Could you please share the version of Lightroom that you are using ?
and the screenshot of your Adjustment Brush panel ?
With the Erase brush selected, did you paint over the areas from where you wanted to remove the effect of graduated filter to remove it?
Here is mine (Reset button is at the bottom) :
I use version 6.2.1. I could not paint with the Erase Brush because I could not select it. "Erase" appears brighter on your screen shot because it is selected. It doesn't work on mine (It does work using Brush "A" or " B", but then I don't erase of course, following the Graduated Filter tool). The Adjustment Brush tool box looks the same as your on my computer. On Lynda, the toolbox also includes a "Reset Brushes" button to the left of the "Reset" button. I don't know if that anything to do with not being able to select "Erase" but it is not working.
Reset Brushes is not there on my end as well.
About the erase brush not working, I would suggest you to restore Lightroom Preferences once.
Follow this article to do that : https://helpx.adobe.com/lightroom/kb/recover-catalog-images-resetting-lightrooms.html#id_9 0046
Nope that is not the one.
Follow the below instructions :
1. Quit Lightroom and open finder
2. Click on Go menu (at the top) and choose Go to Folder
3. Type ~/library and hit Go.
4. Open Preferences folder
5. Rename com.adobe.Lightroom6.plist to com.adobe.Lightroom6-old.plist
6. Relaunch Lightroom
Did as you suggested but it makes no difference. The "Erase" brush does not work.
Create a new catalog by going to File> New Catalog> Import a few images > test if you are able to access erase under Adjustment brush
tried that and it did not work. I'll try again
New catalogue. New photo. It does not work. I used the Graduated Filter first and then tried to erase. I can't pick " Erase".
Just found the cause here..
The steps that you were following so far :
1. Apply graduated filter on the image.
2. Select Adjustment brush and choose erase
This erase cannot be selected because there is no pin of the brush to be erased.
For the adjustments to be erased, there should be a pin.
The correct workflow would be :
1. Apply the graduated filter on the image (do not click on done)
2. Select Brush option within the graduated filter (this is available under mask: next to edit)
3. Choose erase from there
Here is the screenshot for the same
I am using 2015cc 1.1
Note that at the top of the brush window the word BRUSH has been added to right of EDIT. Click on the BRUSH and you will see the erase selection at the bottom of brush panel. I have worded this poorly but can tell from pics.
When you are done editing the brush, click EDIT at the top of the panel.
Thank you so much! That worked. You are my hero of the day. I'm still curious about the "Reset Brushes", also shown above. It may not exist in Lightroom 6.
glad to know I was able to sort this out for you.
And yes, reset brushes is not there in Lightroom 6.
This was the first time I’ve used an on-line forum for anything, and useful it was! Thanks
