Underwater Digital Cameras
by: Jakob Jelling
Underwater photography's is primarily focused towards entertaining and informing the people and the users themselves about what is happening in the world of under water with the aid of photography. The advent of digital cameras has opened up new horizons for such ventures. These digital cameras are not only handy and sleek but also they offer a spectral range of features that helps the underwater photographers in their work a lot. In this discussion these special features of underwater digital cameras are necessarily been revealed and done justice to!
Looking at the grass root level some of the main features that the users of the underwater digital cameras must necessarily seek are as follows. They are applications for land mode, sea mode and external flash mode. This helps in shooting in any conditions in the sea and obtains much better picture quality than ever before. Some other features are like instant delete option after each picture in both sea and external flash modes along with one-button operation features. These mentioned features provide the sophistication as well as ease of control for the photographers. Some more desirable features are expandable and good quality standard lenses, flashes and accessories.
Some of the sophisticated and well know underwater digital cameras such as the Aqua Pix DX3100 are fully functional and even have a 3.1 mega pixel resolution. These digital cameras can be aptly described as being effusively amphibious! Thus the chances of water damage and flooding in these underwater digital cameras are greatly reduced and are hence extensively used for professional purposes too.
Scrutinizing in some more detail it can be said that the underwater digital cameras mostly use a meniscus lens that can be used above or below the surface of water. The also have features for built in color correction filter and macro lens along with built in flash diffusers too. They utilize multi flash functioning in order to get adequate good quality pictures in the most adverse conditions too. They have sufficient memory of around 15MB and come equipped with complete storage, editing and image manipulation software.
It still remains a fact that underwater photography is a difficult yet fascinating profession. Moreover, with the underwater digital cameras this task has become even easier and creative along with greater scopes to express much more through the eyes of the lens. It is hoped that the new depths of underwater photography would be fathomed with the aid of the underwater digital cameras!

Underwater Photography: The Wonders Under the Sea
Underwater Photography: The Wonders Under the Sea
by: Colin Hartness
The world of photography is an amazing one. It’s been with us for quite a while now but it is constantly changing. Cameras are changing and improving. Methods of developing are changing and improving as well. We have digital cameras that allow people to take a view of their pictures immediately without traditional developing. Another change in the world of photography is underwater photography.
What do you think brings us those great shots of saltwater fish and movies that film in the ocean and under the sea? What about shots taken in swimming pools? You see those in the movies a lot but may not have thought about how they take those pictures and videos.
You probably never thought about it because for a long time underwater photography was not really an option for everyday people. But now it is not just an option, it’s really easy to achieve.
- What is Underwater Photography?
Underwater photography is as the name implies photos that are taken under water. This is pretty interesting since early cameras could not function if wet. But as people started discovering the wonders under the sea, they wanted to be able to share that with others or even just to prove what they actuallysaw. So we began creating cameras that could work under water.
It is no surprise that underwater photography is a favorite pastime for scuba divers. The idea could have come from those few people that were able to experience the joys and beauty of underwater life and a desire to share that beauty with others.
There are many different occasions where people use underwater photography. As we mentioned earlier, underwater photography is used in Hollywood for movies. You have probably also seen it used on documentaries and national geographic type programs about underwater life.
But it is still most commonly used by divers. There are many websites dedicated to all the ins and outs of underwater photography; which cameras and lenses are best, which film to use, and much more can be found on these sites.
- How to Take Underwater Photography
Equipment is an important factor in taking great underwater photography. Of course you will need an underwater camera but there is more than just that.
You can take some amazing pictures using underwater photography. There are now even disposable use underwater cameras and you can take them on vacation with you and get that great underwater look. Even an amateur can do it. Disposable underwater cameras can typically be developed at your local Wal-Mart or other film developing center. You can also purchase underwater cameras for more of a price but they last whenever you need one. Some people find this more economical than disposables, especially if they want to take these pictures often.
Just like other venues of photography, you will probably start off with a cheaper and less advanced camera and work your way up if you continue underwater photography for a long time. There are two basics kinds of cameras; the underwater or waterproof camera and the encased camera which is inside a housing that protects it.
When taking pictures, you are going to need to be familiar with:
* Your camera
* Your lens
* Your film
* Your flash
There are different things in your environment that will affect the quality of your underwater photography.
Such as:
* Depth of water and transparency of water
* Light
* The angle of the sunlight on the top of the water
* The backscatter
* Water has a magnifying effect
These are some things to help you get started in the world of underwater photography. If you are lucky enough to be swimming in the sea, you should get some proof to share with others.

Trout Fishing Guide
Trout Fishing Guide
by: Soh Suad Hun
Trouts can be found in many freshwater streams, lakes and rivers across the globe, particularly in the United States, Canada, Europe and New Zealand.
As a fisherman, it is important that you always consider what type of trout you are after and their feeding habits to better understand and plan your approach.
There are three very popular types of trout:
• Speckled trout (brook trout)
• Rainbow trout
• Brown trout
The species and type will depend on where you are fishing at and what part of the world you are in.
Brook trout (speckled trout) thrive in smaller streams of good water quality, in pools of water more shallow than where you typically find other types of trout. They are smaller in size than other trouts but can be very aggressive.
Rainbow trout are typically native to the west coast of USA but due to stocking, they are found in many other areas as well. They occupy large water of streams and rivers and have different habitats than the other two types. They are famous for their "tail-walking" which is similar to water acrobats and is quite exciting for many fishermen to watch.
The Brown trout is larger in size compared to the Brook trout and the Rainbow trout. It is found in abundance in many areas of Europe and USA. This type of trout are usually more difficult to catch as they are wary of fishing lures and bait and not aggressive as the brook trout. More patience are required when fishing for brown trout. They are usually found in deeper pools of water and most often feed early in the morning or late in the afternoon.
Before you set off for your trout fishing trip, do you homework. Find out as much about the area/ streams/rivers that you will be fishing on. Are there many fishermen fishing there too? What's the temperature and climate? Is the area a public or government owned that has regulations? Go on the internet and join a forum so you can ask around people who have fished there before.
The more you know about the area and the fish that you plan to catch, they more successful you will be in your trout fishing attempts.

Underwater Photography - Just a Hobby or is there a Serious Side?
Underwater Photography - Just a Hobby or is there a Serious Side?
by: Sandi Faist
When we think of underwater cameras and photography, we think of capturing what we see while snorkeling and diving; we think about the pictures we’ll take and share. We practice taking better and better pictures; it’s a hobby and we love it. Or we share them with people not lucky enough to have seen the beauty of what lies beneath the seas and oceans. The fish whose colors we’ve only seen in saltwater tanks. We think about good things; vacations and relaxation, adventure and exotic creatures.
But there are other uses for underwater cameras that don’t paint such a pleasant picture. Unfortunately, I was reminded of this recently when two young children disappeared after wandering off. Their home was by a river. I’m sure they’d been told of the dangers of the water, to not go near it without an adult. But the draw may have been too much. The river was running high as there had been recent storms.
Search and rescue operations use underwater photography to search for drowning victims as well as missing objects. Of course, the recovery of drowning victims as quickly as possible to bring closure to families suffering from the loss of a loved one is the primary purpose. These searches typically have been done using divers and water-trained dogs. However; underwater searches can be very treacherous to the divers, and are time consuming. Another problem being that many times it is unknown where the victim was last seen, broadening the search to a vast area, often to hundreds of acres.
Underwater cameras enable law enforcement to see water crime scenes in areas too dangerous for divers, and without disturbing the site. Investigations with video tapes may be used to determine whether or not there actually is an underwater crime scene. Rather than send divers in to dangerous waters, cameras can be used to search in polluted and hazmat areas. There are underwater cameras designed to search at depths of up to 120 feet in most water conditions. Infra-red systems allow for searches in low light situations.
Amazingly, divers have used video photography to locate objects that have been missing for several years or more. A missing persons’ case was solved after 72 years when a couple’s car was found, putting to rest what had happened to them, and bringing closure to their family. Not to mention the unfortunate rumors that they had left their children voluntarily.
Besides simple pleasure and law enforcement, underwater photography is used in many other ways. Marine biologists can locate fish and living marine animals to study their habitats. On a boat, cameras can check the anchor and hull and look for items that have fallen overboard. Pools can be monitored. Swimmers can be filmed under water to evaluate their swimming and diving techniques.
In sport fishing, underwater photography is used to identify actual fish from underwater debris, decreasing fishing time. You can check what type of fish is in your location; see that your lure doesn’t become entangled in weeds; check the hull; and check crab or lobster pots without getting wet. The cameras can even be used for ice fishing.
Not only are these remarkable cameras and their technology an exciting hobby, they have numerous other valuable applications.

Career In Scuba Diving: Your Future Being A Dive Instructor
Career In Scuba Diving: Your Future Being A Dive Instructor
by: Clive Jenkins
Scuba Divers are made of many people that are tired of the usual tedious workday, followed by the nerve-racking task of driving; add all the noise pollution it instigates. That's before everything else scuba divers encounter in these fast paced times outside of scuba diving.
Some scuba divers go even further by finding a career in scuba diving. Some become diving instructors themselves. They find their career in scuba diving rejuvenating compared to many other choices.
Scuba diving doesn't usually start there though. It usually starts where many other's scuba diving began; with the open water course. Then they move onto the advanced course and learn much more and realize they really enjoy all that scuba diving has to offer. They see diving underwater in a whole new way, and really want to share that with others as well. Often this leads them to work towards a career in scuba diving instruction.
It's not all simple courses and then going to work with your new career in scuba diving. You need to be a master at it. This of course means a lot of diving time in a variety of situations and an instructor or more. You need to know how to dive and survive well. With that, as a scuba diving instructor you will be able to bring others up to scuba diving. You need to know what they have to, to dive safely. This is quite a worthy career!
Many look up to the diving instructor assuming they know it all about scuba diving. Since the potential to inspire them can be great or potentially heartbreaking, you really do need to know anything they need to know, and more! When you don't, you need to admit that as well! If your journey is endlessly learning more when diving in many situations, you should seriously consider a career in scuba diving as an instructor.
Though also consider that you need to deal with people, and follow timelines. You need to be able to teach your students in a short time, how to remain safe and alive when scuba diving. This is quite a responsibility. If you feel this is for you, it's time we look further towards your career in scuba diving instruction.
To become a diving instructor you must first be a Dive master. With that out of the way, then you have to take the Instructor Development Course (PADI IDC). This extensive course will take you deeper into diving than you have been. It will educate you on diving standards, safety, students, the PADI system, and relevant law. To be all you can be you will definitely want to master every bit of it. That way when you begin your career in scuba diving instruction, you will be well versed from the start. Of course beyond that, experience will follow that will truly make you a complete export in your craft.
As with anything these days, while working on your career in scuba diving, you can expect much product marketing information, as well as sales literature too. While it's not wise to buy everything, you should understand the market, as it does affect your students as well.

How To Choose The Right Scuba Fins
How To Choose The Right Scuba Fins
by: Laura Cain
When it comes to investing in your own pair of scuba fins, you have a plethora of choices from a number of manufacturers who continue to advance the engineering they use to produce the most durable, efficient fins possible. While the original, traditional full foot scuba fins are still popular among some people, there are many more styles available now. Most of the new styles of scuba fins are designed by using technical and involved mathematical angles and engineering so that the fin works to the divers advantage as far as efficiency and ease of use.
Some people find themselves being turned off by the complex and technical features of these efficiently advanced scuba fins, leaving them to be content with basic, traditional fins, which is not a bad thing. The main point to remember when purchasing your own scuba fins is comfort. If you are uncomfortable or awkward in a pair of fins, they aren't going to work for you as intended. The specialized angles or split fins used to create greater kicking efficiency are only effective if you are comfortable wearing the fin and using it in the water. Comfort is important because only when you are fully satisfied with you fins will you be able to use them properly.
To help you choose which type of scuba fins will work best for your intended use you should research each style. First are the traditional paddle fins. Paddle scuba fins can be either full foot or have an adjustable heel strap. For scuba diving purposes, people most often use the adjustable heel strap fins of any style. Full foot fins are commonly used as snorkeling fins. Traditional paddle fins work to move water up and down as you kick and they are complimented by divers as being useful when free diving or in currents.
Several major scuba equipment companies have released a new, specially engineered paddle fin that provides much more move for you kick. Dacor and Tusa both have scuba fins with the optimized pivoting blade which is a design that angles the fin so every time you are kicking upward or downward the fins are at the most efficient angle for getting a more forceful kick. The specialized angles of these scuba fins alter the angle traditional paddle fins have, which makes you loose full force during part of the kick.
The next type of scuba fins are all altered in some way with splits, cutouts or vents that the manufacturers say enhance the kicking force and efficiency. The most prevalent of these are the split fins, also known as "Bio-fins" by some companies. These scuba fins divide the paddle of the fin into two parts with a sliver taken out of the middle vertically. Many people have come to appreciate the efficiency and forceful strokes split fins have been proven to allow you. The modification to these fins is supposed to minimize the number of kicks needed to get a set distance. Some divers still believe the most capable scuba fins are the basic ones. Again, the fins you choose should be primarily based on comfort and how easily you function in them.
Other types of split fins have horizontal splits or cutouts and vents at strategic places on the paddle. The Apollo Bio-fins are split scuba fins engineered to push water back, as opposed to up and down, like most fins. The Bio-fin acts like a propeller instead of a paddle, allowing you a much easier kicking task.
Force fins are an additional style you have to choose from. This type of scuba fins is considerably smaller than others, but if you are comfortable using them, they can provide equal kicking force. Force fins mimic a small scale whale tail, which is part of the reason they are claimed to have successful kicking efficiency.
Choosing between these broad types of scuba fins is only the beginning. Within each type there are several other designs to pick from and choosing which brand can be difficult too. Most people limit their selection by having a budget or price range not to exceed. Limiting yourself to a budget will not spoil a large selection though, because there is a variety of scuba fins in every price range. Obviously, the basic and simple scuba fin designs will be the least expensive and as the fins advance in efficiency technology and specialized features, the price will rise.
If you are an avid diver, owning pair of durable and efficient scuba fins is a must, so it would be wise to spend a little extra money on fins with some of the advanced features. At asudoit.com there equipment sold for many adventure sports, including several brands and styles of scuba fins. Here you can look through the features of all the broad types of scuba fins such as force, split, full-foot, heel strap and traditional paddle fins. DiversDiscount.com also has a large selection of scuba fins of all types. At this site you pay less than half the original price for the Tusa Platina fins, which have dual blade fins for greater propulsion force. These Tusa scuba fins are high-performance and available at a cheap price at the discount site.
As for shopping by specific brands, you may want to start with the most commonly know names in scuba equipment such as Apollo, Dacor, Oceanic, Sherwood and Tusa. Some scuba equipment companies are conglomerates, which means some of the less known and less expensive brand names you see may actually be made by one of the larger companies. This is a plus for you because often the branch off brand equipment will be cheaper price wise, but with quality and durability nearly equal to that of the more expensive, better known brands. Each of these manufacturers will have scuba fins for all types. Brand name preference is a personal choice, but each of the above brands are well known, reliable names in scuba fins.
Choosing scuba fins is a matter that is based on personal preference and each individual's selection will be different, but none of them are wrong. Because of this, it is helpful to have the wide selection available so that everyone's preferences are accommodated. Whatever your choice, know that you are comfortable in the fins before you purchase them and look in to the quality and durability of the fins, as it will determine the fins life span and help you decide if they are worth the money.

The specialized angles of these scuba fins alter the angle traditional paddle fins have, which makes you loose full force during part of the kick.
The next type of scuba fins are all altered in some way with splits, cutouts or vents that the manufacturers say enhance the kicking force and efficiency. The most prevalent of these are the split fins, also known as "Bio-fins" by some companies. These scuba fins divide the paddle of the fin into two parts with a sliver taken out of the middle vertically. Many people have come to appreciate the efficiency and forceful strokes split fins have been proven to allow you. The modification to these fins is supposed to minimize the number of kicks needed to get a set distance. Some divers still believe the most capable scuba fins are the basic ones. Again, the fins you choose should be primarily based on comfort and how easily you function in them.
Other types of split fins have horizontal splits or cutouts and vents at strategic places on the paddle. The Apollo Bio-fins are split scuba fins engineered to push water back, as opposed to up and down, like most fins. The Bio-fin acts like a propeller instead of a paddle, allowing you a much easier kicking task.
Force fins are an additional style you have to choose from. This type of scuba fins is considerably smaller than others, but if you are comfortable using them, they can provide equal kicking force. Force fins mimic a small scale whale tail, which is part of the reason they are claimed to have successful kicking efficiency.
Choosing between these broad types of scuba fins is only the beginning. Within each type there are several other designs to pick from and choosing which brand can be difficult too. Most people limit their selection by having a budget or price range not to exceed. Limiting yourself to a budget will not spoil a large selection though, because there is a variety of scuba fins in every price range. Obviously, the basic and simple scuba fin designs will be the least expensive and as the fins advance in efficiency technology and specialized features, the price will rise.
If you are an avid diver, owning pair of durable and efficient scuba fins is a must, so it would be wise to spend a little extra money on fins with some of the advanced features. At asudoit.com there equipment sold for many adventure sports, including several brands and styles of scuba fins. Here you can look through the features of all the broad types of scuba fins such as force, split, full-foot, heel strap and traditional paddle fins. DiversDiscount.com also has a large selection of scuba fins of all types. At this site you pay less than half the original price for the Tusa Platina fins, which have dual blade fins for greater propulsion force. These Tusa scuba fins are high-performance and available at a cheap price at the discount site.
As for shopping by specific brands, you may want to start with the most commonly know names in scuba equipment such as Apollo, Dacor, Oceanic, Sherwood and Tusa. Some scuba equipment companies are conglomerates, which means some of the less known and less expensive brand names you see may actually be made by one of the larger companies. This is a plus for you because often the branch off brand equipment will be cheaper price wise, but with quality and durability nearly equal to that of the more expensive, better known brands. Each of these manufacturers will have scuba fins for all types. Brand name preference is a personal choice, but each of the above brands are well known, reliable names in scuba fins.
Choosing scuba fins is a matter that is based on personal preference and each individual's selection will be different, but none of them are wrong. Because of this, it is helpful to have the wide selection available so that everyone's preferences are accommodated. Whatever your choice, know that you are comfortable in the fins before you purchase them and look in to the quality and durability of the fins, as it will determine the fins life span and help you decide if they are worth the money.

How Do Underwater Cameras Work?
How Do Underwater Cameras Work?
by: Nicola Kennedy
Underwater Cameras are cameras that are specially designed for underwater use or in circumstances that requires protection to prevent any water and pressure damage. There are many types of underwater cameras, depending on your budget and uses.
There are underwater cameras that are simply disposed of after use. These are the cheapest type of underwater camera available in the market. They have the capacity to take between 20 to 30 pictures, and photos can easily be developed. They are waterproof enough to be used in harsh rain and snow storms, and are usually tolerant of being fully submerged up to twenty or thirty feet.
There are also underwater cameras that are cheap reloadables. These cameras are designed with economy of price in mind. These are very similar to disposable underwater cameras, expect that the user can replace the film and use the camera multiple times. They are usually capable of greater water depths than their disposable counterparts.
New generation cameras have resolutions in the 3-4 megapixel range and can take excellent quality pictures underwater.
These cameras offer options for every level of diver and snorkeler. For the experienced diver/photographer who wants more control over the camera functions. The Advanced-Dive control system allows users to manipulate resolution, light sensitivity (EV), exposure modes and much more while underwaterwhile the Easy-Dive control system is the perfect choice for divers seeking a simple underwater photo system that produces breathtaking results.
Underwater cameras are designed for one-Button-Operation and can be set to Land or Sea modes plus modes that take into account the unique aspects of underwater photography. Cameras also feature three dedicated underwater external flash modes, allowing for more exposure control when using an external flash. For perfectly lit photos in any situation, users can toggle among Macro Flash, Portrait Flash and Far Flash modes, which adjust exposure based on camera-to-subject distance.
While an on-camera flash helps illuminate objects below the surface, cameras are also compatible with external flash units, which ignite the vivid colors of the underwater environment and allows users to illuminate objects from different angles. Because the external flash is a unit activated via the on-camera flash, no sync cord is necessary. Set the camera to "External Flash," and it automatically de-activates the digital pre-flash.
To compensate for low-light conditions that naturally occur as divers travel below the water's surface, cameras can adjust the shutter speed and aperture automatically to compensate for difficult light conditions, ensuring vivid images without worry of underexposure.
Photos can be composed via a large color LCD monitor on the back of the camera; or users can frame subjects through a top-mounted SportsFinder. Either way, composition is simple, even when viewing subjects through a dive mask. To help conserve power during underwater adventures, users often shut off LCD monitors while the camera is on and compose photos using large top-mounted viewfinders.
With the many technological advances of recent years, underwater photographers now no longer have to compromise on quality. Users are almost guaranteed to return to land with a stunning set of images.
