The red ball used in cricket test matches is difficult to see when it's dark, even under lights. As such, cricket umpires often employ light meters not unlike those used by photographers to determine if the amount of available light is suitable for play. However, one cricket reporter tried to pass off something a bit strange as a light meter: the calculator app on his iPhone.
While talking about a match between South Africa and New Zealand that was apparently dealing with dark conditions, this cricket reporter held up a "light meter" to give his own measurement. There was only one problem: the light meter was the stock calculator app on his iPhone.
Sure enough, the reporter then doubled down, turning to "measure" the light from the other direction and obtaining (unsurprisingly) the same reading. People who watched the match have commented that it was no joke, as the studio commentator later called the reporter out for the ruse, but either way, it's a bizarre and hilarious attempt at bamboozling the audience, who might not know what the photographic device is otherwise. On a related note, you can also use the iOS light meter to help balance your checkbook should you need to do so.
