Abstract

A system embodiment may include at least one camera wearable, at least in part, by a human operator. The at least one camera may have, when enabled, at least one active field of view that may be captured by the at least one camera in response, at least in part, to image capture actuation by the human operator. This embodiment also may include a viewfinder wearable, at least in part, on a head of the human operator. The viewfinder may provide to the human operator, prior to the image capture actuation, at least one visual indication of the at least one active field of view of the at least one camera. The at least one visual indication may be displayed in at least one central field of vision of the human operator. Of course, many alternatives, modifications, and variations are possible without departing from this embodiment.
