I have a professional photoshopper where I work. I can question him tomorrow and report.
It seems like a lot of trouble to change the folds. But, nerds ARE known to do strange things. They get tingles, ya know?
That would be great. Just seems to me to be a whole lot more unlikely that very prevalent 3-D folds can be so completely removed from an image...as apposed to 2-D words or images on a page.
I can tell you right now folds and really any sort of blemish are easily removed.
Or you can add marks & aging, whatever.
Basically if you have the skill and patience you can do just about whatever you want.
I’ve often had to scan documents and I’ve cleaned things up from something as simple as removing staple marks- even over text- to removing lines creases wrinkles folds tears you name it. Anybody who pushes pixels for a living will attest to that. Some of us have advanced software that can bring out details previously unseen.
