Have you ever tried to get in extremely close to photograph something, maybe a detail or interesting texture? The iPhone camera does allow you to focus fairly close but what if you wanted to get in even closer?
There are actually a variety of lenses out there that attach to your camera and will allow you to do more with your iPhone! Companies like photojojo and phocus offer fairly inexpensive lens kits that have a range of macro, wide angle and telephoto lenses to expand your creative vision. To use the lens, simply attach it to your camera and for the most part shoot as you normally would.
One thing you have to consider when shooting very close up is something called the “depth of field.” Depth of Field is the range of sharpness in a photograph which gets smaller as you get closer to your subject. When shooting very close up like you will be with a macro lens, your depth of field, which is normally fairly great becomes very shallow. Sometimes your image might only have ¼ inch of sharp focus in the frame so make sure you are focusing where you want in the image. Shallow depth of field actually makes for some very interesting and creative photographs, so have fun with the technique!
