I'm not a technically good photographer so I try to get something in the pic that makes it more than just an image. Still water is good for imparting a feeling of peace and quietness and for reflecting subjects,,, in the opposite way a stormy sea illustrates the fury and noise,,, dissipating and enhancing reflections and light in a way that editing cannot do.
Excuse me putting an image on your thread,,,,,,,
This is a canal-side snap,,,, I have several similar taken at the same time but they lack the foot! leaving the image without a feeling of scale. So the boot remains and (to me) the eye examines the leaves first and then the trees in the reflection and the floating leaves all helped by the strong diagonal line. It's just a quick snap taken with a compact but reminds me of an Autumn stroll on a quiet afternoon,,,,,,, and that justifies the image a place alongside my favourite images
