Looks like some banding Fred.
The Canon 20D is supposed to have this problem to at high iso and certain
lenses.
See if you get it with a diffrent lens with the same shot , if you can shot the
subject
again.
Future firmware may help,or as some one said, it may have to go back for a
return.
This is one of the 2 major problems with digital,the other , dust.
Good luck.
