Sometimes it can be simple: off-camera flash can be really easy. Like in this student’s recent portrait:
You can also see how nice the splash of colour is in the background, right?
A matter of choosing manual mode with just the right combination of aperture and shutter speed and ISO to get enough light into the background. And Flash White Balance makes the tungsten light look nice and orange.
My message today: although flash can be done in a very sophisticated manner, it is not always necessary to make it complicated. Often, very simple is all you need. “Off camera” is often enough to just make it work. And an off-camera flash cable, while not cheap, is the simplest way to achieve this.
