I've started using a simple LED panel to light some subjects - filling in light with a given color based on whatever I'm working with at the time. (Looks like a Promaster model 68B.)
After reading the article on common flash photography mistakes, I've started thinking about various missed opportunities I've had. Cases where just a little extra light would have filled in a void I could not compensate for in post.
Question: what is a good route to learn what is possible with flash that is portable. I tend to only use what I can carry in my backpack. Anything larger will not be used - ok, unlikely to be use. (The LED panel fits nicelly in the backpack.)
(Yea, I might be asking for the impossible. However, I know next to nothing about flash - other than what I've read here and other places.)
