I deserved that, sort of. Apologies for the in-the-moment screed, which I usually make a point to avoid.
That said, going to my phone’s Settings/Search takes me to a list of apps, “Photos” among them. Clicking on this, I have only two on/off choices: Show App in Search, and Show Content in Search. I see nothing like “Show related content.”
In any particular photo, when I want to add a caption and tap “Info” to do this, the glowing line appears. I may have something like “Look Up Landmark” appear, or I may have nothing at all, such as when I had an image of an Archaeopteryx. All I see is a glowing line. Wouldn’t an Archaeopteryx be something my phone might suggest more information on?
At the risk of going too deep into the weeds . . .
The first time I saw the silhouette line introduced, it showed up—and showed up only—when one held one’s finger on a figure—a photo of a friend or family member, for instance, that one might want to place on some other background. A nifty little feature. The silhouetting that shows up every time you open Info is a distraction. Especially when no additional information is suggested about the subject, anyway. One doesn’t know why it’s there. And even when there’s more information available—about a landmark, or a bird—the line is usually unnecessary: when a bird or a building is obviously the subject of the image, why outline it? Are there images where the subject isn’t obvious? I don’t know. Maybe. Then I might just touch the Thing I Want To Know About, and silhouetting could confirm it, and that would make sense.
Anyway, apologies again for the tone. The question remains. How do I turn it off?
