I used to have camera which can adjust the exposure for outdoor photos. So I tried to write an addon to manually add exposure functions.

The interesting fact is the mozCamera exposure API part of MDN doc is incorrect . By exploring with WebIDE, I found:

1. Can use `window.app.camera` to access.capabilities.min/max/step of ExposureCompensation;

2. getter of exposureCompensation is not available in camera instance, so I can't get current exposure compensation
https://developer.mozilla.org/en-US/docs/Web/API/CameraControl/exposureCompensation

3. setter of exposureCompensation is not available in camera instance, so I can't set exposure compensation

[Mike Habicher [:mikeh] (high bugzilla latency)]

The MDN documentation is out of date as of bug 1020497 (June 2014).

The correct usage is to just read/write the .exposureCompensation attribute of CameraControl, subject to the constraints of CameraCapabilities.min/maxExposureCompensation.
