Anyone else do Photo Restoration?

Just a little for personal use. This is one I did of my 3rd great-grandmother from a rather dark tintype. Some of the things I did was to photograph the tintype with cross polarizing filter to get rid of excess glare and on paper surfaces to help remove texture. The before shot was done without filtration. A lot more detail showed up with the filtration. Also I used some bandpass filtration using the highpass filter. What you do is use the highpass then gaussian blur to isolate spacial areas of the image. I used one setting to bring out the lace collar, another for the hair texture, one to increase the facial modeling, and one for bringing out the folds in the dress. The background was pretty messed up with dust and other crap, so I just recreated a new one.
