I saw a link to this free webinar series over at CreativeTechs.com for a Portrait Lighting A to Z course run by photographer Rosanne Olson. All seems legit, presumably they are offering it in the hope you'll sign up to other courses but there's no obligation to.
The course starts on Wednesday 13th of January and runs for 5 weeks on a weekly basis, here's the link: http://creativetechs.com/training/lighting-course/
There is also a video where she talks about her photographic experiences and gives a brief course overview here: http://creativetechs.com/training/rosanne-olson-overview/
Looks good to me, I'm in!
