FocusTwist, from developer Arqball, is an app that allows iPhone users to take pictures with variable focus points. Photographs captured with the app use multi-image functionality to refocus specific areas in the snapshot, producing an end result that is similar to the refocusable images that can be created with the Lytro Light Field Camera.
To create a refocusable photograph, FocusTwist takes several different images of an object at once, each with a different focal point. Because the camera is capturing multiple photographs, the app requires a steady hand or a tripod to produce accurate results.
Capture and share images that can be refocused later!
Add a cool and fun dimension to your photographs and impress your friends and family.
Twists are great for food, toys, fashion, nature, architecture - any scene with multiple elements to focus on.
The developers suggest composing scenes with an object that is three to four inches away from the iPhone's camera and another object that is positioned further in the background for optimal results.
With multiple images captured, users can click through images to choose different focus points after an image has been taken. Focus shifting is done through the company's servers (which also compensate for shaking) and finished images can be shared with a link.
