Any idea what caused the black rim? Happened on quite a few.

Cheers.

It's a shadow.

Was there an on camera flash firing the OCF?

Hmmm, doesn't a shadow have to fall on something?

Cheers.

I'd figured that.....Question is ....How to avoid it when using OCF? Is it simply a case of moving the flash slightly further away or changing the angle slightly?

Yes, obviously… but what caused it?

Could you say more on your setup, Andy?

So what is behind the subject?

Nothing at all .....there were some rocks to (as you look at the photo) his left side...probably about 8 -10 inches away ....but I think the black line went all round his head.....

Usually issues with unwanted shadows on backgrounds are caused by the subject being too close the the BG, it's one of the common starter errors. I wouldn't move a light to change a shadow on a BG the light position is dictated by what the subject should look like.

Long shutter speed?

Is the BG a sunset?

Long shutter speed, subject movement, the black 'shadow' is the silhouette of the unlit subject.

Easy with all the info.

Just looked at the exif Phil and shutter speed 1/13th.

Sunset in the BG, yes.

Cheers.

The answer is a higher SS and higher ISO.

Not a long shutter speed but yeah.....bg is the dyimg embers of a sunset

Would the light from the flash have bounced off the rocks causing it ?

Depending on the meet, I might be happy to bring along some toys to help.

[tonguefirmlyincheek]The other solution (favoured by brain surgeons) is to completely immobilise the head by screwing it to a frame bolted down firmly. Probably easier to use Phil's suggestion![/tonguefirmlyincheek]

(I have the scars to prove it!)

Was the camera on a tripod? It looks a bit like a drooped camera before the flash fired.
