It's upside down? After 30 years, I really don't pay much attention to the orientation. And since I make single transfer carbon prints, the images end up I don't mind looking at the image reversed on the GG. Not to mention that I learned photography using a TLR Rolleiflex. Backwards is normal enough to me.

Once years ago I remember spending a lot of time under the darkcloth and when I popped my hear out from under it, it was the rest of the world that seemed upside down.
