I think the crux of the issue is that the *viewer* doesn't know that the terrain is tilted; all they can see is that the horizon in the *picture* is tilted. And if there are no other clues, the visual assumption is that it *should* have been level, but isn't. The "Dutch Tilt" works because it is *so* far off from level that the viewer must conclude either that the photographer intended it, or was drunk. :) Andrew On Fri, August 12, 2011 3:50 pm, Don Roberts wrote: > Agreed, if we can resolve the "curved" versus "level" semantic issue. > But I stand by my original claim that the horizon does not need to be > level if the terrain is not.
