Hi Franz,

there is a fundamental difference between B&C for grayscale and RGB:

Grayscale: B&C modifies the way how the image is displayed, the image  
data remain untouched.

RGB: B&C modifies the image data. This means:
- Any operation done after B&C uses the modified (adjusted) image.
- If you change the image data (in a live view), the new image won't  
know anything about the B&C adjustment done on the previous image.
