We're doing a photoshoot of a guitar collection. The photos are coming out great, but there is a specific color aberration on the strings. The guitar strings are braided by a thin metal wire, which probably causes reflections and interference of the reflected light. (Please see the picture)
We've tried to get rid of the color errors but without any luck. Now we are quite desperate so any help would be greatly appreciated.
We're shooting on a Hasselblad H3Dii with a Hasselblad 80mm lens.
