Adobe shows off plenoptic lenses that let you refocus an image after it’s taken

Basically, a plenoptic lens is composed of a litany of tiny “sub-lenses,” which allow those precious photons you’re capturing to be recorded from multiple perspectives. The result is that you get a bunch more data in your image and an “infinite” depth of field, meaning you can toggle at what distance you want your image to be focused after the act of taking it.
