Ghost left behind after using Remove

Many have observed here that the replacements made by Generative Remove sometimes don't match the photo's tone. To get better matches, these techniques sometimes help:

1. Adobe recommends applying Denoise before Remove. This can reduce the noise, making it more likely the replacement will match.

2. Try making a larger selection, even including the entire background. 

3. Sometimes there's a distinctly visible boundary where the tone or noise don't match. You can often use the heal tool around the boundary to get better feathering and make it less noticeable -- apply Heal in small brush strokes. Or use a Brush mask with maximum feathering, dropping local Texture, Clarity, and Sharpness to their minimum values. Sometimes, making a very raggedy selection around the object makes the boundary less noticeable.

You need to explain which remove tool you used and with what settings (feathering, opacity).
