Tuning your built in camera
There are three options on the market right now that till allow you to ‘tune’ your iPhone camera via add on lenses. This is the review of one that is a snug protective case from Griffin that has a lens allowing the iPhone to take close up picture clearly.
Your first reaction may be that you don’t ‘need’ to take close up pictures. But, you may want to take a closer look at how your using your camera now.
For group shots or pictures of landscape, all is good. Try to take a picture of a piece of paper or a scratch on your car and you get a slightly out-of-focus usable-ish picture.
