“Besides more conventional usage of the iPhone for street photography, one of the things I like the most in iPhoneography is [to] try to experiment with the apps to create effects [that] they weren’t meant to do.
“And none other works better for this than being able to achieve one of the common features from Lo-Mo cameras, or even Polaroids: A double or multiple exposure.
“To create one on the iPhone, there are different paths you can follow: You can either go straight to an app like Backgroundz that combines two images of your choice, or you could use some of the very complex apps, like Iris, to layer images and play with the opacity as one would do in Photoshop.
“But there are other more challenging (yet satisfying ways) to get there, and those are my favorites. On one hand, you can go to an app like Autostitch, which was meant to create a panoramic image by combining previous sequenced photographs of the same landscape or spot. But if you happen to have, let’s say, two or three different characters in the same background, and you try to compose the panorama with those images, sometimes the app will deliver a mash up resulting in a creative, ghostly looking double exposure shot. It’s not always guaranteed, but it’s fun to check if it will.
“Finally, you can get to the most reliable (and unexpected) use of one app to achieve another result than its original purpose: Pro HDR app. In that one, you have the options to shoot an automatic or manual HDR shot, or you can select two images from your library to melt [together]. In theory, you would select two images of the same subject: the darker one first, where the highlights are well exposed, and then the lighter one, where the shadows are brought to life. But instead, you will choose two images you want to mash together to create a double exposure. Just know that the one you choose [second] (the lighter one) will have more predominance in the final mix.
“In Pro HDR, once you get the combined image, you can still fine tune it with controls over brightness, contrast, saturation, temperature and tint. Save it to the library, and perfect job. You can see an example with Pro HDR. The photo above, called ‘Let the Right One In,’ [was] created by combining two black-and-white Hipstamatic photos. Sion Fullana
