technique - Is this photo showing lenses apparently hanging in the air a Photoshopped composite, or was some other trick used?

Is this image showing a photographer surrounded by apparently-floating camera gear Photoshopped, or was a special technique used?

Answer

I'm the photographer, who made the picture, and I used Photoshop to make the strings invisible holding the lenses.

This is not a composite. The picture was made from 1 shot. The CE logo on the lens confuses people, because it looks like it's upside down, but actually it's reflected from a mirror.
