White patches

Many times when photographing an animal or bird in a tree, the sky seen through the leaves is very light or white and it detracts from the subject.  Our eyes are usually drawn to the lightest part of a picture first, and our attention returns to those white areas again and again.  The ideal is for our eyes to focus on the subject and not be distracted this way.  Sometimes I use the clone tool to fill in the offending white areas, and other times I will replace the background entirely.  In this shot of a red panda from China, I wouldn't attempt either simply because of the fine hair around the periphery of the animal.  No software would be able to handle this subject such that a new background would look entirely natural. If I had photographed the panda against a white sky, Topaz Remask 4 would do a good job of separating it.  But the reddish hair against the greenery would be impossible to work with.  So, in this case, I just had to accept the image as it is.
