select area for clone stamp source
I want to replace the black background in the 6-digit tag below with black from another tag which is not crushing the shadows (see 2d screenshot). Using the clone stamp tool, how can I copy black only from the tag in the 2d screenshot to paint over the black in the tag in the 1st screenshot? For the target layer, I have a layer which is the entire tag (background plus numbers) and a layer above it which is the numbers only. So I can paint on the lower layer without affecting the numbers. But I'm not sure how to select the black only in the source. Thanks.
