YES! You only need to put the main camera over the lens.
The multiple camera phones have one main camera. Align the objective lens of the main photo camera on the DIPLE lens and use the phone as a microscope!
How can you recognize which one is the main camera? EASY! Cover, with your finger, or with anything else, each camera; when you cover only the main camera you will not see the previous image on your screen. When you cover a secondary camera, you will keep seeing the same image on your screen! On some iPhone models (i.g. iPhone X) the image may switch from the main camera to the secondary one, in particular when you apply digital zoom. For avoiding this annoying effect, the solution is locking the autofocus, once you are going to apply the digital zoom! How to do it? On the native camera app of IOS, as well as on our free app, it is very easy: just keep pressing on the screen for a while and you’ll get it done.
