If this a question you have asked yourself even once, then here in this post is the answer.
The answer is to get the flash off your camera somehow. To know specifically how to do with your flash, read the manual.You can use it wireless or wired. Once you get it off your camera, use that little foot that came with your flash to sit you flash anywhere. Also, if you noticed, the bottom is threaded so you can mount it on a tripod or lightstand. This is really useful when you want dramatic, directional lighting.
