What the heck does a Circular Polarizer/Linear Filter even do? Let me show you!
What you'll need:
How to use it:
Firstly, after you've posed your models and composed your shot, you may expose your shot for the background. (this means you set your shutter speed, aperture and ISO accordingly so that the background is lit the way you want it, regardless of how under-exposed your models will be.)
When you have your desired exposure set, the second step is to bring in the light as close as you can without ruining the composition.
Third step is to then adjust your power settings until the models are perfectly exposed along with the background. It may take a few test fires to find the perfect balance.
