A San Francisco-based wedding photographer recently captured a couple’s happy day in a very unusual way – with an iPhone 4S.

Kim A. Thomas, the photographer in question, was specifically asked to use a cameraphone by tsoon-to-be-married couple Jonathan and Brandi.

Thomas, who has confessed to being more used to using a Canon 5D, used an arsenal of accessories to augment the performance of her iPhone. These included a phone case that allows an SLR lens to be mounted to the smartphone, and a full-size tripod for stability. Photo-sharing app Instagram was almost exclusively used for editing.

The event took place at San Francisco’s City Hall, the same venue which once hosted the wedding of Hollywood star Marilyn Monroe baseball legend Joe DiMaggio.

In a blog post on her website, Thomas says that although she often uses her iPhone for photography, this was an unusual request: “I’m a huge Instagram user and take more photos with my iPhone than any other camera I have.

“It’s the camera, er, phone, I always have on me, and it’s what has documented some of my best memories”..

Whilst some of the resulting images are a little low in contrast and could perhaps have done with a touch more editing, it is nothing that couldn’t have been done on the phone itself. Although it seems that smartphones are unlikely to replace high-spec DSLRs for this sort of occasion, it must be said that this is an excellent way of showing the results which they can produce.
