Refocusing lets you adjust the focus of your photos after you capture them!

Inspired by a homework assignment for students in a computer vision class, the Refocusing app allows you to combine multiple images in one “large aperture” image in which you can choose which part of the scene is in focus. Give your iPhone camera SLR-like powers.

How to Use Refocusing:
1. Frame your subject, press the red capture button, and SLIGHTLY JITTER THE CAMERA location while several images are being captured. In most cases, the natural shake of your hand is enough.
2. After images have been captured, TAP ANYWHERE in the image TO RE-FOCUS the scene at that point. The results will be most satisfying in those areas of the image that have interesting features for the algorithm to detect.
3. Press "Save" to SAVE the currently re-focused image to your camera roll.

Technical Specs:
Photos are saved to the camera roll at 1280x720 resolution.

Customer Reviews

It really works!

Bad focus is the number one reason I have to throw away images from my iPhone. Focus is also one of the biggest challenges for these little cameras — it’s hard to tell on that little screen if you’re focused. I envision using this in situations where I really want to capture “the” image in a time compressed situation. I’ve tried it in several scenarios — mostly low light so far, and had it work well. Wish: Save several shots so I can revisit them and play around with them.

Works as advertised!

Works great! The key is not to move too much while capturing, as the quality of the “blur” is related to how you move the iPhone in the capture phase. I found that just not actively trying to “steady” the phone produced enough jitter to create very nice blurry backgrounds. Very nice!

Have to power-cycle the iPhone 4S

Other than that, it works as advertised. Impressive! If the developers go forward, I’d want a zoom function in the refocusing window. But nicely done!
