Selective Focus
One of the ways to pull your photographs out of the
ordinary is to adjust the focus over the image so that only some areas are in focus, and
others are blurred. This can be done in Photoshop or Elements, and there are lenses

both sharper and faster than the Original. All of the Lensbabies use aperture disks that
are inserted to use different f-stops. The and 3G start at , and the Original
starts at , one full stop slower.
Both the Original and focus by pressing in or pulling on the flexible lens housing.
The 3G is similar to the except that the three knobs lock the lens in its bent posi-
tion. This is a great feature if you are working on a tripod photographing still lifes. It
