How to Take Perfect Underwater Pictures with Our Waterproof iPhone?

Part 1: How to Produce Waterproof iPhone?

If we make a waterproof iPhone, we should use the specific waterproof case or the sealing techniques to prevent the phone from water, rain and even water intrusion at a certain period. Generally, water-resistant phone is divided into two types: structural water resistance and external water-resistant protection. Structural water resistance means the phone has few joints to seal the inside parts well, and the phone is enclosed with water-resistant materials. This structural design, which improves the overall capability of water resistance, can protect phone from rain and support underwater operation in a depth of 2 meters. Another is to use the external case to enclose the phone away from water. This box is specific to protect phone under 30 to 40 meters of water.

Part2: Ingress Protection Rating of iPhone

First, we should learn about the rating of ingress protection. Generally, we see the mark “IPXX”, and X is between 0 and 8. This is a standard that classifies and rates the degree of protection against intrusion. The digit 8 means the strongest protection.

① Level 0 is no protection; level 1 is against vertically dripping water; level 2, dripping water when tilted at 15°. Water falling as a spray at any angle up to 60° from the vertical has no harmful effect at level 3.

② Water splashing against the enclosure from any direction has little harmful effect at level 4. Level 5 is against projected water from any direction by a nozzle and level 6 is against powerful water jets from any direction.

③ At level 7, ingress of water has impossible harm to device performance in water within 30 minutes under 1 meter depth and protection can reach to 30 meters at level 8.

Notes of using waterproof iPhone:

① Pay attention to temperature and salt. The water temperature shall not be over 30℃ because the enclosure gets aging under the over-heated water. Salt can rust the mental parts. It is suggested that you put your iPhone into fresh water for a while if it is used under sea.

② Although most of water-resistant phones are dust proof, the large particles and mud can deform the enclosure and degrade water-resistant protection. Therefore, please keep the enclosure clean.

③ You should carefully check whether the enclosure is sealed well, and use the soft cloth to wipe water off.

④ The phone is damaged irreversibly once water intrudes into the internal parts. However, if you encounter the other problems, like slow operation, black and white screen, Renee iPassFix is the useful solution.

Part 3: Which iPhone Model is Water Resistant?

Waterproof iPhone models: iPhone 7, iPhone 7 plus, iPhone 8, iPhone 8plus, iPhone X, iPhone XS, iPhone 11, iPhone XS max, iPhone XR, iPhone 11 Pro and iPhone 11 Pro Max.

These models can reach to IP67 under the IEC60529 standard: iPhone 7, iPhone 7 plus, iPhone 8, iPhone 8plus, iPhone X, iPhone XR and iPhone 11. Namely, these phones can be against water intrusion for 30 minutes in a depth of 1 meter.

iPhone XS, iPhone XS max, iPhone 11 Pro and iPhone 11 Pro Max can reach to IP68, against water, dust and water splashing. These phones can be immersed into water for 30 minutes in a depth of 2 meters.

Part 4: How to Take Underwater Pictures with Waterproof iPhone?

With the advantage of water resistance, iPhone users can take many special pictures underwater. Here are tips for you about how to take perfect underwater photos with your waterproof iPhone.

① Key elements: water quality and light

Light is key for a perfect picture while the underwater light is very dim. The deeper water is, the weaker the light is. We suggest that you take underwater photos in a depth of up to 1 meter where the light is acceptable. In addition, you should take photos in sunny days, preferably from noon to afternoon, to ensure the full light.

Another important element is water quality. As we all know, the low water quality has negative effect on light through water. That will be hard for us to take perfect photos.

② Wait for calm water

If you don’t want ripples to cover on your photo, you should patiently wait for calm water. Also, you can put the selfie sticker into water in advance and then wait for the suitable time to capture your perfect photos.

③ Take split underwater pictures

Split photo is one of the photography styles. The split underwater photo includes half of the objects over water and half under water. You can take special photos, totally different from those in the fully underwater scenes.

④ Take photos for fish group

If you want to take photos for fish group, you can select the fish tank, the clean river and sea, and then use some food to attract fish together. However, iPhone can be against water in a depth of up to 2 meters. It is only recommended for snorkeling under shallow water.
