The camera in your iPhone can do more than just take pictures. You can also use it as a magnifier. So it’s easier to do things like reading small text in a newspaper, or getting a closer look at that spider crawling up your leg (you know, instead of running away from it).

Tap 
to apply different color filters. You can adjust the brightness and contrast of the filter by dragging the sliders below the filter. And to invert the colors of the filter, tap
