How to Use iPhone Magnifier Camera
iPhone as Magnifying Glass?
The latest versions of iOS for iPhone include an excellent Magnifier feature which can turn the iPhone camera and screen into a magnifying glass. (Note the iPhone Magnifier is completely different from the photography related features of iPhone camera, as it’s not intended to take pictures with. When you tap the camera button it does not actually save the picture, it just freezes the magnified item on the screen so that you can focus on it, read it, zoom, pan, or adjust was needed.)
