In photographic circles that concentrate on competitions and awarding prizes, judges have gathered unto themselves a group of "rules" or more properly termed conventions. Therefore, to enter competitions, the entrants usually feel constrained to follow certain rules. But these rules tend to stifle creativity. They produce the same old viewpoints, no matter what the subject matter might be.
So here I have presented some rules, each followed by an image that breaks that rule. You decide whether these are "bad" images, or not.
Here the subject is just barely recognizable.
More and more unrecognizable.
Finally, the subject is not recognizable at all.
In the 1st of these 3 images, a woman at the top is peering into her camera-minus-lens to see dirt on the sensor. A man's hand holding a swab is at the bottom.
