well yeah there’s is no dedicated camera album, but you can just search for whatever model of iphone you have and it will pop out a list of every photo taken with that model of phone

sharing files has never been an issue for me. if you got a macbook just use airdrop to send it directly. if you have a windows computer then you g-drive/onedrive/dropbox/etc. then you’ll probably have to save the image file to Photos cos most social media apps wont accept uploads directly from the Files app
