Today I have uploaded two photos taken in complete darkness using a flashlight to light up the object. In one case a water tap, in the other my own eye. This is a technique I experimented with a lot, and especially the eye turned out real cool, in my opinion.
In the case with the tap the location was much bigger and the object larger than the eye. A stronger flashlight was used, and you'd be amazed at what kind of cool pictures you can actually take in complete darkness using a number of flashlights and people to shine them on the object from different directions. I recommend you try it!
