If you look at the work of the best studio photographers, you'll probably notice most of them use multiple lights to achieve their final results. And while there's certainly nothing wrong with that, you might be amazed at what you can accomplish with just one light, and this great video will show you every step in the process.
Coming to you from Michael Corsentino of Behind the Shutter, this excellent video shows the step-by-step process used to create these one-light headshots. When you're first starting out with lighting, I highly recommend you work with one light at a time, both because lights are expensive and because it's important to learn and understand the properties of artificial light before you start adding complicating factors. Corsentino's tutorial can go a long way in helping you understand these, as his method is built around a strong ability to read the light and modify it to better achieve the result he's going for. Once you master working with these modifiers and shaping the light to match your vision, you'll be much more ready to tackle multi-light setups with ease and confidence. Check out the video above for the full rundown on the method.
