Negative control points, found in parts of the collection such as Color Efex, are missing from Silver Efex. A consistent user interface would be welcome.
Hi Pierre. I agree that the various UIs in the Nik tools should be standardized. Until then just remember that a negative CP is nothing more than a CP that makes no adjustment. Again because of the differences in the UIs this is accomplished in different ways. Some have opacity sliders so just reduce opacity to 0%. Others have no opacity slider so just place the CP and make no adjustment, but it would be very nice if these UIs were uniform.
