2 400FX or 1 1200FX?

<p>I am trying to get some recommendations as to what set up I should purchase. I started of with Elinchrom 400FX set (2 lights, umbrellas, softbox, etc.). After a little while, I realized I need a third light as more light is needed for the background, especially for high-key shots. My question is whether you would recommend me to get another 400FX set (with two lights) or one 1200FX with a huge sift box.<br>

I mainly shoot portraits (sometimes full body) with 1 to 4 people.<br>

Thank you in advance.</p>

<p>Well, I think a 1200FX would to much for a third light, but depends on the dimension of your studio</p>
