Instead, the hack advises you to hold your phone farther away from your face and zoom in, to get a more accurate, better-looking selfie. Men who want to emphasize a stronger chin or chiseled jaw, for instance, could position the camera a certain way up close. Makeup artists like Snitchery and James Charles are promoting a 'selfie hack' that suggests taking up-close photos with an iPhone front camera distorts your facial features. Similar formulas can be created for other facial features as well, Paskhover said. Photographers have known this for decades.” you to place a lens on your front and rear-facing cameras at the same time. “That’s a classic portrait distance, which is fascinating. Attaching an Olloclip lens over your phones existing camera dramatically. “At that standard portrait distance of five feet, everything evens off,” Paskhover said. This lookup table has 42 values and the interpretation of this lookup table is explained clearly Apple's documentation and in AVCameraCalibrationData.h.
These lens distortion coefficients are stored in the AVCameraCalibrationData class's lensDistortionLookupTable instance. At five feet, however, the proportion of features is to real-life scale. iOS provides lens distortion information for images obtained with the iPhone depth cameras, specifically the front-facing TrueDepth camera and the rear-facing Portrait mode camera. At 12 inches away, for instance, selfies increased nasal size by 30 percent in males and 29 percent in females. They found that the perceived nasal width increased as the camera moved closer to the face. In a recent study, they calculated distortion of facial features at different camera distances and angles. And it only had a rear camera there wasnt even a front-facing selfie shooter. Paskhover and colleagues explain in JAMA Facial Plastic Surgery that the distortion happens in selfies because the face is such a short distance from the camera lens. The camera on the first iPhone way back in 2007 was a mere 2 megapixels.
