App Turns iPhone into a Smarter Camera

Tutorial   SynthCam

The cameras in most mobile phones are an afterthought. This has left an opening for programmers to step in and develop software to make the images produced by smart phones much better.Now Stanford professor Marc Levoy has created an app that changes what the iPhone's camera is capable of.

SynthCam software lets the iPhone 4 take pictures that look like they were taken with a larger, more expensive camera.



Cell phones have a small aperture, hence a large depth of field. In other words, most of the scene is in focus at once.  However, if you record video while moving the phone slightly, and you add the frames of the video together, you can simulate the large aperture of an SLR. This app lets you do that.

Adding together many frames has a side benefit; it gathers more light. Thus, pictures you take with this app will be less noisy than pictures taken with the iPhone's native Camera app.  The app allows you to do many other things, like see through bushes, remove moving people or cars, blur flowing water, and simulate a tilt-shift lens, but let's not get ahead of ourselves.  Try the app!
