Hello - I have Lightroom 5. I have imported a color photo. I am trying to use the Adjustment Brush to change the background to Black and White and leave a portion of the photo in color. When I begin painting the photo with the Saturation at -100 I don't see any changes to the photo. I push the "O" key and still nothing. I have tried to reset the photo, restarted Lightroom and still nothing. Please help.
Set Flow and Density of the brush to 100
Reduce it where you want the effect to blend.
I will try that. Thank you.
That didn't work. But thank you for trying to help.
