Capturing images of active subjects according to activity profiles

Techniques for capture of images of active subjects are described herein. In one or more implementations, a wearable device is configured to collect data regarding action of a subject associated with the wearable device during an activity. The wearable device then communicates with a user's mobile phone or other computing device to trigger image capture in accordance with trigger points defined for the activity. This may involve streaming collected data for processing by the capturing computing device to recognize the triggers and/or sending indications of trigger points that are recognized by the wearable device.
