Cameras in the near future will take photos that resemble those taken with smaller apertures, in other words, with more depth of field, but in substantially less time, using larger apertures and special software, thanks to work done by Google software engineer and computer scientist Sam Hasinoff . You see, Hasinoff is set to publish software next month that relies on his research on what he calls "Light-Efficient Photography" . Light-Efficient Photography is a solution to a well known photography problem in images where lots of depth of field is desired, smaller apertures have to be used. The problem is that smaller apertures necessitate longer exposure times, dramatically increasing the risk of camera shake and blurry images when using a camera minus a tripod. Hasinoff's solution is what macro photographers might recognize as a form of "focus stacking" , using two or more images taken with a bigger aperture, and thus faster exposure time, and combining the images in-camera via processing for an end result composite that happens faster in total time, and with the same visual depth of field, as an image taken with a smaller aperture. While the concept of focus stacking is hardly new, the idea of using the technique to improve image sharpness in-camera in a more consumer-friendly way certainly is. Similarly beneficial multi-shot composites are used in various Sony camera to aid in noise reduction or image quality, but not necessari ...
