2. What does this mean? It means you need a tripod
To some of you this next tip may seem incredibly obvious, but it needs to be stated loudly: invest in a quality tripod. This is really what will set you apart from simply, playing around to actually trying to capture compelling images. You need a solid, sturdy, mobile platform to place your camera. You need the best tripod for night photography that you can get.
Many people initially try and get away with simply placing their camera on a solid surface. However this misses so many compositional opportunities, and dramatically increases the chances of having a blurry image from camera shake.
