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.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
