Headshots

So, one my friends is an actress and she is needing some new headshots. She asked me to shoot her, which I was thrilled to do for her but I started to look some stuff up on how to shoot it. I've been around theater and that seen, but as a photographer I have never shot headshots before.
Here is a good website, really for actors, but it also is pretty interesting and gives some good tips. Check it out!
