5 Must Haves To Get Started With UW‑IMAGING

You love diving? You love to take pictures and videos? Then it is time to talk about becoming an underwater photographer!
A underwater photographers Wishlist is endless. Nevertheless we will introduce you to the “5 Must‑have Items to get started with UW‑Imaging”!

NR. 1 – The Camera

First of all, obviously ‑ you need a camera! There are dozens of awesome cameras out there, but just a handful of them is suited for underwater photography. As a beginner you want to start with something small and simple, like a digital camera! Sony’s RX100 series, like the Canon G7x series or the Olympus TG‑series are notoriously known amongst underwater photographers. Despite their small size they are really good entry‑level cameras. Especially in underwater photography most people have to travel to get to the dive spots and this small camera size can be a real game changer!

(Obviously you could also go for a simple ActionCamera… but if you want to take things seriously and actually recognize something again on your pictures you should stay away from using an ActionCamera for your underwater photography🤗)

Nr. 2 – Underwater Housing

Most cameras are NOT waterproof. Therefor you need to get a underwater housing which suits your camera. Many camera‑manufacturers started to build their own waterproof cases. Some of them are good others should be avoided.
There are 2 materials most commonly used for underwater housings:
Polycarbonate ‑ cheaper, lightweight and perfect for traveling.
Metal ‑ expensive, heavy but extremely durable and rugged.
The market leading companies for polycarbonate housings are Fantasea, Ikelite & SeaFrogs. For metal housings you should have a look at Nauticam, Isotta or Auquatica.

Nr. 3 – Wide Angle Lens

Now, as you got your camera & underwater housing you need to decide, which style of photography you want to pursue.
If you choose to capture the big stuff like coral reefs, sharks, schooling fish or people ‑ you should consider to get a underwater wide angle lens. These so called “wet lenses” are mounted on the lens port of your housing. They broaden the field of view by correcting the magnification that happens underwater with a flat port.

Nr. 4 – Macro Diopter

This is a must have for all those macro photographers out there: the wet macro (or super macro) diopter. Using this piece of equipment brings your right up close and personal to your favorite underwater creatures.
Macro Diopter work by shortening the focusing distance between the camera and the subject so that the subject fills the frame.

Nr. 5 – Underwater Strobe or Video Light

As you learned and observed in your Scuba Courses, the color of light is lost underwater. The deeper you venture, the more colors disappear.
To correct this loss of color you can use either a strobe or a video light.
(This tool is rather advanced and will take practice to be mastered. If you want to know how to correct your underwater colors without a strobe/light, check out our Article on http://www.lunatics‑world.com “Finding the right White Balance”

Finding the right White Balance

Everyone new to underwater photography wonders: “Where are the colours?”. Maybe you can identify yourself. After hours of diving and countless pictures taken you are sitting on your balcony, having a cold beer. You are reviewing your media and suddenly you wonder what happened to those beautiful colours on your images. Magnificent reefs and beautiful school of fish suddenly appear dull, green and boring. Let’s have a look on how to fix this issue in the first place.

When taking pictures underwater you need to keep in mind, that water absorbs the colour of light. Therefor, the deeper you venture, the less colours will be visible on your pictures.
You will notice, that the colour “red” is being completely absorbed at a depth of 10 meters, followed by “orange” at 20 meters, “yellow” at about 35 meters and “green” at a depth of 45 meters. Everything deeper than that will appear in a blueish colour.

There are three different ways on how to restore these colours on your images. Some techniques work better than others and might also depend on your camera system. But one word is enough to rule them all:


The process of adjusting the colour composition in a picture is called white balancing. You can accomplish this while taking a picture or in post production. When setting the White Balance on your camera, you are simply telling your device, which colour in your current setting is “true white”. In result, the cameras algorithm calculates all other colours according to the “true white” you set.


If you are capturing the underwater world with an action camera like a GoPro, there is little you can do to make the colours pop, but one of the following tips might also work for you.

1. Automatic Underwater White Balance

When choosing between different White Balance settings in your camera you might come across the “Automatic Underwater White Balance” (usually marked with a FISH symbol). Not every camera supports this feature. Cameras like the Canon G7x, Sony RX100 or the Olympus TG series for example allow you to use Underwater White Balance. As every cameras colour algorithm is different, the results from different cameras will vary in style and colour. Automatic UW White Balance is a good way to get started but might not work properly at greater depth.

2. Manual White Balance

Every digital, mirrorless or DSLR camera allows you to adjust the White Balance manually. Depending on the manufacturer and camera system you would have to take a picture of something white (white fins or slates e.x). Then you need to tell your camera that this image contains the “true white” and your camera will calculate the whole colour spectrum according it. This setting is usually found at the very bottom of the White Balance settings.
Adjusting your White Balance manually gives you greater opportunities, better results but can sometimes be quite tiring: Remember, the colour spectrum is different at every depth. Meaning you would have to adjust the White Balance every time you go shallower or deeper. Some cameras give you the option of saving multiple custom White Balance settings. This way you can set 3 different White Balances for 3 different depth and change them according to your depth.

3. Post Production White Balancing

Everything is possible in post production. If you have experience using editing programs like Adobe Lightroom or Photoshop you know, that you can change the Temperature and Tint of a picture in post production which is actively effecting the White Balance of your image. Lightroom gives you the option of selecting a white object on the frame. According to your selection it will adjust Tint and Temperature of all colours.
Changing White Balance in post production is a great tool to rescue your underwater colours but it should be the last resort. The quality of the image suffers under too much editing and post production. Therefor you are advised to capture your images straight from your camera with the right White Balance setting and only “manipulate” the image afterwards if truly needed.

Conclusively we would advise you to set your White Balance manually for the best results. If you are still not happy with your colours, the only way out is to invest in underwater strobes. Only with underwater strobes the true colour of the underwater world will comes into light. Learn more about underwater strobes in our next article.
