Light Modifier Characteristics?

<p>I am considering taking the plunge on some Alien Bees lights. I have decided that what I “need” (read; can afford) is a set of two B800. My real confusion is over light modifiers, because there are so many different types such as umbrellas, softboxes, beauty-dishes, etc. and each in different sizes and styles with or without grids or other attachments etc, etc. Maybe there is a tutorial on this somewhere that I haven't found yet.<br>

Now, I know that the standard reply to “what should I buy” is “it depends on what you shoot”. While I am sure that this statement is true, it is also not very helpful in making a decision. What I am really looking for is some advice on the <em>characteristics</em> of the light that will be produced by the different types of modifiers, and what kind of modifier may be more useful and/or less useful for various situations.<br>

I expect that my most of my shooting, at least near-term, will be single-subject portraits, small groups and perhaps some fashion shoots, all on location rather than in a dedicated studio. Some of these may be in small settings where there just won’t be enough room to open an enormous modifier. I already have two 45-in white umbrellas with removable backing that I have used for a while with speedlights, but I think that some of these results have been a little “hard” and I'd like a softer effect. I am attracted to the Buff “PLM” system, maybe the 64-in size, because with its various attachments it sounds quite versatile and relatively inexpensive.<br>

Given the vast store of knowledge in this most excellent community of fine photographers; if you were in my situation, what would you do, and why?<br>

Thanks</p>

<p>I can't advise you on which light shapers you should buy, because it really does depend on so many different factors, including skill levels, the subject and the effect that the photographer wants to achieve.<br>

Typically, beginners start off with umbrellas (often with hotshoe flashes) and as their skills increase they usually move on to studio flash, and then to increasingly hard light sources, to bring out the best in their subjects.<br>

As for a tutorial, look at <a href="http://www.lencarta.com/2009121893/light-shaping-tools-compared/index.php">this one</a> on the Lencarta website. The 'model' here was a mannequin simply because 'she' was more compliant than a real person and therefore could be in exactly the same position each time. The downside of this is that plastic skin doesn't behave in exactly the same way as human skin, and the eyes are painted so don't show catchlights. But I think it will help you.</p>

<p>You'll be wanting at least one large softbox. Get the Buff/Bees folding variety, so that you can buy their optional grid later, if you want it. That will provide a substantially different quality of light than will an umbrella or beauty dish. <br /><br />Even though it's a different manufacturer showing off a different mix of products, you might consider poking around in the free lessons they provide at the <strong><a href="http://www.photoflexlightingschool.com/Lighting_Lessons/index.html">Photoflex Lighting School site</a></strong>. Not so much because they're showing off a particular thing that will exactly answer your question, but because they provide a lot of set shots that let you see the modifers (softboxes, umbrellas, scrims, etc) in use, and the resulting light on the subjects. It can help you to visualize similar modifiers in your own circumstances.</p>

<p>Thank you for this information. I found the Lencarta article especially useful because it shows side-by-side examples of several different types of modifiers under similar conditions. <br>

Thanks</p>
