>>4426792 (OP)This is seriously lighting 101 results that can be learned in an afternoon during your first day on a Sears portraiture job after the morning orientation spent 2 hours corporate brainwashing you and telling you not to sexually harass people.

>>4428388 are a cheatsheet but I'll do you one better: look up the strobist lessons. They're not even that in depth but practice them and you'll start to develop an intuitive sense of lighting.
Then watch Best of Dean Collins on Lighting for another approach, that defined a lot of the 90s commercial photography look as it was widely copied, but will be great practice that can be applied to modern looks, too.
Then read Roberto Valenzuela's books Picture Perfect Lighting and Picture Perfect Flash.
At some point along all of this, read Studio Anywhere by Nick Fancher, to learn how to do all of this minimally and affordably and spur creativity.
Do all of these, and I guarantee you'll be better than 99.9% of photographers, if not 99.99%, when it comes to lighting. You'll be able to recreate any retro look you want, be a master of modern lighting, and you'll be able to create original, effective lighting as well.
