If you have this problem it is very apparent when doing this.
Hi David Picked up on this thread a bit late, but yes I have already seen the same problem. I noticed it on some shots of people wearing dark grey clothes & the bottom half would have a magenta band. I replicat3ed the effect by shooting a greycard & didn't have to increase the saturation to see the problem. Haven't had time to contact Canon yet due to a busy schedule & the person I know best at CPS is now at Wimbledon. But will do soon. Do get in touch if you want to discuss this more (we met about 3 years ago, when you were selling a scanner).
