This is overexposed but I still liked it because of the reflection. This mallard drake dashed into the water when the fox appeared - he didn't want to become the fox's dinner!
I think when the sun keeps coming out and going in again, I shall have to put my ISO on auto as it is not easy changing settings when you are taking wildlife photographs as you only have a moment to get your shot. It's a challenge but that's probably one of the reasons I like wildlife photography as you really do have to shoot things so quickly with not a lot of time to think! Or more importantly act by changing your settings!
