Using the better version, I tried to make the face of the Babushka Lady more recognizable. Unfortunately not with the desired success. With the software GIMP and OpenOffice I tried out various brightness and contrast values and applied sharpness filters. However, I have to be ashamed of the result:

Unfortunately, a clear face cannot be seen here either, and if so, it looks more cartoon-like and not like a real person. I'm pretty inexperienced when it comes to image editing. Certainly someone can do it much better.
Best wishes
