I have a photo of a puppy, where just the top of the head where the hair is, is cut off - out of the camera shot. When using the quick selection tool and placing this image on a new background, the top therefore has a flat line at top. Which is the best feature to try to replace what was cut off in that original photo (shown below) ? Would that be the content aware patch tool? Or would you just use the paintbrush to try to paint it in? With all the subtle colors, that is difficult.
Please give me instruction with the suggested tool. I'm a beginner.
