Wireless E-TTL
     
Overview
Easy to Setup and Use

For years, wireless flash was considered a technique reserved for experienced, high-end users. But with the incredible surge in interest in the field in recent years, many �light� advanced amateurs and even casual shooters are beginning to see wireless flash as a tool for changing the look of their photographs.

Until now, it has required a bit of understanding of the exact process to set up wireless flashes, and an understanding of things like lighting ratios to truly take advantage of them. But with Canon's recent introduction of the EOS Rebel T3i (and its �EasyWireless� option) and the affordable Speedlites 270EX II and 320EX, there is a new-found realization that it doesn't have to be complex.

The Typical User:

Wireless E-TTL was traditionally aimed at high-end users such as professionals and advanced amateurs. However, Wireless E-TTL may also be of interest to:

  • Professionals who are not experienced photographers:
    • Real estate salespeople
    • Corporate users who need to document people and events
    • Law enforcement officials who need to accurately and professionally document accidents, crime scenes, and other evidence

An understanding of how Wireless E-TTL works and the ability to simplify and explain it will make it possible to open the eyes of prospective buyers to the possibilities of this technology, hopefully stimulating sales of flashes and even third-party gear used to
modify lighting.
