Background lighting question

[Trisha418]

whats the best, but least expensive way to light a backdrop, or light a person from the back?

It depends on what you're using to light them from the front.

my interfits ex150

Well then you're going to want flash of some sort. To light the background with continuous lighting will require a very slow shutter speed to compete with the strobes and most likely be the wrong color temperature also.

Idealy, another interfit ex150 would be good. An economical alternative would be a cheap hotshoe flash like a Sunpak 383 plus an optical slave.

You might be able to make your 430EX work if you fire it with a hotshoe adapter plus PC cord or radio trigger system. No need to trigger the Interfits separately. They'll see the light from the 430EX and fire on their own.

Keep in mind each option has its own limitations in terms of power adjustment, available modifiers, recycle time, etc.

they are cheap and usefull.It's got a guide number of 20 feet, which will get you a distance of 1.8 feet at f/11. It has no power adjustment, and a wide 120 degree coverage angle that may spill into areas where you don't want it.

Those little slaves have their uses for accent lighting in interior shots & such, but I don't think it would be a very good tool for lighting a portrait background.
