SLR Lounge has a nice introductory tutorial about lighting. It’s part of a course for which you have to pay a fee, but the first segment is free and has some useful information.
If you’ve ever attended a full-length portrait lighting seminar/course (like NEIPP’s), you would know that there’s much more to lighting than these five patterns. You have hairlight, background lights, and fill lights. There is also high-key lighting, beauty lighting, and a lot more. But, SLR Lounge has a nice start here.
