Photoshop: Edits using the Patch Tool are too dark
I'm having a problem replacing part of a background on an image using the patch tool. I select my area, drag to my new area (looks great the way it is) and when I release, it turns dark. My opacity is at 100%, I have looked for a random setting that would be blending or something rather than replacing, but I can't find why it won't just move over the background that I want as it looks rather than making it darker. Help?
