I have to disagree with the shadow theory and the camera shake theory. I don't know of many cameras that put their flashes under the lens. If the flash were over and left or right then the shadows would show under the subject and not above it. The shadow would also be only on one side or the other and not surrounding/haloing the subject. After looking at the meta data you used 1/125 sec, f/5.6, ISO 320 which is capable of registering ambient light as well as the flash. Also your shutter speed is still slow enough to capture subject movement. While 1/125 usually freezes motion from a sitting subject it is possible for a subject to give a quick movement and haze the shot and that is my theory. The curtains show no signs of movement, only the subject.

Try using 1/250 second (usual flash synch speed these days) for flash photography and close down the aperture to f8. While your at it, if you're that close for the flash shots then choose ISO 100.

Brilliant deduction Sherlock. I would have to agree with you big-guy.

Took this photo at a dinner where the guitarist was performing. Used my Sony a77ii with a Tamron 16-300 lens, and a Sony f43 flash for fill. Didn't notice the "shadow" when I glanced at it on the camera, but later it certainly got my attention. Don't think I've seen this before and wonder what happened. Actually kind of like it, but was entirely unintended.

We've seen this before. It's something to do with the flash, shutter speed, and movement of the subject.

Can you post a photo of your camera & lens with the flash mounted as it was configured when you made this photo?

TIA

I don't know the correction needed, but here is the camera data. David

All you wanted to know about ghosting, but didn't know you should ask.

Looks simple to me... he moved while your shutter was open.

Looks as though it is a shadow from your subject on the curtains directly behind your subject. You should have bounced the flash instead of shooting it straight on...

Go with birdpix. Ghosting it is. The shutter speed needs to be bumped up, or aperture tightened. You are getting too much light for the flash in that situation, thus the movement of the musician caused double exposure.

I think you flinched when you took the picture. The whole camera moved downward when you pushed the button.

But it's not camera shake. It's subject movement.

Look at the curtains and the microphone. Static.
But the singer with his guitar is ghosting.

If it were camera shake, then the entire frame would be affected.

Long ambient exposure + flash freezing the action = the result you see in the image.

(Long in this context is relatively speaking.)

And as birdpix mentioned, some photographers do that deliberately with great results. Especially in dim environments with lights in the distant background and a close subject.

I thought it was what I'd call camera flinch, like a shooter flinches when pulling the trigger. But I think you're right. The player must have moved quickly.

Yep--agree about ghosting, and will experiment. Thanks again
for the insights.

Birdpix is right! If it were a shadow it would follow the contour of the drapery.
