Sometimes, as much as we might hate it, we’re forced to stick a flash on the hotshoe. Perhaps it’s something not too important and we just want a bit more light on things. But maybe it’s something very important and you really need to not screw it up. Whatever the reason, getting great light out of an on-camera flash isn’t that difficult. There’s just one thing you need to think about.
In this video, photographer Neil van Niekerk explains that one important thing and how it affects your photos in very simple and easy to understand terms. Yes, I’m going to spoil it now, but that one thing is the inverse square law. But don’t worry, there’s no maths or charts here. Just a simple practical demonstration that’ll make it easy for you to get decent shots when using on-camera flash.
