Waterfall photography is a favourite subject for many a nature photographer. In fact, a good waterfall can be a magnet for almost anyone with a camera.
Like any subject in nature photography, waterfall photos also come with their own set of challenges. A beginner can be disappointed with their results time and time again, simply due to simple mistakes that can be easily overcome. Really good waterfall photography is not about expensive equipment or hi-tech methods; just a decent camera and a basic understanding of a few manual settings.
