Let’s Talk About Light & Diving

Do you remember how light behaves underwater from your dive training?

In various scuba diving courses, such as PADI Advanced Open Water Diver, Deep Diver and Underwater Digital Photographer you are taught about light (about colours). The concept is quite easy to grasp as your visual experience while diving is directly liked to it.

In a nutshell, light is affected by the distance it travels underwater (depth and subject distance) and topside conditions (time of day, weather and surface conditions). So it is all about how much light goes in, and how far it has to go.

The following graphic from Dive Photo Guide illustrates this concept nicely. You can see that some colours, such as red and orange, rapidly disappear when going through water.

So, you want to fully appreciate the amazing underwater world? Introduce your own light source!

Using a dive light will help restore colours. Get a good dive light, and get close. This will not only boost your visual experience, but it will help you find things.

Let’s take the frogfish as an example. This particular froggy was about 25 meters deep hiding in wooden rubble from a wreck. Without a dive light, it would be very easy so swim by without ever noticing its presence, as you can guess from the greenish image below.

Also, when armed with a camera, you want to show your subject in all its glory on a photograph. Your lighting technique will give life to your photos. Compare the images and see for yourself.

Phuket Diving Trips – How it Works

I've dived in many places around the world and it's fair to say that scuba diving in Phuket differs greatly from anywhere else I've experienced. Most of the best diving spots in the world are fairly remote with limited infrastructure but Phuket is very different negating the necessity of staying in a dive resort or very close to the boat departure point. As a result divers come from all over the island to join us, so if you're wondering how it [...]
