1. I-Ttl Automatic Balanced Fill-Flash

Flash output level compensation using multiple flash units

In the Advanced Wireless Lighting mode, you can use more than one flash to

intentionally overexpose or underexpose various parts of the picture.

The series of photos below were taken with two flash units; the master flash unit was used on-camera to illuminate

the subject in the foreground, while the remote unit lit the background subject. The photo in the center was taken

without setting any exposure compensation on either flash unit, or in other words, 0.0 EV. Both the background

and foreground are correctly exposed. The photos reading across from left to right were made by using flash output

level compensation on the master flash that illuminates the foreground subject, in this case +1 EV compensation

for the left-hand shot and –1 EV compensation for the right-hand one. The pictures reading from top to bottom

were created by setting flash output level compensation on the remote flash that lights the background subject; the

top photo has +1 EV compensation and the bottom –1 EV compensation. (pp 54, 76)
