Thanks, Hoogle, but we obviously have very different likes and dislikes when it comes to teaching a subject like this.
When I tuned into that broadcast, she was in the middle of a long repetitive schtick to the effect, "if it looks good, it's fine", and was discussing 30 degree gridded beauty dishes like everyone has a few just laying around. Hopefully, there was an earlier part where she discussed the basics of lighting, but I couldn't see any way to immediately get back to the beginning.
IMHO, the "if it looks good, it's ok" approach is great for photographers who have already developed their ability to "see" the various aspects of a real-world lighting situation, and already know how to change things around to get what they want.
However, <IMHO>, if a noob doesn't at least know the basics, they will flail around much longer than if they at least know the names and functions of the usual lights, know a bit about light modifiers, know how light falls off with distance at different rates depending on the source/modifier, and at least know the most common looks one can achieve (eg, butterfly, short, Hollywood, etc.).
To me, a very close analogy to her approach might be telling a Photoshop noob who dropped by PSG asking about a logo that they like, and someone tells them to just try the different tools and play around with them until they reproduce the effect they like. And, we then find out they don't even know how to crop a picture and the only program they ever used was Microsoft Paint. :-(
Of course, there is no one way to light a portrait, or light a scene, and your technique must always be a servant to your goals, but one has to walk before they can run in all things in life.
When I get some time, I'll poke around and find some tutorials more in the style I suggest.
Best regards,
Tom
