No. When you take a new photo in the app, the app is just calling out to the operating system and saying “hey, I need a camera here” and the OS either asks you to choose a camera app or launches one based on what’s available or your prior preference. We don’t have any control over what that camera app looks like or how it behaves. All we know is that it’s going to let you take a picture and when it’s done return a photo file to the iNaturalist app.
We could launch some kind of interstitial screen when we get that file back that let’s you edit, but IMO that would be more annoying than helpful, since it would add an extra step to the observing flow that is generally unnecessary.
We could also build our own camera instead of relying on external ones, but I guarantee that would not be satisfying for the majority of users. To my knowledge, most manufacturer-provided cameras use undocumented APIs or hardware assistance that aren’t available to 3rd party developers like us, so a Google camera on a Google phone or a Samsung camera on a Samsung phone is always going to be better than any other camera app you might install. I guess I should say that’s been my experience, and I assume that’s why, but I have never been able to verify the claim.
