I didn't think that kind of professional photography was being done that way. Most of the Pro Photographers using iPhones are in News, Fashion, Art, and Commercial Photography. . . however, I think I see a way for you to make some money with an app. There should be a way to trigger study strobes via bluetooth or WIFI or even the flash on the iPhone. An App for that could be a real money maker. There are a lot of photographers out there that would pay for such an app. . . both iPhone and Android. (Well, not so much in Android, but you could make it Ad ware, there). Look into it. Photography Apps are one of the biggest sellers on the App Store.

Sometimes I absolutely HATE auto-correction. That should read “studio strobes”. . . SHEESH!
