Zooming to Faces Depicted in Images

Methods, systems, and apparatus, including computer programs encoded on computer storage media, are described for zooming into a portion of an image that is associated with a specified feature, for example, a portion of an image that depicts a human or an animal face. In one aspect, the subject matter described in this specification can be embodied in methods that include the actions of receiving user input requesting to zoom to faces depicted in one or more digital images, where the faces include either human faces or animal faces. Additionally, in response to said receiving the user input and for each of the one or more digital images, the methods include the actions of presenting a zoomed view of the digital image that shows an instance of a face depicted in the digital image, such that the zoomed view is presented at a zoom-level that is selected (i) to be less than or equal to a predetermined zoom-level and (ii) to maximize a fraction occupied by the depicted instance of the face within the zoomed view of the digital image.
