Google Photos is not as great as it seems
For someone who only posts images to Google+ (meaning no camera rolls), Google's latest application to manage photos is not really very good. It's certainly better than the neutered product that Google+ Photos had been, especially after they decided that only highlights would be displayed. The new Photos has the same selective memory sometimes choosing to show me only one out 2 to 4 images posted.
And then I discovered their little dirty secret: albums. Both Photos and G+ photos only care about images if you put them in albums. In fact, Photos will go so far as to create albums for you by various limited topics.
This is where the app sucks.
It organizes by two filters, things and places. You can easily remove images from the things categories. It's the places that doesn't work right. I discovered a photo being put under "California" and could not figure out why because it did not have a location. When I was looking at the photo info, I found the reason. My text had quoted The Hollywood Reporter about a film and that is why it got mistakenly put in there.
No setting to fix it seemed to be hiding so I looked for help. Help took me to a Google Forum (they still have those?!) where someone asked for the same setting. There isn't one. No fix. Their question was posted back in September '15. Google had nothing then and they have nothing now.
So, location info or not, Google decides where that photo goes, wrong or right, and you get no say about it. Good luck if they screw up your vacation or wedding or other important event.
