[Revolting cat!]

Your best hope may be that the photographer when we identify him has other shots in the series and that the hand in the karate shot is not as overexposed on the original film as it appears in print.

Even if shot was over-exposed, and assuming it was film, a new print of it could be dodged (selectively exposed) to tone down the burned-out area, and the photo then enchanced. Again, what if it is her ring? Can't see what how that would link him to the murder. No proof Chandra was wearing it when she died. Likely she was, so it only adds to circumstantial evidence.
