I have asked myself. "Rules of composition" don't answer it. Gear and setting don't answer it either. My Blog post attempted to answer it. Let's discuss this in the comments of this post.

With my Nikon D5500 I didn't consider EC was useful when discussions went to use EC. Very recently I discovered that I can use EC, Exposure Compensation., with my OM-D E-M5 iii. Menu->Button Functions->+/--> select Exposure +/- (usually the default). Next scroll down to Dial Function->scroll down to M/B select front dial to +/-. Now when auto-ISO it will adjust the ISO within the Auto ISO settings. Other camera Olympus/OM System bodies may have different Menus. Other manufactures mirrorless bodies may have similar functionality.

Those who are using Lightroom and want to watch a video that discussing sync by Terry White I think it is helpful. I use LrC and use sync so I can see, edit on any device.

Someone asks: “What settings did you use?” BUT… what do you really need to know to understand why those settings were used? Use the comments to answer; Can you reproduce the photograph? Why or why not?

How does Goodhart's Law apply to photo evaluation? There’s a well-known concept in economics and management called "Goodhart’s Law": "When a measure becomes a target, it ceases to be a good measure." When a metrics are the main goal, people start optimizing for the number/rule instead of the actual goal—and the overall quality suffers. Think about how we evaluate photographs.
