Over recent days, pet owners have been seen using their iPhones in an unusual way: capturing 360-degree photos of their pets, seemingly to check for bugs. This intriguing method, discovered by users on Xiaohongshu, involves using the iPhone’s built-in magnifier and invert filter to highlight potential parasites on pets. By searching for “Magnifier” on the iPhone and selecting “Invert” under the filter options, users can take photos where bugs appear unusually bright against the pet’s fur. This technique is especially useful for pets that react poorly to traditional deworming methods or frequently venture into grassy areas. Android phones, like those from OPPO or vivo, offer a similar function by enabling the invert mode in settings.
This newfound use has sparked widespread interest among pet owners, turning into a trending topic on social media. While some users have humorously experimented with this feature on their colleagues, others have explored its potential for checking banknotes or detecting hidden cameras. However, experts caution that while these methods can be entertaining and occasionally practical, they should not replace professional tools and expertise when necessary.
