1. A method for synchronizing a photographic lighting device to image acquisition by a camera, the method comprising:
- identifying a balance point of a light emission profile for a photographic lighting device associated with the camera;
determining a desired location for the balance point within an image acquisition window of the camera; and
determining a starting time of light emission initiation for the photographic lighting device, said determining a starting time of light emission initiation using the balance point to position the balance point at the desired location,wherein said determining the starting time of light emission initiation includes using the following relationships;
t1=tIAW*DLfactor
t2=TTBP−
t1 where t1 is a first amount of time from the start of the image acquisition window to the desired location, tIAW is the time of the image acquisition window, DLfactor is a factor based on the desired location, TTBP is the time to balance point from the time of light emission initiation, and t2 is a second amount of time prior to the start of the image acquisition window, the second amount of time being used to determine a location in time for light emission initiation to take place such that the balance point occurs at the desired location within the image acquisition window.

Abstract
A system and method for synchronizing a photographic lighting device to image acquisition by a camera using light emission profile information to position a light emission profile at a desired location in an image acquisition window. A light energy balance point of a light emission profile can be used to position the balance point at a desired location in an image acquisition window.
