Panorama photographs on iPhone

By John Nayler


It is amazing that you can now make panoramic photos as part of the IOS 6 release. iPhone 4 started the series of iPhones that had the quality of camera and optics to take good photos. iPhone 4s moved it up a notch with the resolution and lens quality receiving a major upgrade. iPhone 5 is even better. With this quality the era of the pocket digital camera is on the way out, as the iPhone and other smart phones are making it easy to grab great photos and share them instantly.

Apps have been available for ages that do cylindrical and spherical photos. Microsoft Photosynth is possibly the best app for iPhone panoramas as it makes full spherical panoramas.

There is one big problem with all these apps. If you don't keep the camera lens in exactly the same position as you make the photos you will get parallax error. Objects at the edge of the photo will appear different in each of the photos. The app then has to make sense of the photos. In most cases it will distort the joins or make mistakes that appear ugly.

The problem of parallax has plagued photographic professionals for years, and they go to great lengths to fix it. The same problem of parallax has been solved on iPhones much simpler and with much less expense.

Photographers that look for the best result from panoramas spend a lot of time and money on systems that ensure their SLR camera is properly positioned. The system they must use is heavy too and the until they process the photos they won't know if they got it right. The processing time and set up time for a photographer required a high cost, making it impossible for small business or high volume / low cost models to apply. It was simply to hard to get a business result in the past, and this kept the technology at arms reach for most businesses. The amount of this style of photography found online was minimal.
