Zoom

Zoom is the one Luff control I don’t recommend using. iPhones don’t have true optical zoom (the focal length of the lens is fixed), so when you “zoom,” you’re not optically magnifying the view, all you’re doing is cropping the image, which you could do later in post-processing if you really wanted to. This kind of “digital zoom” diminishes your resolution, which can significantly reduce the image quality of your pictures.

But if you want to try it, tap on the magnifying glass icon at the top left of screen, and then move your finger rightward to zoom in (slide your finger over the +/- status bar, or directly over the image). To reset the zoom, slide your finger to the left, until it says “1.00x” under the magnifying glass icon. Note: the zoom control doesn’t have an “M/A” toggle control like the other three controls do.
