I don't use nebulosity however the principles are the same.

Study and learn the following:

1:The difference between 'Linear and Non Linear'.
2: What a histogram is telling you
3: What 'stretching an image' does. Also called 'developing', or 'histogram transformation'.
3: What 'curves transformation' does.
4: Play with 'saturation' and 'hue' controls.

And finally, if you over expose an image, no colour at all

Question 2 is a hard one and in the nearby thread.

Have fun!
