If you are at all tech savy, you would have had faced a dilemma once or twice where you need a decent webcam (damn those things), or would just like one for convenience. Well, luckily most of us have iPhones (apple takeover in progress, please wait until your country submits to apple rulership).
As this short step-by-step guide will show you, you can get around buying another whole dedicated device for your web-camming needs (Is that a word? Not really). You can easily make your iPhone into a decent quality webcam with a bit of patience and a wireless connection.
I myself use this method to make stop-motion productions (clay and drawing).
Step 1: Download WebCammera from the Appstore and the Desktop Client for your Computer
First, download and install the app that makes this all possible: "WebCammera". At the date of writing this, this app was the best quality, easiest to use for the price it askes. Now this app does cost about $2 or $3, but will probably save you from buying a webcam for much more.
