Hi,
I have not been able to understand the graph that shows the noise profile, and in which one can drag the points on the curve up and down.
What are the axes?
Horizontally it runs from black to white, does that mean the brightness levels of the image? (wouldn't make sense, would it?)
Vertically it runs from -100% to +200%, what runs here?
Percent of what?
I need to know if I am to be able to make up or finetune profiles.
Please help,
Sverker

Yes, that is correct.

Of the noise level measured in the main analysis area (the selection used by Auto Profile).
