One good news at least … when I get home I’ll check out the pictures in Lightroom on the PC.The camera apps own RAW is applying some processing, but i think that is after taking a photo, and viewing the picture in Apple Photos. If you edit the photo, or open it in Lightroom for example, the photo gets "cleared" from Apples processing.
Regarding camera apps with more control and less processing, there are many alternatives; Halide, Moment, Proshot, Reeflex, Lightroom among others.
Well that’s the one thing I don’t like about iPhones: The chains from Apple, Apple says you cannot dismiss the lock screen by just using Face ID, then you have to swipe up! Millions of customers complain about it? F*ck them.
You can only download Apps from the AppStore.
No, if we want your photos to be processed then they get processed, nothing you little worm can do about it. lol
Etc ..
About these things I’m jealous for Android users.
On the other hand there are many things that are better on iPhone / iOS…
