5 cool things to do with smartphone camera other than taking photos

1.Your smartphone can help you see infrared radiation!

 Our eyes can't see it, but digital cameras surely can. A smartphone's camera is indeed sensitive to IR radiation, and if you want to try it for yourself, just use a common IR remote control. The infrared beam emitted when a button is pressed will show as white or purple light in the viewfinder of your camera app. There are not much uses to it but you can use it to check if your remote batteries are dead.

 2.As a mini microscope

 Holding about any cheap lens in front of the camera will help us get more magnified images. You can even try it using a water drop on the camera’s lens (although I cannot attest to your camera’s waterproofness, so I do not suggest trying it). However, you can use anything from a magnifying glass, the optical lens from an old CD player, or even the contact lens cases with the magnifying glass on the lids.

 3.Make many copies of you without any Photoshop!

 Using the panorama effect, you can also use it to make clones of yourself. Let another person do a slow pan across a field of vision while you run behind them after they shoot you and back to the other side of the frame. Then repeat.

 4.Detect Health Problems

 You would've heard about the “Red Eye Effect” where pupils appear red in photographs of eyes. This is caused by light reflecting off the eye’s retina, making the eyes appear red. However, sometimes only one eye appears red, and the other eye appears white. This is a symptom to many diseases including melanoma and retinoblastoma - very dangerous cancers. There has been research into other devicesthat connect to your cell phone that can also detect cancers, malaria, and diabetes from your breath; test water quality for pathogens; and monitor lung function in patients.

 5.Your Phone's Camera Can See Your Blood Pulsing Through Your Skin!

 There are lots of great fitness trackers out there, and many phones are beginning to incorporate trackers directly into the hardware. But say you don't happen to own a tracker and you want to check your pulse rate. The developers behind apps like 'Instant Heart Rate' (available for iOS, Android, and Windows) claim they can read your heart rate through your device's camera. Just place your finger in front of the camera and the app monitors the slight changes in skin color as blood pumps through your finger and then calculates your pulse. If holding your finger against your phone's camera seems like too much work, the 'Cardiio'(iOS) app claims it can use your phone's camera to read your pulse just by monitoring the minute changes of color in your face!
