How do you prep before shooting someone? Do you ever get nervous?

Unless its like a impromptu shoot I prep by going over the looks that Julie designed, going over my plan for the lighting, background and space.

I kind of then spend the time loading all my cameras to get my thoughts in a row.

However, once I start shooting I have those guides in mind but really hand it all over the model, and what happens live in the moment. I believe that if you try to stick to a structure 100%, at least for me, you end up missing the magic of the moment.

I never get nervous anymore but I use to. Now I just enjoy it so much Im like a kid in a candy store running around switching cameras like mad.
