Help Can camera app software alone improve photo quality?

I'll keep this one short - I just want to know if anyone has tried some of the available camera apps, and actually noticed better Incredible photos with less noise, brighter indoor photos without flash, color rendering, or better focus. If you could explain any theoreticals on how software interacts with the hardware to produce such improvements, that would be appreciated too.

The issue is that it still has to go through the camera driver loaded into Sense. HTC has acquired the SDK to develop a more advanced driver, it just depends on when we might (if ever) get it. Right now we're running a very generic driver.
