Computational photography can change your lens?
1

So Ive been playing around with the cameras in NOMO, an awesome app that simulates classic analog cameras. Most apps will just add filters or effects, this app is actually changing the field of view of the iPhone lens. As you can see from the EXIF data, this app uses the iPhones main camera which is the 26mm wide angle lens. Im standing in the same spot for all these shots, how is it able to change the field of view of the same lens to make it look like Im shooting with completely different cameras and lenses? Make sure to click on each one to see them full sized.

I tried to recreate the same field of view of some of these with the iPhones 3 lenses in the stock camera app and I couldn't do it. Especially the wide and medium format simulations, the depth and the compression of the photo changes. Most of these also give you full manual control over ISO, shutter speed and even a few have aperture settings. Most also have exposure compensation dials. Its awesome to have a pretty realistic simulation of almost 50 different cameras in your pocket and this is just a glimpse of what computational photography is capable of.

Hasselblad 503CW

Hasselblad XPan with Kodak Ecktacrome E100VS reverse film.

Another example of how the compression in the photo changes based on which camera you are using.
