The standard iOS "take a photo" view has its "navigation and action" bar at the bottom, unlike (almost) every other iOS view that has the navigation/action bar on top.
I assume Apple broke consistency in this case for reasons including:
- photo taking is often an "immersive experience" (like gaming) where breaking the normal rules is OK
- a photo-taking view needs three buttons (cancel, save/use, and "take picture") and the usual navigation bar only allows two buttons, so the user can get more real estate for the photo by only using one line of toolbar.
But the effect can be jarring in apps not focused on picture taking, like Amazon.com's app where users only take pictures of products as part of searching for products.
Can you think of any way to make photo views seem less "alien" to an app like Amazon's where picture taking is just one of many tasks that the app supports?
Here's an example of a "Normal" view:
