In any event the idea for the image above is to have a very small aperture and fast shutter speed with an intense flash (so a new thing I've learned is that I also don't have an adequate flash). The image was taken in full daylight but almost no ambient light makes it to the sensor. Instead it picks up the focused light from the flash, only illuminating the intended subject. Now check out the inspiration here.
