There is one part of my image that I need to clone/heal where the healing brush won't work properly. It works fine on other areas, but this one highlight on someone's nose that appears to have little grey areas on it won't heal - it darkens the grey areas. I'm not sure whether it is the healing brush that is the problem or just that area of the image. It is on more than one image and is driving me nuts. I rendered it and opened it in Photoshop, and the healing brush worked fine on it there. Completely flummoxed.
