Hi and welcome back.
I happened across triangle lighting for headshots about 4 years ago. I started using it in place of a ring light. Why carry around a ring light and all that comes with it when instead I can use and control 3 lights individually and get nearly the same result.
Shooting with Megan, I decided on using this look to get great, smooth, even light on her face.
The key to this setup is getting your lights set in a triangle and then setting the output to the same power level. I usually use Manual Mode at 1/8 power to give me an exposure of about 1/200 at f/7.1 to 8 depending on skin tone.
The trump card here is the bottom light. Sometimes, depending on the shape of the face, you need to turn the light a bit downward to avoid up shadows or turn the power down a bit so the up shadows are no longer seen.
I use three Rogue Flashbender 2’s with diffusion panels for that soft yet contrasty light.
Here I have 2 Phottix Odins, 1 SB910, all triggered by Phottix Ares.
Here is a proof image. Notice the shape of the catchlights in her eyes:
Three lights in triangular formation, each set to the same power setting, Rogue Flashbender 2 XL Pro’s with diffusion panels.
That’s it for now.
Till next time, happy shooting.
