.
  12. Sometimes , adding a strobe can improve your photos more than upgrading your camera.
  13. Learn some photoshop post processing skills , even a few basic settings can improve your photos significantly.
  14. Use ambient light and turn off the flash in shallow water on a sunny day ( up to 15 feet ) , the sun will create beautiful colors and shades to your photos. Try to put the sun at your back while shooting.
