On the subject of flipping, if I take a picture with some human action across the frame, it generally looks correct with more space on the right. As I live in the Western Hemisphere, I take it this is influenced by the fact that I read text left to right? If I was from an Eastern Country where text is read right to left, would such a picture seem to have a better composition when flipped?
(Blanksy - note flipped not flopped)
But in Arabic for instance the text goes right-to-left while the numbers go left-to-right. If you are scanning the negative digitally, this could have serious consequences unless you have palindromic processors.
Actually instead of flopping the negative, try turning the enlarger inside out. That way the image goes in the other direction but without all the other problems.
Wait a minute. When I shoot large format, the image is inverted on the ground glass. If I flop the negative, it will print the way I saw the image when composing the shot. If I want to keep the universe in order, shouldn't I flop all negatives?
Either flipping or flopping or reversing or mirror imaging or...whatever, turns into a quibble over semantics when everyone already knows darned well what you mean.
