Camera zoom FX, Camera 360, Camera ICS, ProCapture, MIUI camera.
All of them give, more or less, similar results (you can't expect pro photos from mediocre hardware) and all of them has options that makes them diferent:
- Zoom FX and camera 360 have filters that you can apply right on picture;
- ProCapture has interesting and usable panorama mode;
- Camera ICS has 2x video birtrate recording... etc.
But... what i learned from years of photo hobby and what i missed from stock camera (don't use stock rom long time now) was "touch to focus" option which is visible right on display and really makes changes to exposure of photos. Camera 360 has that one but it doesn't do anything (at least for me) to exposure at all.
So curently i use MIUI camera which have that possibility and it does make photos as close as possible to what i want.
