Faded pencil writing on photos etc.
I did some work with the enhancement of digital pictures many years ago
in school. It is sometimes possible to photograph a text with a digital
camera/scanner then manipulate the result to make faint writing legible.
When you digitize the image make sure the part that you are trying to
read ends up with a medium brightness ie not mostly white or black. The
things to try on a computer with image enhancement software would be
"edge enhancement" and "contrast stretching". The human eye cannot see
small changes in contrast that may exist in the photo and that a
camera/scanned can record. A computer can be used to exagerate contrast
making them visible.
I have not checked the current enhancement software on the market but
this stuff is pretty standard and should be available free or cheap.
There is program called: "gimp" for windows that does this stuff and it
is free. Experimenting with the image i.e. trying different filters and
combinations of filters usually is the way to go.
