Thanks for the feedback! I have mixed emotions about using one. I can see where it would be beneficial, but I also agree with the comment just above ("The thing is I always nail my exposure in one or two test shots."). I would suggest that dong this probably takes less time than setting up using a light meter.
The reason why I asked is because, although I am not new to photography, I am new to making a business of it and I want to get into portraiture. This could be a type of work in which a meter would be beneficial, but then there the "...one or tow test shots" thing. Anyway, I posted something in a LinkedIn forum about doing this kind of work and asking for lighting suggestions, and this one guy gave me all kinds of sh@#, suggesting that "Just because you bought a bunch of stuff and now you want to take portraits does not make you a professional photographer." Well to that I say, no kidding. He also went on to say that since I am participating in a Pro Photo group that I should already know that I need a light meter. For one, thing I think he has some nerve getting in my face like that, and how does he know whether or not I even have one? All I asked about was the kind of lighting to use: Speedlites or strobes (Alien Bees, et. al.).
Anyway, Like I said, I can see where in some cases a meter would be beneficial, but I can also see it laying around collecting dust too.
Thanks again everyone.
