Work in bright light. The extra optics lose light, so you don't want blurry shots from camera shake. An app like Gorillacam may help with hand-held photos. Mini-tripods are good too but they tie you down a bit with fast moving things like insects.



Make sure the magnifier is centrally positioned over the iPhone's lens, or you will risk cutting off the corners of your pictures. What you see is what you get.



There's no reason why any phone camera should not give similar results.



If you prefer to work single-handed, use Blu-Tak or simillar to fix magnifier temporarily.
