When it comes to working with artificial lighting, there is sometimes the misconception that professional images require multiple sources, all of which are big, heavy, and expensive. That is not always the case, though. In fact, you can create professional-level shots with just a single speedlight, and this excellent video tutorial will take you through the entire process, from setting up the shot through post-processing.
Coming to you from Jiggie Alejandrino, this great video tutorial will show you how a wedding portrait was lit, shot, and edited. Besides proving that you do not need a complicated setup to produce worthwhile images, it is also good to learn how to work with artificial light by starting with a single source. Not only is this more affordable, it will allow you to more easily build an intuitive grasp of important concepts like source size, falloff, subject-to-source distance, and more. Once you are comfortable with these, you will find it much easier to design and build more complex multi-light setups. Check out the video above for the full rundown from Alejandrino.
