FocusTwist brings Lytro-style imaging to iPhone
The new $2 app lets you refocus images after capturing them:
Unlike Lytro’s light field camera, which uses innovative new technology that actually captures entire scenes sharply in one shot, FocusTwist “fakes it.” The app doesn’t require any additional hardware because it’s simply based around the idea of stacking multiple photographs.
The app snaps multiple photographs of a scene with different focal planes and then merges them together into a single interactive image that can be refocused. One of the “secret sauces” behind the app is the image stabilization algorithm that it uses to cancel any hand shake that might be present when it shoots the multiple exposures.
What do you think—is the effect legitimately useful, or just a gimmick?
