It's been cold and foggy of late. Poor conditions for using a camera. So some people think. Maybe if you are after shots of small birds at distance it is, but fog and mist bring an air of mystery and an unusual quality of light. These conditions can also help simplify images by hiding background clutter and muting the palette.
I prefer it when the mist is being burned away by the rising sun, but even when a fog has settled in for the day all is not lost.
Wildlife photos can be found if you put some thought into looking for them. I spent a good few minutes watching these resting pochard slowly drift, waiting for them to form a satisfying pattern before the fog really closed in.
