Not wanting to jump on Zakd's post, but having a couple questions myself..

I have a set of Alien Bee's , recommended here, and I must say I very much like them. But question one is, would there be an advantage to not using the reflector when using an umbrella? So far I have allways had the reflector on, but just got to wondering about this recently and thought I would get your oppinions.

And question 2, how far in or out should I slide the umbrella into the mount on the flash unit? Is there a rule of thumb, or just about anywhere works?

Thanks

Meiko,

Question #2: I believe I read somewhere that placing your umbrellas close to your light source will generate "harsher", more concentrated lighting. Moving the umbrella away from your light source requires more power, but gives a less harsh, more dispersed (i.e. even) lighting pattern. And, moving the umbrella farther away from the light source provides broader lighting, illuminating a larger area.

Actually, that's backwards...the closer your light source, the softer the effect (because it causes the light to "wrap" around your subject better...of course, you don't want to do this at full power and you want a large a light source as possible.

As far as using the reflector on the flash unit, I never use one on my fill light (try googling bare-bulb flash). It gives much more dispersed light (hard to describe...try it both ways and you'll see the difference). (The shot below was done this way...fill was a white 60" photogentic umbrella about 3ft from the model & a bare bulb Norman head at 1/2 stop less than my main, plus a rear hair light).

How far you insert your umbrella through the holder is dictated by how close you are placing the umbrella to the subject...personally, I don't want a model poking her eye out with the end of my umbrella...YMMV ;-)
