Here are a few basic principles for successful underwater photography when you are a beginner. Six simple tips to start making fun pictures underwater...

Because underwater photography is more difficult but much more beautiful than photography without water... ???? ????

My evolution from compact camera to SLR camera

I started underwater photography in 2005. My very first camera was a disposable case, with a silver film in it, all in a waterproof plastic case with a yellow background. We found this in tourist shops & #8230;

I liked it so much that I bought my first digital camera right away. I first "made" myself (and my eye) with a modest compact camera, the little Canon Powershot A95from 2005 to 2009. I learned a lot in underwater photography with this "basic" camera, which is quite sufficient for beginners. This knowledge was very precious to me to progress later with my "big" reflex camera ( the Canon Eos 7D).

After a while, I went through the possibilities of the compact camera and this camera finally gave up... So I switched to the reflex in early 2010 (Canon Eos 7D(Ikelite box). Over the dives and years, with experience, my images have gradually improved in quality. Even today, I continue to perfect myself, to try to improve my practice... Underwater photography is an incessant learning process!

Here I want to go against a common misconception: many people think that a compact camera does not make it possible to achieve beautiful images underwater. THIS IS FALSE! Today's small cameras, even the affordable ones that are the first choice when starting out in underwater photography, are jewels of technology, capable of producing beautiful images, provided you keep a few basic rules in mind.

Because of course, it is not the camera that takes the picture (who misses or succeeds), but the person who presses the shutter button... 😉

I've seen people make beautiful pictures with very simple equipment. And others make rotten pictures with very sophisticated and expensive equipment...

I summarize below some tips and advice to think about underwater photography ... before, during and after the dive!

1. Control (really) your buoyancy

First imperative, which concerns more the diving technique than underwater photography: you have to be really comfortable with your buoyancyincluding knowing how to do lung-ballast without even thinking about it.

  • In macro, in particular, you have to be able to stay close to the subject without touching anything. It is excluded from "#160; bump & #160;" to corals or rocks, at the risk of injury and damage to the environment.
  • Must also know how to move close to the bottom without lifting sand& #8230; Learn to palmer like a frog (the famous frog kick). Otherwise, hello particles in suspension that will make white spots in the flash light!
  • To approach fish, avoid frightening them and causing them to flee. #8230; We therefore avoid sudden movementswe do not rush to his subject, we slowly palm and breathe calmly.

Last but not least, it is essential to never put yourself in danger when you are caught by the photo to take. Watch out for all the usual stuff (current, depth, air conso, deco). And then we keep an eye on his team and his team to not lose them (and we warned them before the dive that we might "hang out" a little because of the photos).

2. Know your camera well

Sounds stupid, but before getting into the water with his camera inside a waterproof case, better thoroughly know all the buttons, settings and functions of said apparatus.

  • The best is to train, dry, to handle it in its box to find easily the buttons that one needs.
  • Better to favor a device model offering Manual mode (M), with a well designed box, allowing access to all settings. You have to be able to adjust yourself the speed (or exposure time), opening and sensitivity (ISO) to control what you do underwater.

Yes, the picture under water, it's still the photo & #160; Photographing means "& #160; writing or painting with light & #160;" It will therefore be necessary to learn or revise the basic principles to work light, that is to say to understand how to combine the three parameters shutter speed / aperture / sensitivity

3. 3. Conduct field trials

For the photographic technique proper & #160; the best is to start to practice and try different settings underwaterThe goal is to find the ones that work, and to learn how to adjust the three parameters (sensitivity, speed, aperture) according to the conditions...

Experiment, take it as a game, have fun! Understand that there is no one setting that will work in all situations, there is no such thing as a single setting...

  • Photo of near (macro) & #160 ;: At the beginning we train on "easy" subjects, i.e. not too small and which do not move (starfish, nudibranchs, corals). It's easier to get your hands on almost immobile subjects. You have to put on the flash, whose white light will bring out the colours, and learn how to adjust the amount of light you send to your subject.
  • Far photo (wide angle) : for more distant subjects or ambient photos, you have to play with the natural light coming from the surface. We take into account the position of the sun, we think about the image we want to make before shooting, we think about the composition...
  • The flashes in photo of atmosphere: if you only have an internal flash on a compact, you have to deactivate it, because it will light up the particles suspended in the water, which will then look like snow on the picture! If you have one or more external flashes, you can use them to illuminate a foreground, otherwise you can deactivate them too: remember that their light does not go beyond one or two meters.
  • What about submarine mode? Some compact devices offer this mode, recognizable by a small fish logo... All are not equal. Test to see the result. But sometimes it's really bad. Avoid it if you don't get a good picture with it.

Why is it worth switching to manual override? This allows you to keep control over the three essential parameters in underwater (and land) photography: sensitivity (ISO), shutter speed (Tv), aperture (Av). These are three ways of influencing the amount of light that is allowed to enter the "darkroom" of the device.

In manual mode, unlike automatic or semi-automatic modes, it is not the unit that decides how to adjust one of these parameters, nor how to combine the three (underwater, it can be "misled" by the very particular conditions of the underwater environment and choose aberrant settings).

How to tame the manual mode underwater? Start by fixing sensitivity (ISO) from 100-250 (for very bright conditions) up to 400-800 (dark conditions). Then set speed (Tv) i.e. exposure time: do not go down to a speed lower than 1/60th or 1/90th to avoid blurred movement. Then, as you take pictures, you will adjust opening (Av)This means that you open or close the lens, depending on the situation, until you get a correctly exposed image.

Underwater photography, I repeat, it's still photography... 😉 So if the notions of "sensitivity, speed, aperture" don't really speak to you, start by training yourself and learning these basic principles, by taking a photography course, for example, even on land. When you understand how a camera works, it immediately becomes much simpler...

4. Dosing of artificial light

The water gradually absorbs the colours. The deeper you go, the bluer everything becomes... To have color in underwater photo, it is necessary to bring white light on its subject, with a flash.

The red disappears after 5 m, followed by orange between 10 and 15 m, then yellow between 25 and 30 m... Underneath everything is bluish, greenish. Even without taking a picture, it's always nice to carry a lamp to discover the true colours of corals and fish. We are often surprised to see a brownish or greenish tuft on the reef turn into a bright red grove! (Source: Wikimedia Commons / Thomei08 / CC BY-SA 3.0)

Good to know: a lamp or a headlight cannot really replace a flash in a photo. Even though you can make interesting pictures, it's much harder to get a satisfactory result and you really have to take the time to play with your camera settings.

It is also important to remember that the flashes, whether integrated or external, can only illuminate close subjects (one to two metres away). So I repeat what I said earlier: for distant subjects, you should not use them, the particles in the water will make white dots on the image...

  • Think about putting a diffuser in front of the flash, the light will be better distributed.
  • Learn how to gauge the right distance for your shots, moving away from or close to the subject, to avoid having a "burnt" or too dark picture.
  • Adjust the dose of light that you send on your subject & #160 ;: depending on what your equipment allows, you can adjust the flash output, vary the exposure time and / or the aperture.

Try to make sure your subject stands out against the blue background of the water, rather than taking it with the bottom or a falling in the background. This allows to de-clutter the image and to put in values nudibranchs, hippocamps or branches of coral, for example. By playing on the exposure time and / or the opening, we can make this background take a dark hue, from black to dark blue.

5. Making several pictures of the same subject

Do not hesitate to "& #160; shooter & #160;" once, twice, ten times the same subject to have a good picture in the pile, even to erase the less satisfactory then, after understanding why they are missed & #8230; We learn from his mistakes.

  • Warning, one is sometimes deceived under water by the rendering of the digital screen& #160 ;: we have the impression that the image is successful, and we are very disappointed in discovering afterwards, on the larger screen of the computer, that it is fuzzy for example.
  • Do not hesitate to change your point of view, to multiply the different frames. Avoid photographing the subject from above, but always try to meet the eye of the fish, or the dress of the nudi

Remember to select the largest possible image definition & #160 ;: L as "#160; Large & #160;" or S as "& #160; Super-thin & #160;", depending on the devices & #8230; After, on the computer, it allows tighter cropping without too much loss in definition.

6. Special compact devices: beware of batteries and humidity

We must be careful also to always to dive with well charged batteries. Since the flash is much used underwater, the batteries of compact cameras can be drained quickly.

  • Always inspect the seal and lightly grease with silicone gel to keep it in good condition. Often, I prepare my box the night before, quietly. It avoids the catastrophes due to the hasty preparations in the early morning.
  • If possible, leave the device + box in a water tank just before the dives, so that it starts gradually at the right temperature (it avoids the condensation that makes "& #160; steam & #160;" on the lens, very annoying). Do not ever leave it in the sun & #160!
  • For compacts, do not hesitate to slip one or two small bags of Silicagel or equivalent in the box to absorb moisture, always to prevent condensation, favored by the batteries that heat. I did not have this problem with my SLR, the batteries of the flashes being external.

It's worth having extra batteries in reserve on the boat. It is always when one is in drums of battery that one makes fabulous underwater encounters & #8230;
