Is it difficult to take photos underwater with your mobile phone?
Photographing in the aquatic environment is not the same as taking a snapshot on the street or at home.Water alters light and colors, distorts focus, and can even affect the performance of your phone. Therefore, although taking photos underwater isn't rocket science, it does require taking into account a series of technical and practical details to ensure good results and avoid unnecessary risks.
Patience and good preparation are the keySetting up your phone, understanding how water refraction affects the image, properly protecting your device, practicing before embarking on your adventure, and knowing the limits of each piece of equipment are essential steps for obtaining clear and safe underwater photographs.
Water absorbs light and colors, especially red tones, making photos appear bluish or dull. Additionally, surface movement, and turbidity can affect sharpness and composition. Therefore, you should adjust some settings and usage methods to get the most out of your phone's camera.
Waterproof Phones: How to Know if Your Device Can Get Wet
Not all phones are designed to be submerged in water without damage.Before attempting to take an underwater photo, it's essential to check your smartphone's technical specifications and look for the corresponding IP (Ingress Protection) certification.
IP certification indicates the level of resistance of the mobile phone to dust and water according to the international standard IEC 60529. The most common are:
- IP67K – The device can withstand immersion in water up to 1 meter deep for up to 30 minutes.
- IP68K – Allows you to submerge your phone up to 1,5 meters for 30 minutes, offering improved protection.
Some high-end models, such as the iPhone 13, 12, and 11, or the Samsung Galaxy S23 Ultra, S21, and A52 5G, incorporate these certifications. However, Resistance is not eternal: continued use and impacts can reduce the tightness, and most manufacturers' warranties do not cover liquid damage.
Also, it is important to know that The certification guarantees resistance only to fresh waterSaltwater can corrode connectors and damage your phone. If you want to use your phone at the beach, it's best to further protect it with a waterproof case.
Essential cases and accessories to protect your phone
If your smartphone is not IP67 or IP68 certified, don't risk it.To safely take underwater photos, use waterproof cases specifically designed for underwater photography on mobile phones. There are two main types:
- Flexible pouch-type coversThey adapt to different models, are watertight, and allow you to access your phone through the transparent plastic. Ideal for swimming, poolside, and shallow-water photography. Examples include cases from Yosh or DiCAPac.
- Hard cases or professional cases: They offer additional protection and enhance the user experience, allowing you to dive deeper and providing easier access to your phone's physical controls. Ideal for more advanced photography or if you're looking for maximum security.
It is recommended to first perform a leak test with a piece of paper or napkin inside to ensure that no water gets in. Also, remember to dry the case and phone thoroughly after each use, especially after contact with salt or chlorinated water.
Additional accessories such as underwater tripods, submersible ring lights and floating mounts can help you capture better photos and avoid accidents during the session.
Camera settings and tricks for underwater photography
With your phone protected, it's time to adjust the camera to get the most out of it. Water significantly affects exposure, focus, and color, so it's a good idea to set the following parameters before submerging your device:
- White BalanceWater filters out warm tones, making photos appear blue. Select a white balance for "daylight" or "auto," and if your phone allows it, adjust manually until you regain natural tones.
- Low ISO: Choose ISO 100 or 200 if the light is good to maintain sharpness and avoid grain.
- Fast shutter speedConstant underwater motion requires shutter speeds of 1/125 second or faster to freeze the action and avoid blurry photos. If your phone doesn't allow you to adjust these settings, use "sport" or "action" mode, if available.
- Intermediate opening: If you can, select apertures like f/8 or f/11 to increase depth of field.
- Focus and burstSome phones allow you to activate burst mode to capture multiple photos in one second. This gives you more options to choose the best shot. Hold your phone as steady as possible and, if possible, activate continuous focus.
Don't take the photo immediately after submerging your phone. Wait a few seconds for the exposure to adjust to the difference in light between the surface and the interior, achieving a properly lit image. If you take the photo as soon as you enter the water, the photo will likely come out blown out or lack detail.
Practical tips for taking quality underwater photos
Technique is as important as equipment. Here's a summary of the top tips and best practices for taking underwater photos with your phone:
- Hold the phone firmly using both handsWater makes it difficult to control, and you don't want to lose your phone while you're in the middle of a dip.
- Get as close as possible to the object or person you are going to photographThe less water there is between the camera and the subject, the sharper and more colorful the image will be, while also preventing particles or bubbles from spoiling the result.
- Use flash or external underwater torches if the light is insufficientA lot of light is lost underwater, especially at a certain depth. Position your flash or light at an oblique angle to avoid glare.
- Take care of the compositionThe rules of photography also apply underwater: apply the rule of thirds, look for lines and shapes that draw attention, and rely on contrast to highlight the main subject.
- Play with reflections, bubbles and different perspectivesTry different angles, experiment with macro or wide-angle lenses if your phone allows them, and use your creativity to create original and surprising photos.
- Familiarize yourself with your equipment before getting in the waterPractice at home and use the pool to test all the settings.
Don't forget that it's recommended to limit immersion time to 30 minutes and not go below two meters deep, even if your phone is waterproof. And if you use it in saltwater, rinse it with fresh water afterward.

Common mistakes and final recommendations
Not all phones are equally water resistant, and misuse can cause irreparable damage, even to certified devices. So, remember these tips: Tips before setting out to capture the seabed:
- Always read the manufacturer's instructions and do not exceed the recommended times or depths.
- Avoid prolonged exposure to salt waterIf you use it at sea, rinse the phone and case with fresh water after use.
- Don't rely solely on IP certificationSome manufacturers, such as Apple, warn that the level of waterproofing diminishes over time and that the warranty does not cover liquid damage.
- Test the case before putting your phone in.If you have any doubts, do the first test with a piece of paper.
- Clean the lens before each photo and make sure there are no bubbles on the lens..
- Avoid excessive temperature changes (from cold to hot water, or vice versa), as condensation can affect the camera's performance and visibility.
All that said, practice, patience, and prioritizing phone protection are key to achieving stunning underwater photos. Today's technology and available accessories make it possible for anyone to achieve amazing results, as long as they follow the recommendations and limits of their equipment.
