I've found that when using the brush for local adjustments like exposure, it can leave ugly dark traces. Has anyone else encountered this?

 

Thanks

Have you tried altering the feather setting?

And do also check AUTO MASKING. That helps to contain your adjustment.

Thanks for the comments Mark and David. I don't think it's related to feathering.

 

I'm posting a typical example, first the whole picture

Now a detail, woman in hat exposure in face lifted 0.7 stop, with dark deposits visible

 

 

Now detail without exposure lifted, darker but no deposits

I think your lifting of exposure locally has started to show the effects of digital noise, This is always a risk when trying to reveal more detail in shadows. Either treat with an adjustment in LR Luminance reduction, or decrease the effect of exposure increase in your local adjustment.

Empty splotches within the stroke suggests that automasking is selected where the settings don't suit what you want to do there. It depends on your content what works best of course. I find it invaluable. I suggest that you experiment with all of the brush options . You may find it helpful view at 1:1 and be sure to use Show Selected Mask Overlay

This is fairly typical for lifting the shadows in an image that is already on the underexposed side, especially at higher ISO. It is a rather lumpy noise effect. The only thing you can attempt to do is to apply a bit of blur locally.

I suspected as much. I've been in a habit of lifting exposure in faces but recently been reining that back, not least because whilst one might get away with it in a web post, on a print it could look rather ugly.

 

Thanks

Try setting 'flow' on the adjustment brush lower. This means it works like an airbrush and you need to go over an area multiple times to see an effect. It allows more control and might mean you stop before getting the noise.

As jaapv noted it is ISO noise.  I would use the adjustment brush noise slider to reduce it.
