In this video Glyn Dewis demonstrates how he gets his ‘Invisible Black Background’ effect when taking a portraits which will allow you to take a low key atmospheric portrait with a black background anywhere – even outdoors as he does in this video.

To get the shot Glyn just uses his DSLR, a single Speedlight Flash, a cheap umbrella and a PocketWizard to trigger the flash (although you can do this with any method of triggering a remote flash that you have).

Want to see some more examples of what can be done with this effect – check out Glyn’s blog posts on the topic here and here.
