A while back photographer Glyn Dewis conceived a process whereas with just a few adjustments in one's camera setting and a speedlight , one could create an invisible black backdrop.
I have been using his process along with a speedlight snoot, on and off, for some time since it produces a moody, low key image, which is my favorite type of photography.
I decided to use this technique in capturing some photos of the Beta fish (es)*️ that have been residing in our house and the results are what you see.
The image below is what the bowl looks like without the magic black backdrop (this was edited (lightened) since I forgot to take a before/after picture).
*️ Orange Beta died overnight due to photographer's negligence.😔😔
If you have never used this technique, you should give it a try. It is a fun way to create a beautiful photograph with studio quality lighting and a subject against a black backdrop.
