I am slow and dense. This is how I learned lighting. Maybe it will help you.

Load your favorite character. Turn on Ground. Delete all but one of the lights. Turn it into a spotlight (white to start). Use Point At function to aim it at the head of your figure. Select the light and start at the top of the dials, seeing how each affects the lighting. If you want a more distinct display of the effects, set a vertical plane (medium or dark color) in the middle of your scene.

Except that you have to move the light more leftward and back than you would expect, the Poser light moves are pretty straight forward. (Be sure you have Cast Shadows and Anti-alias set on Render Options).

When you feel like you have the single spot nailed, and are tired of the "dark side of the moon" effect in the shadowed areas, make a new light (blue is good), change it to infinite, turn off Cast Shadows, and crank down the intensity to 50% to start. Move it opposite the original spotlight and aim it somewhere lower on the figure to fill in the shadowed portions and make them more visible.

Then....

Add in a sphere from Prop Types and resize it to 10%, setting it back (z trans) to -5 to start with. Fire up the Depth Cue and go make yourself a nice cup of tea. Then play around with moving the ball, rendering, repeat, until the many mysteries of "too much fog", "too little light" are revealed to you.

When you have these three elements under your belt, you will pretty much have a handle on Poser lighting.

There are all kinds of fancy things to add after that, of course, but you'll have some idea of how to control the effect.

And, you might consider that language is managed on the other hemisphere of the brain from artistry and mathematics and music, so it only stands to reason that for the truly artistic, words, as a whole, are a "second language."

Myself, being a less-artistic left-brainer, find the spelling in this forum to be one of its main delights.
