The photograph accompanying this question is a section of a photo taken with a Canon 5D with a 24-105 mm zoom lens. As you can see there is a strong moiré effect on the material of the jacket. Other photographs taken indoors and outdoors of the same jacket some have a moiré some do not. Is there anything to do to avoid or eliminate the moiré? Would a film camera have given better results? Any suggestions or explanations would be appreciated.
