This article will probably seem like a giant “duh” to a lot of you out there. Hell, even most avid selfie-shooters have figured this out. This is geared more towards the photographers who lust after huge, expensive light modifiers and overlook the amazing light source that is probably staring them in face. I suggest you start staring back!
Unless you’re locked in a basement, chances are you have at least one window. Maybe it’s not a huge window, but if you think of it as a light source it’s probably pretty large and ample. If you live in the Northern hemisphere and it’s a north facing window, you have diffused light all day, every day. Arrange it behind you with your subject facing the window and you’re in business. If your window is set high on the wall, maybe keep your subject standing with a white or silver board somewhere near the underside of their face.
Let’s say your windows are west-facing and you want to shoot in the afternoon. And you’re really terrified of hard light. Keep thinking of your window as a softbox. You just need what they refer to in film production as a “silk”. The same material (ripstop nylon) that is found on the front of most softboxes can be placed in front of your window to turn hard, late day light into a glowing, golden, majestic light bath for your subject’s face.
Maybe you’re fortunate enough to have another problem… Your window is humongous. Good for some stuff, but maybe you want to shape that light a little bit. Black foamcore will do the trick. Arranged on either side of your subject’s face (or both sides) you’ll get some fall-off and keep things from getting too “flat.”
Obviously there are limits to window light. Namely, if you need to shoot at f/16 ISO100… It’s not going to happen. But modern cameras can easily do highers ISOs without hurting image quality. And who shoots portraits at f/16 anyways?
A lot of factors will affect the final outcome of your shot when you’re using window light. Is the room you’re in light or dark? Are there other light sources, like another window? Is the room spartan or cluttered? Rather than think of these things as liabilities, think of them as the things that make your shot unique. Give the same model, same seamless, same Briese to 10 different photographers and you’re likely to get pretty similar portraits. But only you can get the shots created by you, in your room, with your magic window.
