In the world of IT, any amazing innovation usually triggers a string of other fantastic IT-related innovations. This is the case with underwater smartphone casings/housings. As smartphone manufacturers — read Apple — continue to enhance the functional capabilities of mobile phones, such as HD quality cameras, their applications have continued to expand. For instance, you can now use your iPhone to take high quality, professional photos on land. And, with a little sophistication, you can use it to take professional underwater photos, too. Whether you are a novice or professional scuba diver, surfer, sailor, or an everyday outdoor enthusiast with a keen interest in underwater photography, you can now use your smartphone to take exquisite HD underwater photos without risking damage to your expensive phone. Just get an excellent underwater housing, by considering the following features, and you are good to snap and splash at the same time.
If you decide to use your multi-functinal smartphone to take underwater photos, you must ensure that it has ample protection. In this light, you need an equally functional underwater casing that will ensure its safety. Luckily, there are special casings that are designed for specific smartphone models to enhance functionality and protection. For instance, if you decide to use your iPhone 6/6s underwater, buy the corresponding underwater housing for this model to ensure perfect fitting and operation. Also, consider the following protective features before acquiring one. First, the casing should be pressure tested and depth rated to your desired underwater sink/dive level. Top ones are rated to 100 meters. Secondly, the case should have a smartphone retaining system to hold your phone in place and amortize shock. Thirdly, the housing should be secure and properly sealed with a hardy and accurate main safety lock for effortless opening and positive closing.
As much as you are concerned about your smartphone's protection, while using it underwater, you must also be curious about the functional setbacks of covering it with an extra case. That is fair considering some of the touch-related inhibitions that have occurred after covering a smartphone in a low quality screen protector. As a professional, you will be relieved to learn that modern underwater housings enhance, instead of limit, the functionality of your smartphone. In other words, your iPhone's cameras will work even better if you get a good underwater casing with some of the following optical features. First, an optical dome lens with an underwater field of view that matches the land view — and one without distortions or soft corners. For longevity and obscurity, choose a scratch resistant dome lens, whose port has a safety locking mechanism, with anti-reflective coating. Secondly, an excellent underwater casing should have internal color correction filters for balancing underwater colors accurately. Finally, consider additional optical enhancements like a built-in optical selfie dome lens.
Again, this is a matter of functionality. You must be wondering if the underwater housing will inhibit your access to the smartphone controls — the answer is no. Top quality underwater housings are optimally designed with ergonomic controls that enable access to all the smartphone's camera functions. Before you buy, confirm full ability to access resolution and frame rate settings and also the following native camera features: stills, video, bursts, panoramic, time-lapse, and square shooting modes. You should be able to swipe to unlock your phone and a sleep/wake push button should be available.
