So often in our haste to take pictures underwater we forget an important fact: to be a good underwater photographer, you first have to be a good diver. The good news, however, is that being an aspiring photographer doesn't have to interfere with your development as a competent diver. In fact, it often accelerates it.
Many of the skills we develop in life are born out of necessity. Likewise, mastery of fin pivots, for example, may come out of the need to get in close to a photo subject rather than rote repetition. The ability to hover effortlessly may arise out of shooting stingrays and not advanced certifications.
The line is drawn where photography interferes with your ability to be a safe diver. It is your responsibility to consider the factors leading to a dive. If you don't think you will be able to take pictures without harming the environment or doing so safely (including your responsibilities to your buddy), it is on you to make the call and leave the camera behind.
Usually this is not the case. Enjoy learning how to take photos underwater, and appreciate the side benefits it has on your abilities as a scuba diver. You may surprise yourself at just how competent a diver you become in the process.

I randomly came across this interesting device. It's an ear dryer, for drying out the insides of your ears after swimming or scuba diving. It even warms the air it blows into your ear canal.
I was a little surprised to see this device selling for \$100 USD. Who would pay that much for this, especially when you can make homemade swimmer's ear for a couple of bucks?
I started reading the comments on the sales page and it hit me. If you suffer from chronic ear infections, then anytime you come out of the water you are ...
This is an interesting tidbit about human physiology, although it applies more to free-diving than scuba.
Try this out: take a breath and try to hold it. Unless you practice this sort of thing, it won't take long before you feel the urge to breathe, that tugging in your chest. Where does that feeling come from?
Most people would guess that your body needs oxygen, and that it translates this need into a physical response urging you to breathe. This is close, but not correct. In fact, this reflex comes from the other half of the same cycle.
Most fish identification articles here have been admittedly focused on Caribbean creature. I'll try to balance it out in the future, starting today with the longhorn cowfish.
Longhorn cowfish can grow up to 20 inches (50 cm) in length. A member of the trunkfish family, they are characterized by their distinctive box-shaped body. In addition, the long, forward protruding "horns" on the front of their body give these fish their name.
Their bodies are yellow and covered with small white spots all over. Their fins are made of translucent rays, and include dorsal, anal, and caudal. They ...
Have you ever heard of this? The mammalian dive reflex is a reaction in your body to cold water that allows you to stay underwater longer. It is used extensively by aquatic mammals, like otters, dolphins, and seals. It is also observed in animals like penguins and, of course, humans.
In humans, the water has to be colder than 21 C / 70 F, and it has to be in contact with the face. The sensitives nerves in our nasal cavity are responsible for relaying this information to our brain. When this happens, up to three things can occur:
- Your heart ...
Nobody likes waiting, and they especially don't like people who make them wait. Don't be that person!
When diving from a boat, make sure you are completely ready before moving to the platform. Dawdling on the edge of the boat is highly inconsiderate for those jumping in after you, the crew helping divers off the boat, and your buddy waiting in the water. It's also dangerous, since a jolt to the boat could toss you overboard.
Before moving to enter the water, check that you have done everything to be ready, including
- Complete buddy check
- Mask defogged ...
With over 28,000 individual species of fish (and the number keeps growing), it would take about 540 years for the fish identification series to cover them all.
Fortunately, we don't have to do that. Using some common sense, we can get that number down to something reasonable. First, we can limit based on fish we may actually encounter while scuba diving. With this filter, the number drops to around 4,000. This is still too many, but much closer to being manageable.
Second, we can combine fish that are nearly the same. For instance, it is not critical ...
You may have seen this floating around the web, but The Cayman Islands are holding a contest for a 7-night stay for two people at a resort, along with airfare!
To enter the contest, you must become a fan of The Cayman Islands Facebook page, and in 100 words or less describe your perfect day on The Cayman Islands.
The contest ends June 24, so you have about a month. I've never been to The Cayman Islands, but I'm sure they're quite a popular destination for a reason. Given the small time commitment, there's no harm ...
Duane over at Precision Diving posted an article a few weeks ago on the top 5 places to dive before you dive---I thought I'd play along.
Most of my scuba diving experience has been around the Caribbean, so I tried to balance my list to not be entirely comprised of south Pacific destinations.
- Tonga - Reading Tony Wu's Underwater Photography Blog has given me Tonga fever. Sprawling islands with many dive sites, some untouched, makes this a diving paradise. I'd love to spend 1-2 weeks on a live-aboard out that way.
- Thailand - Phuket, Ko Samui, Ko Tao ...
On Saturday we went to Diving Unlimited International's (DUI) Dog Rally and Demo Tour at Dutch Springs, PA. While there, we completed our requisite dives for a Drysuit Specialty. Look out in the future for a drysuit diving article.
First off, the demo tour was pretty cool, and I would highly recommend it for anyone interested in drysuit diving, for several reasons:
- Not many places rent out dry suits. This can make it difficult to try one or get your specialty. Often, divers have to make the expensive purchase before even trying out a drysuit.
- If you can rent ...
