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.

Dehydration And Scuba Diving

We as any good dive boat should provide water free of charge on our day trip tours but even though it's free when we calculate the guest to water consumption ratio we find you're coming up well short on what you should be drinking. This has to change. Dehydration in scuba diving can make you more susceptible to decompression sickness. It's not the most common cause but staying hydrated is good practice for diving health.
