Blue Light
So this is a little experimenting with my first speedlight, as low key photography is one of the topics that fascinate me at this stage. It is not excessively complicated to achieve, but I would suggest that anyone attempting this type of photography should first understand the basics of light and white balance settings of your camera.
Or you can completely ignore everything I just said and run with trial and error, it's my favorite way of learning when it comes to photography. The great thing about that way of learning is coming across new perspectives or settings that you never used before, or just a new type of art that you have never thought of before.
