Lightroom: Zoom in on faces

I want to be specific about this to the LR team. Pro cameras can ID the shape of a face in the photo. The cameras must be tagging these face locations in the meta. It would be pretty simple for LR to pick up this info and calculate the "center of mass" of the faces so that LR could intelligently zoom in on a photo when going 1:1. I am NOT advocating unique face detection which is a totally more complex endeavor.

After processing over 100k images a year through this software, hitting the mouse every time I zoom is contributing to a significant chunk of dev time. Make it so. Engage.

Step one: make all the cameras agree where to put this information, and how to encode it.

Adobe has to be careful about what proprietary metadata to attempt to extract, because doing so is a thankless job. Sorting out lens info and GPS data is hard enough, and that still fails to work sometimes because of the way the metadata is stored.

Even stuff that is supposed to be "standard" (there really isn't a real metadata standard because EXIF is ad hoc only) like various timestamps is stupid hard for the manufacturers to get right.

Until the manufacturers are told there is no economic advantage to obfuscating metadata, support vendors have to be choosy about what features to support.

A plugin that uses EXIFTool to attempt to extract this information for some purpose might be possible.

This is not a bad idea, don't get me wrong. But it is important to have this discussion in the correct context. Much of this is outside of Adobe's purview.

If Adobe wants to ignore metadata coming from cameras (my Nikon D750 DOES identify faces - not who but it does put a box around a face), Adobe could run through the set and use its own algorithms to find faces WHICH IT DOES ALREADY. Then, allow me to press space bar and zoom in on the first face. Hit a key to jump to next face. On my D750, I rotate the camera dial to jump between faces so I can find people blinking in under a few seconds.
