Online follow up on my restoration thoughts

Well well it’s all up there you just have to search … I followed up my thoughts on restoring old photos by carrying out some online research … surprise surprise I found just what I was looking for. Don’t you just hate it when someone takes your thoughts & puts them into words you had in mind but just couldn’t get streamed logically!!! :-) No really this guy puts my question out there … mind you he has had several more years of experience than I!

To restore an image or not?
