Hi, I was shooting a gig last night and noticed that some photographs had reflections of the neon signs somewhere else on the frame. Is there any way to avoid this when shooting against a bright object, maybe with a filter or something else?. I didn't expect this from my 1000$ lens. These shots were taken at email@example.com iso 800 with a 40D, no flash, in camera wb set to custom. Thanks for your input in advance.
