Then Apple said: Let there be light! And there was the LED iPhone flash! Just like the built-in smartphone flash next door, your iPhone's gleamers are used as a trusty flashlight, offering some assistance in your quest to find those car keys under the couch. And more than an iPhone flashlight, iPhone's LED flash is the perfect match for your phone camera, backing you up with good photography lighting for your late night photo ops.
The iPhone flash is known for its True Tone LEDs. This means that the LEDs are capable of switching up the colour temperature depending on the lighting in the room. This ensures you get just the right amount of light you need.
If you're using the iPhone flash as a flashlight, you can access it in the Control Center by swiping up from the bottom of your screen. Tap on the flashlight icon to turn it on or off. To use the flash when you're taking a photo in low light scenes, just open the camera app and tap on the flash icon on the left upper portion of your screen and tap 'on' to enable or 'off' to disable.
But aside from using it as a good ol' trusty flashlight or photography tool, you can also use the iPhone flash in other less obvious but totally cool way. Here we've listed some nifty tips for you to you get more out your iPhone's built-in LED flash!
Receive Notifications with the iPhone Flash
Because nothing says 'look at me' more like a loud ring and alert tone in a library or in a meeting. As a matter of fact, even just a vibrating phone will get those heads turning. And a missed important notification is just as dreadful. The answer: a visual phone alert! As long as it's not pitch-dark in the room, where you find your iPhone's flash competing with the projector, then you're totally fine. To enable your iPhone's LED flash notifications, simply go to 'Settings', tap on 'General' then choose 'Accessibility', scroll down to 'LED Flash for Alerts' and toggle to switch 'On'. This goes without saying that you have to position your phone facing down. Otherwise, you're going to miss the light notification. This would also suit you perfectly, if for any reason an audible phone alert just annoys you.
Use the iPhone Flash as a Heart Rate Monitor
I bet you never thought this would be possible with your iPhone flash. Well, it is --with a special app, though. The 'Heart Fitness' app is available for download at the iTunes app store for free and it works hand-in-hand with your iPhone flash to monitor your heart rate. Using the app is a breeze, you simply put your finger over the iPhone LED flash and camera lens. The LED flash then reads your pulses as your body pumps blood in and out of your finger. Of course, nothing beats going to your physician, but this is as accurate as a mobile heart rate monitor can get.
Utilise iPhone Flashlight Apps
A built-in flashlight is a great tool. A few third-party apps make it a whole lot better. For instance, there's a really handy app you can download called 'FlashLight' that uses your phone's proximity sensor to light up automatically. This is especially useful when you need to constantly switch the light on and off and your hands are occupied or too busy to just keep going to settings. With the 'FlashLight' app, you simply have to place your iPhone face down on a surface (your hand will do) to turn it off, then just pick it up and it will automatically switch on.
Adjust the Brightness as You Please
While models before the iPhone 6s are capable of adjusting the flashlight's colour temperature based on the brightness of the room, it doesn't exactly allow you to choose the degree of brightness yourself. However, for the latest iPhone models, namely the iPhone 6s and up, you are free to adust it to your liking. Using 3D Touch, you just press on the iPhone flashlight icon long enough to choose from Bright Light, Medium Light or Low Light.
Master the iPhone Flash Do's and Don'ts
I think we can all agree that the flash is our favourite go to tool when it comes to night-time photography. But while it has come to our rescue countless times in low light scenes, there are instances where it does more damage than good. Take the classic red-eye scenario for example. Just when you thought the iPhone flash has you covered, you lay eyes on a perfectly angled photo of your favourite band, all smiles standing right next to you and your red eye. Thankfully you can now correct this your favourite editing app. Still horrifying though.
So here's the general rule: stay away from your iPhone's flash if your subject is more than 6 feet away. The iPhone flash works best within close quarters, so keep that in mind when you're at a large venue. Instead of enabling your iPhone's flash, you can simply resort to HDR, which is your best bet at low-light conditions and huge spaces.
You probably also know that you should never use your phone's flash when taking a mirror shot. This will only create a ball of light somewhere in your photo (most of the time on your face). The same applies when you're taking a photo near a glass door, a window, a laptop, computer or TV. So do yourself a favour and just turn the flash off.
The iPhone flash is an undeniably useful tool. Unfortunately, its capabilities are not fully enjoyed by many. Try some of these tips and you'll see that there's so much more to the iPhone flash than meets the eye.
