Weird distortion ?

Muineach

I'm finally going through my collection from the summer and I came across this one (straight from RAW), there's seems to be a distortion around the head, where it goes from normal colour to darker and it seems to "ripple".
It was taken at ISO 200, f5.6, 1/1600.

Any ideas what might have caused it ? just curious
Thanks,
Muineach

Maybe it's due to an object being between the lens and the subject, but the object is too close to focus on? Something like taking a photo through a wire fence, where the focus is distant on a subject, but you can see distortion due to the fact there is something there.

Without seeing a larger version, it's hard to guess.

Looks like moiré although unusual to see it on grass like that.

Yeah its almost certainly something between the lens and the subject. The ripply effect is probably down to the lens' rendering of OOF elements in the picture. Some lenses have a sort of 'double image' on OOF elements.

It could be as simple as a blade of grass, and the ripple is cause by it moving when the shot is being taken.

i know this is stupid but it looks like you caught the fox screaming .. and the weird curve is the sound

Could be speck of dust on your mirror? Did you change lenses while you were out an about?

Yea I can see where your coming from with the grass, it's a strange effect when it's nearly matching the fox's head but, when I look at the fox's nose there appears to be two shadows from grass, so I reckon your right.

I've seen this effect before at the zoo with fences but I never saw it so "ripply" :rolleyes:
Thanks all.

hehe , he wasn't screaming he was eating a leg of a chicken (leftovers)

Pretty straightforward explaination on this one... the fox is moving so fast you caught him breaking the sound barrier, just like a jet!
