Some low-key lighting practice work here. It is a style I enjoy playing around with though I am far from mastering this technique. In this setup I was using a single speed light aimed down. I used a snoot for some and no snoot for others. I also generally prefer this style in black and white, but I included a few in color.
The things to consider with low key lighting are obvious and not obvious at all. For starters, you have to consider shadow and light, those will be the two main factors in your photos. Where you put the shadows and where your put the light will impact how your picture connects with the person viewing it. But you also have to consider smaller details. For example: what color will you make the light? Or what background, even if lacks visibility, will you use. What clothing is involved? Seated or standing? Leaning forward or sitting back?
Low key lighting reduces what can be seen in the photo and in doing so it ups the importance or value of what can be seen and in doing so means you need to consider what is being seen when you are setting up your shot.
Anyway, in case I forget, Happy Thanksgiving tomorrow.
