I can not stress just how much i dislike on-camera flash and my devotion and absolute worship of low-light photography!

But I can't exactly remain in the realm of darkness.

So, first i ask for your understanding and patience, since i am not quite literate in studio equipment terminology!

Second, for those who had the experience, which would you think is better if any difference actually exists:

Studio Flash or constant light? I am looking for something that is not too expensive (not more than $400-$500) and somewhat portable ( not planning to use it outdoors )

Any help is more than welcome!
