The program does exactly what it says, crop face area out of image without affecting other areas in picture or distorting the rest of picture. I can't find anything to dislike about this application so far. It works great with my Canon A520 camera when using a tripod and macro setting. Sometimes there are some small parts left over after cropping which requires me to do manual editing but nothing big enough to be considered an issue. This app has been very helpful while creating IDs for people who have no photo available.
