Last 4 sliders of Adjustment Brush not Working.

Rastis77  wrote I set Clarity to minus 100 and it worked. Clarity and sharpness however are different tools with different effects.

Positive values of Sharpness are indeed very different in nature, to positive values of Clarity.

But negative values of the two are much more comparable IMO; or better, can be used in combination toward similar ends.

AFAICT Clarity presents two visually quite different sorts of adjustment, as two ranges on the same slider.

Sorry but I have to ask.

Have you actually used the Brush to Brush parts of the image you are working on?

None of the adjustment sliders do anything until you brush part or parts of the image.

You can brush first then move the sliders or move the sliders to what you think you want and then brush.

I had to zoom in to 2:1, basically 200%, and move the sliders back and forth from one extreme to the other to see the effects.

Try an image with a close up of a face. Zoom into an eye and use the brush tool and adjust the Sharpening slider to +100 then brush over the eye. Then move the other sliders right and left to see if you see there effects.

How visible the effect will be, does depend on how full of contrasty edges / texture / noise that part of the picture is.

I don't know what that message means either. You have to consider that that message is three years old. I don't remember a basic extender. Some of the adjustments in the adjustment brush are very subtle. To see the effects it's sometimes necessary to have your image zoomed to a higher magnification.

If you have applied a lot of global sharpening (in the Detail panel) then the Sharpness slider in the local adjustments can make a large visible difference as you slide it from -100 to +100. That's because local adjustments adjust what picture data is input to the global sharpening, which then exaggerates that.

If you have little or no global sharpening set, there is correspondingly less visible result from the local tool since edge contrast is not being "multiplied up" by that.

Noise: this is quite similar in that if you have applied a lot of noise reduction, there is a lot of visible difference made, from applying more or less NR with the local tool. If you have applied no global NR or only a little, then the local slider's visual action is left quite subtle.

Moire is a targeted tool which probably won't make much visible difference to an image, except specifically where it has got false colour artefacts (or, I suppose, genuine colour detail which happens to have that same appearance so far as LR can detect).

Defringe: similar situation as with Moire, AFAICT.
