I'd just load up on camera apps, honestly. In fact I have done.
No one thing is probably going to scratch all your itches.

- Photo Marker
- PhotoBeamer
- Photo
- Photosynth
- ProShot
- Rawer
- RedLaser
- Remote Viewfinder
- Sketch Camera
- Slowly
- Sophie Lens HD

OK. Admittedly that is a lot. I didn't realize quite how many I had collected until I listed them out. Some are no longer published. Some are redundant. Some only get dusted off once in awhile. But you get the idea. It sounds like no one thing is going to do everything you want. Certainly no one camera app does everything possible. Try some out and find out what they are best used for and use them for that.
