On the other hand

Art directors and designers sometimes flop an image to make a more pleasing layout. Most times, if it’s a landscape or still-life, there’s no problem. Sometimes, like if there’s distant signage that looks all Cyrillic or some guy in a stock photo has his pocket square on the wrong side, it’s slightly jarring. But what do I care. But look here – you can’t do that to musicians if the instrument is in the picture. It’s just wrong. Unless you’re designing materials for a Jimi Hendrix tribute where you might be specifically asked to do so. Then it would be okay.
