A lot of the time, you will see professionals use two- or three-light setups for portraiture, but you might be surprised by the professional results you can get from just a single light. This fantastic video tutorial will show you how to master both the technical and creative aspects of a single-light setup for portraiture.
Coming to you from Daniel Norton with Adorama TV, this excellent video tutorial will show you the ins and outs of single-light portraiture. I am a big advocate of sticking to single-light setups when you are first learning how to light. A lot of the learning process is simply gaining an intuitive understanding of things like relative source size, fall-off, and more, and these can be much more difficult to grasp when working with more complicated setups. Once you have those mastered, you will find it far easier to embrace multi-light designs. Beyond that, single-light setups are a fantastic choice for a wide range of scenarios, particularly for something like on-location work where time is at a premium. Check out the video above for a lot of helpful info from Norton.
