Elizabeth Westhoff, the Archdiocese of St. Louis' Director of Marketing, wrote an excellent article summarizing the many ways she and others in St. Louis are using iPhones and a shoestring budget to promote the faith through video, pictures, social media, etc.
I love this section:
The production of each of these videos is something unseen in most other archdioceses across the country and for those of us who have been involved in their production; it has been a complete labor of love with an understanding that it is yet another way of getting out the messages of Christ.
One of the most amazing things we have been able to do is to use our iPhones as recording equipment.
When one or two of us go out on these “simple” video shoots, I’m always afraid the people on the other side of the “camera” are thinking we’re not prepared, or professionals, or something else along those lines. We show up with a tripod, lights from Home Depot, a battery-operated microphone, an iPhone and nothing else. We have everything we need, really.
