I’ve found that the iPhone, and indeed many phone cameras, are actually pretty good at close focus photography, but if you really want to get up close and gross with some bugs or flowers or what have you, a macro lens is the only way. And as it turns out, you can use the lens that comes with a disposable camera just for that purpose. Of course, it’s not as simple as cutting and pasting the thing on there, but this Instructable will walk you through it.
