Example: Blurring a face in a picture without distorting the entire image
There are many ThumbsPlus Filters that can be tried, but the most commonly used filter to disguise a face is the "Mosiac" filter.
I have attached 3 images that illustrate the "Elliptical" Selection mode, (so you can select the face with a circle), as well as suggestions for ThumbsPlus Filters for this task.
