It sometimes seems like a cheap photo trick to turn an image upside down. Years ago, I did a workshop in Santa Fe, New Mexico, with Jay Maisel. One of his rules or “hacks” we learned was that if you didn’t see anything interesting in front of you, turn around. This mated well with another of his rules: “The U-Turn was a photographer’s most effective tool.” So maybe turning an image upside down can be like turning around or a U-turn.
