In order to achieve the exposure you want with ease, you need to get a feel for the luminous power of the particular light sources that are in play when you are shooting. I think this comes pretty easy once you have a look at the numbers because then you see that there are worlds of power between the various kind of light sources, even though our naked eye would not signal us so much of a difference.

For reference:

2. The BTS video of the shoot: http://youtu.be/Ph5j8i9iTp4 (Kind of SFW YouTube version)

Having a streamlined workflow frees you up to spend your time shooting awesome photos rather than caring about the postproduction work that piles up, juggling disks for all the data, or thinking about excuses you can send to your client because you don't have the final edits for them yet.
