See in black and white
By their nature waterfalls are fairly monochromatic subjects, especially in winter, and with the strong contrast between highlights and shadows they can make great candidates for conversion to black and white. One way to check whether or not a scene has the potential to work in mono is to set your D-SLR’s Picture Control to Black & White, while ensuring that you’re shooting in RAW,orRAW+JPEG mode. That way you’ll see a mono version of the shot when you review it on the camera’s rear screen, but all the colour information will be preserved in the RAW file. If you only shoot in JPEG, the camera will actually process the shot in mono, and the colour will be lost for ever.
