颠覆性相机即将登场

    在过去的10年里，数码相机的像素越来越高。在摄影界，最新的创新当属Lytro公司即将推出的光场相机，它使用户可以在完成照片拍摄之后再对照片进行对焦。在《财富》科技头脑风暴科技大会上，Lytro的创始人兼首席执官吴仁（译音）展示了这款相机，并介绍了它的原理：相机里有一个小型传感器，可以记录下比传统相机更多的光束。这些额外信息被存储在每张照片的影像档案里，哪怕时间过了很久，用户仍然可以调整照片的焦距。该公司表示，今年晚些时候，该公司会面向消费者推出一款“价格有竞争力的”的相机。谁会买这样的相机呢？星巴克（Starbucks）的首席信息官史蒂芬•吉列特也许会就买一台。他在看了吴仁的展示后，在Twitter上写道：“新的Lytro相机非常具有颠覆性，它将导致相机公司陷入严重的‘创新者困境’”。

Camera ready

    Cramming more and more megapixels into digital cameras is so last-decade. The latest innovation in the world of photography is Lytro's upcoming light field camera, which lets users focus a picture after it's been taken. In a demonstration at Brainstorm Tech, founder and CEO Ren Ng shows how it works: A tiny sensor records more light beams than conventional cameras. The extra information, saved in each image file, allows photographers to tweak their shot long after the "Kodak moment" has passed. The company says it will come out with a "competitively priced" camera for the consumer later this year. Who'll buy one? Perhaps Starbucks CIO Stephen Gillett, who, after seeing Ng's demo, tweeted, "New Lytro camera is so disruptive it is going to cause major 'innovator's dilemma' headaches for camera companies."
