I often need to post process my photos to level the image.  Whenever the image is slightly tilted, it take a little extra time to fix things afterwards using software.  Wouldn’t it be nice if a digital camera could automatically adjust images for a perfectly level horizon?  I believe there are some patents already out there for micro gyroscopic sensors that can detect the tilt of the camera and automatically compensate for camera tilt in the image.  This way, you can hold the camera at any angle and always get a perfectly level shot!  I hope somebody can come out with this feature soon.
