I’m recovering from a stomach bug so here is a quick post with a simple setup.
I like to go back, experiment, and practice with just one single light aspect. That way, if and when I need to utilize that light aspect I will be ready. Alternatively, if the situation comes up where I am looking for a light technique to add to a setup, but I am not quite sure which one, experimenting like this keeps my mental library informed. After all, you can only use lighting techniques you know and only as effectively as you have practiced them and understand them.
That stated, this is obviously a single light setup. My light is equipped with a snoot to condense the light down to a small area. The snoot also has a yellow gel on it. When experimenting with light I make sure to have my subject do different poses to be sure I see how the light works with it with my own eyes. I get very familiar with it when I do the processing.
