Do you know Lumina [1]? It has a setting that turns off most post-processing, resulting in very natural-looking pictures. It has more features than I need, and it's free.

Wow, this is a nice camera app. I usually stick with the stock iOS camera but this is a tangible upgrade. Generous to offer it for free.
Ooh, this looks really good. I use OpenCamera on Android but it's pretty limited... I wonder if there's anything like Lumina there.
