Clone tool nearly invisible on grays

[Nacio Jan Brown]

Is there a way to correct the fact that, against a range of gray backgrounds, the clone tool circle is very nearly invisible? I am cleaning up scores of B/W scans and this is making me blind.

Welcome NJB. As far as I know, you're stuck with that color.

Here's a workaround: Colorize the image first. The quickest way is probably to use the gradient tool, putting the entire image on the high side of the gradient.

Bravo....

With the adjustment brush, there is the "O" key changing the brushed area in sequence: Transparent, Red, Blue or Gray. That would be nice to have that key acting the same with the clone tool! Put a feature request. Link on top of forums...
