I have clipped my data frame based on city limits. One ortho has a tranparency and is excluded from the clip, I added a different ortho without trasparency and did not include itin the clip, so the ortho appears more vivid inside city limits. Everything in my layout looks exactly the way I want, but if I export the map or print the map there are additional areas in the vivid ortho that show up outside or the clipped area.
