Water is one of the crucial ingredients of all living creatures. While it gives live, it can also be an intimidating force of nature.
Waterfalls are part of many natural landscapes, yet I feel they are different. While a landscape is often calm and motionless, waterfalls are always moving and ever-changing.
Each waterfall has its own character and needs to be depicted that way. Some waterfalls are strong and fierce and a long exposure would undermine that. Other waterfalls are calmer and smoother, where a short exposure to freeze the movement would contradict their flow.
