I think you mis-understand how iOS privacy controls work. An app doesn't get to 'see all your photos' just because you grant photo access, you still have to select which photos to put in the app. Same goes for camera, that just let's the app pull up the camera interface, not be able to access it 24/7 for whatever purpose they want. Same with the mic.

The apps do get permission to see all photos. How else would facebook or google photos automatically upload all your photos. Both apps have the option to do this. It requires no extra permissions on your photos and you don't have to select anything. It just requires giving permission once to "photos"

I don't think this is correct. The Facebook app regularly shows me all the photos I have taken today and asks if I want to post any of them.

The Facebook mobile website can't do any of this, is just as functional, and easier on your battery life. I highly recommend it!

I can't tell you how many times I've definitely had a photo show up in the "do you want to post this" preview that I most certainly would never want to post.

I feel like I'm having a heart attack every time thinking I posted it already. That feature sucks.

Honestly that sounds really creepy.

Of the 6 apps under discussion by greggman, 4 are Facebook properties. Facebook is creepy.

Whenever an app asks for access to Photos to save an image or to read a photo, it gets access to the entire camera roll (all photos). So it can certainly upload your entire photo library someplace if it wants to, subject to foreground usage time, network speed and background activity (limited by iOS).

Compared to that workflow, if you open the stock/official photos app and use the share sheet to share one or more photos with a specific app, then it would get only the selected photo(s).
