CHAPTER 2Understanding Your Camera’s Main Settings

Canon PowerShot A570 IS, INON UFL-165AD fisheye lens INON D-2000 strobe, ISO 200, f3.2, 1/60th sec

2.1 Getting Started - Choosing The Correct Set-Up Options

Getting Started: Before you start taking fabulous underwater photographs, there are a couple of settings to change in the camera’s menu which are really important to give you the best chance of getting nice sharp pictures.

Always make sure that the face detection mode is switched off, or the AiAF/AF mode is switched to centre or flexizone in the case of the Canon PowerShot G series. This will stop your camera automatically selecting what it thinks is the main subject in your frame. Although it works very well on land, when underwater your camera may indeed select a rock as the subject instead of the moray eel hiding in it.

Some cameras such as the Fuji FinePix range have a tool called ‘Quick AF’ in their menu set-up which helps ensure a faster shutter response and can be useful.

Digital Zoom: Make sure that the digital zoom is switched off. Using this to get closer to your subject only makes it appear closer digitally and actually makes the size of the resulting photograph smaller. It is always best to get closer to your subject by physically getting close, or by using the optical zoom but always remember that no photograph is worth breaking any coral or damaging any fragile marine life for.

Reef hooks are great for helping you balance underwater while taking your photographs, or of course using a finger to balance on a rock or in the sand. Just be careful there are no stonefish or scorpionfish hiding where you intend to stabilise yourself otherwise you could be in for a nasty shock as well as hurting marine life.

Image Stabilisation: If you have an image stabilisation mode, always make sure that it is switched on as this will give you a helping hand in reducing blur and increasing your chances of sharp shots. However, you shouls be aware that sometimes your ISO can increase by having this feature turned on.

Grid Display Mode: Using the grid display mode can help your composition underwater. You can usually find this in the menu setup. Some cameras also have a high definition framing option where the high definition 16.9 crop is automatically displayed.

Video Set-Up: If you are using the video, always make sure that it is set to the relevant country’s system of playback where you are, i.e. PAL for the UK, Europe and Asia and NTSC for the Americas so you can view your movies on your TV at home.

Image Size: Always choose the largest size setting possible when taking photos. This gives you more pixels so you can print the image larger, as well as allowing you room to crop your image if you wish and still have enough resolution left to make a nicely sized print. The number of pictures which can be taken at your current setting is normally displayed at the bottom right hand corner of your display.

Image Quality: Always select the fine option for higher image quality. This will compress your image the least.

Time to get playing and understand all of those controls on your camera. Let’s go!

2.2 Automatic Underwater Mode

Automatic Underwater Mode – What It Means and When to Use It: There are two things camera manufacturers know we suffer from as underwater photographers - loss of the colour red within the first few metres and fast moving subjects.

Therefore a new setting was introduced by most of the compact camera manufacturers – the underwater mode, and in the case of Olympus compacts, three underwater settings, Underwater Wide 1 and 2 and Underwater Macro. SeaLife cameras have four different underwater settings including one which is especially for snorkellers.

The camera chooses the aperture and shutter speed it thinks is correct to expose your picture correctly in the given circumstances and adds an electronic filter to neutralise the cyan colour underwater. This setting should be used by itself and not with red filters, or with flash when very shallow, otherwise subjects can end up looking pink. However, this could work in your favour if you are taking pictures of red objects such as sponges or orange anthias, as the effect enhances their natural colour and gives the resulting photograph a far punchier look.

Shooting with the underwater mode is appropriate from about 1.5 metres underwater to about 10 metres, depending on the amount of available light. Using the mode in very shallow water could again make your subject more pink. Using this mode at depths greater than 10 metres may lose its effect and this is where manual white balance or an external strobe will be more appropriate to replace lost colours.

The main disadvantage of using this setting is the lack of control over the ISO which could result in images suffering from grain or digital noise where the pixels enlarge and are sometimes red. This usually happens when taking pictures in deeper or darker waters.

Users of Canon’s PowerShot G series or the PowerShot S90 have the ability to change some extra settings on the camera while in underwater mode such as ISO and exposure compensation. The vivid mode which can be found in My Colour Options (under the Function Set menu) can also be accessed to make the colours richer.

These photos of the pier were taken at a depth of 2.7 metres. For the top one I used a Fuji F31D and an INON UFL-165AD fisheye lens on underwater mode. The aperture was f2.8 and the shutter speed was 1/60th sec. The bottom one shows the same photograph but taken with a Canon PowerShot 570 using manual white balance – the pink magenta tone became very apparent in the shallow waters at the surface.

These reef shots were taken at a depth of 7 metres with, and then without using, the camera’s manual white balance with a Canon IXUS 980 (US model SD990). Note how the picture on the left, taken with underwater mode, has much richer colours compared to the one on the right.

This green sea turtle was seen by Alex Cook in Egypt on his first ever underwater photography dive. He was so shocked he couldn’t take the photograph and Noeleen Graham, his dive guide, grabbed the camera and took this shot. Taken with a Canon PowerShot G9 with underwater mode (without flash) in 3 metres, it worked perfectly to keep the turtle’s colours rich and punchy while keeping the beautiful dappled light effect of the water on the sand behind.

Using the underwater mode when you are near the surface can render your subject a little too pink. However, using it here with my course guest Dale Turland-Ord, has helped us to see what our hair looks like with a red tint without wasting time and money at the hairdresser!

Some compact camera users get fantastic results from using the underwater mode with either their built-in flash or an external flash-gun. I’ve seen some compacts (such as the newer Fuji FinePix F200 EXR) produce richer and more vibrant pictures using the underwater mode with the macro setting and the built-in flash.

Try using the setting in shallow waters and see what you think and whether you like the effect it gives you. It is a nice, hassle-free way to take some fabulous looking photographs when you are surrounded by lots of ambient light.

2.3 Programme Mode

On many compact cameras this is the only mode available, and it can be the most versatile and easiest to understand for anyone getting into underwater photography. Confusingly, some cameras such as Canon’s older IXUS range and the older Fuji FinePix range call this the ‘M’ mode, but it has the same functions and benefits as the ‘P’ or semi-automatic mode found in cameras such as Olympus, Nikon and Sony.

The camera chooses an aperture and a shutter speed for you to expose correctly. You have a choice of being able to use other settings to help enhance the resulting photograph such as ISO, white balance menus, exposure compensation, colours and macro mode.

This is a good choice when shooting with natural light near the surface or if you are using a strobe, as you have a better chance of exposing your subject to its best potential by being able to tweak settings.

For any beginner, this is a great mode to use and offers far more flexibility than the underwater scene mode.

2.4 Understanding Aperture Settings

The very mention of anything other than the programme or ‘green square’ mode can make anyone new to underwater photography freeze when attempting to move out of these settings. Having the confidence to use different aperture settings can help to create striking images when used together with a strobe or even your camera’s built-in flash. So where do you start and what does it all mean?

The aperture (the f number) helps control the depth-of-field of the area in front of and behind your subject – which remains in focus. A shallow depth-of-field gives more prominence to your subject by throwing the background and foreground out-of-focus. Using the maximum depth-of-field gives overall sharpness to an image and is ideal for close-up subjects.

All compacts have the ability to get sharp close-up subjects by using macro mode. This also helps the camera to focus on subjects when using a wide-angle lens for close-focus wide-angle shots.

Compacts naturally have a good depth-of-field as the camera’s sensor is so much smaller than SLR cameras. There are also fewer f numbers to choose from – the range normally starts at f2.8 in most models and typically goes to f8 or f10. Even though

this number seems much lower than f22 or f32 offered with SLR models, the range of depth-of-field achieved is more or less the same.

Choosing an aperture of f2.8, or using the camera’s standard programme mode (or M mode on the older Fuji FinePix or older Canon models) with a wide-angle lens is excellent for letting in the maximum amount of light possible.

An aperture of f8 suits close-up subjects where a large depth-of-field is required. For cameras which don’t have aperture priority or full manual controls, simply pressing the ‘tulip icon’ will automatically give the chosen subject the greatest depth-of-field possible. Using this button with the forced flash within a foot of a macro subject gives wonderful sharpness and punch.

Control over the aperture is extremely important when using an external strobe. Too much light will burn out lighter subjects and too little light will make any subject appear too dark. When photographing reef scenes with a wide-angle lens, a middle aperture of f5.6 usually produces effective results. As always, experimenting is key at different depths and environments to produce the correct exposure for any subject.

2.5 Understanding Shutter Speed Settings

Whereas the aperture determines how much light gets into the camera, the shutter speed determines the length of time it has to make the exposure on the camera’s sensor. This is measured in fractions of a second. A standard shutter speed for underwater use is 1/60th of a second to ensure that your picture remains sharp, but this, of course, is very dependent on your subject. If it is fast moving you will need a faster one to prevent it from being a blur. This can also be increased by changing your film speed to a higher one.

Some of the more advanced compacts have their own shutter speed priority mode (such as the older Fuji FinePix range) or a full manual mode where it can be changed independently from the camera’s aperture setting (such as the Canon PowerShot, Olympus, Sea & Sea, Panasonic, some of Sony’s cameras, Nikon’s Coolpix range or the Fuji’s newer FinePix range).

For those who have the ability to independently choose the shutter speed setting, the possibility of using the fastest speed in combination with your smallest aperture (i.e. f8 or the tulip icon) can create wonderful effects where the macro subject stands out from the background. Increasing the shutter speed is also useful for freezing the sun’s rays near the surface of the water. Just start from 1/60th sec and increase the shutter speed to 1/500th sec in clear water and see how the background gets darker. Some cameras have a faster shutter speed, however, when using either the built-in flash or an external strobe, this will only usually synchronise at 1/500th sec. Check your instruction manual for more information.

2.6 Understanding Manual Mode

Manual mode gives control over both aperture and the speed on the camera allowing them to be independently changed, creating a correctly exposed subject and a background to complement it. This is often the most daunting setting for a

This frogfish was found whilst diving in Taba Heights, Egypt. The first picture was taken with an aperture of f5.6 to let in more light to show the background and the habitat of the frogfish. The second was taken with an aperture of f8 to allow in less light and by getting closer, I was able to focus on the head of the frogfish to create a stronger image.

This photograph of a reef scene was taken with a Canon IXUS 980 (US model PowerShot SD990) with an INON UFL-165AD fisheye lens and an INON S-2000 strobe. The first photograph is overexposed as the aperture was f2.8. Changing the aperture to f8 corrected the overexposure. Both were taken with an ISO of 80.

Pink Soft Coral, Ras Mohammed Marine Park, Red Sea, EgyptTaken with a Sony Cyber-shot W7 by Brad Nolan whilst on a Red Sea workshop with Emperor Divers. Even a simple camera with just the built-in flash and the ability to change the shutter speed can create a wonderful black background and make the subject really stand out. Brad also used the camera’s macro mode to ensure the soft coral was sharp.

beginner but once grasped, I promise, you will never go back to using automatic settings. Models such as Sea & Sea’s DX2G, Canon’s PowerShot G range, Panasonic Lumix as well as some of Sony’s Cyber-shot models and Nikon’s Coolpix range, offer full manual control. When purchasing a new camera it is well worth making sure it has a full manual mode if you would like to get really creative with your underwater photography. Always make sure the buttons that change the shutter speed and aperture are still available to use once the camera is in an underwater housing – or that you know where the shortcut keys are in order to be able to do this.

Some models such as Canon’s PowerShot G range, offer a shortcut key signed S which when pressed with the left and right toggle buttons changes both your aperture and shutter speed settings as the wheel is de-activated when underwater. However, this can vary with the different housings available for each camera and some which are accessible with one kind, may not be with another.

For more information on settings to use in different situations, have a peek at the chapter on composition. This covers all kinds of scenarios, and offers a good way to get started on achieving those shots you’ve always dreamed of.

By increasing the shutter speed here, the background behind the lionfish is gradually reduced to a darker blue and then to black to give a different effect to the same subject. This lionfish was taken with an Olympus SP-350 and an INON Z-240 strobe.

Bright light can often create a digital burnout effect at the top of photographs when in shallow water. By increasing your shutter speed, or using your exposure compensation (EV) tool on the minus setting, this can help to freeze the rays of light. Remember to make sure your film speed is as low as possible as this will also help to prevent overexposure of the subject.
