How can I maintain accurate WYSIWYG (what-you-see-is-what-you-get) modeling with the tracking feature if I am using units of varying total power (e.g. two B1600s with one B800)?
Your multi-light setup may include units of different output powers. If you use the supplied modeling lamp in each unit (the 150-watt lamp), the preview will not be accurate. A higher-powered model (the B1600, for example) at full power produces more light than a lower-powered model (the B800, for example) at full power. If you use identical modeling lamps in these two units however, they will be of equal brightness despite the output difference. An accurate preview can be accomplished by simply using modeling lamps whose wattage ratings are relative to the flash power. For example: In a setup using B1600s, B800s and B400s, you could use a 150-watt bulb in the B1600s, a 75-watt bulb in the B800s and a 40-watt bulb in the B400s. This will allow you to maintain an accurate WYSIWYG preview, reflecting the appropriate output differences between the models.
