Lightroom: Improve adding Face Regions

* Allow copying Face Regions across pictures - Help with duplicate images where for some reason Facial Recognition has missed people or you are manually adding them - People > Copy Face Regions/Paste Face Regions

* Have clicking with the Draw Face Region tool place a square automatically (makes it rescan and guesses at size?) so you don't have to draw it all the time as it's time consuming

I like the second part only.

The problem with simply copying the region from one photo to the next is that the person will likely be in a different spot, and placing a named face region effectively "teaches" Lightroom more about what that person looks like. So, you will be "lying" to Lightroom about their appearance, which will ruin the work you've put into educating it.

The second part, where Lightroom tries again to place the face region automatically is great, though, because if it succeeds, it at least tells you that it can see that there is a face there, even if it can't figure out whose it is. If it fails to find a face, though, it should not just place a box somewhere at random, for the same reason as above.

There would be no need to copy regions unless the faces were in the same spot. Think group pictures where you have a couple of different versions for whatever reason. You can also always remove/move a region if someone's missing/moved, it doesn't have to be perfect immediately. It would save significant time redrawing/retagging though.

Facebook places a box where you click (I think it centers on the mouse) and you can readjust its location if needed. I don't see why I can't have it manually place one where it fails to recognize a face. If they're turned sideways it doesn't always recognize a person, but I still want them tagged.

Really at this point I've abandoned using the feature because it's too clunky and I still need people tagged even if their backs are to the camera (obviously if they're still significantly present), so I can't be bothered to use a feature which (currently) skips so many faces even if they are significantly present.

This is one of the few times I will say so, but I am spoiled by Facebook's version of this feature. It is excellent at grabbing faces, suggesting people, and allowing me to easily add new people with minimal effort. It's also very fast, which Lightroom really can't ever claim to be.

I think you're missing something here. Even if you have a camera on a tripod and the subject is sitting on an apple box, if the subject mere turns her head, that will put the box in the wrong place, and now you'll be telling Lightroom that some chunk of background is what "Ann" looks like. Now in the future, Lightroom will be more likely to guess that a photo is of "Ann" when the background is merely similar.

Bottom line, I think adding that feature would cause more harm than good.

Now, that's not to say that a variant couldn't work. There could be a "Face Detection" box in the "Copy Settings" dialog box, but instead of simply dropping a new face detection region in the exact same spot, it could just be a signal to Lightroom that it should expect to find a face in the photos you Paste Settings onto later. If it doesn't find one, or the face is in a different position, the box will be missing or moved, as appropriate.
