Techniques for updating zoom properties of corresponding salient objects are described that support parallel zooming for image comparison. In an implementation, a zoom input is received involving a salient object in a digital image in a user interface. An identification module identifies the salient object in the digital image and zoom properties for the salient object. A detection module identifies a corresponding salient object in at least one additional digital image and zoom properties for the corresponding salient object in the at least one additional digital image. An adjustment module then updates the zoom properties for the corresponding salient object in the at least one additional digital image based on the zoom properties for the salient object in the digital image.

Described methods and systems for achieving an optical bokeh effect by a camera supporting a computing device, such as a laptop computer. A measurement is performed as to focus spot position of a subject. The depth of field (DOF) of camera lens is determined. An offset as to the focus spot position is calculated such the background of the subject would be blurred to increase the optical bokeh effect. The offset is added to the focus spot position or to be more in focus to decrease optical bokeh in the background, to arrive at a focus spot position that supports the optical bokeh effect. The camera lens is adjusted for the new focus spot position.
