For this photo, I used two portraits of my model that I took in section. To start, I took two photos of the same model (one zoomed in closer and at a different angle). In both photos, the background was black and the main light was shone directly in the subject's face, and fill light was not used, so that the only thing illuminated in the shot was the face.

I had to use a large aperture in order to capture enough light for the subject to be seen because it was rather dark. Then, I decided to merge these photos to see what two shots of the same person would look like combined. To me, it looked like the jovial inner-spirit of the subdued model bursting from within him and blazing red with energy.
