One of the most beautiful foxes I've seen is this silver fox. It is a melanistic variation of the red fox, and like all foxes, it is extremely fast. Its movements are actually frenetic. I took this shot during one of my wildlife workshops, and even though this is a captive animal (it is running around an enclosure of a half acre), it is still extremely difficult to capture well. If and when it looks at the camera, it's a fleeting fraction of a second before it turns its attention to something else. Just keeping it in focus requires constant diligence in working the autofocus controls. I use AI servo, of course, and a fast shutter speed is essential to prevent blur. My settings were 1/1000, f/5.6, and 320 ISO. The low angled sunlight was perfect to light up the color in the eyes.
