I am looking to get the best pdfs for sheet music possible.
Looking for best way to go about scanning so that the copy can have a darker print than a light original, to clean up the background so it is “whiter”, remove blemishes, etc.
For sheets already in the pdf format am interested in the same as above along with being able to straighten a crooked image.
Also any other editing that would be beneficial such as typing in chords, blocking out incorrect chords and the like.
I've been using a 15 year old version of Paperport
Paperport (scanning software) It contains all the tools you need for scanning music into PDF's. I've scanned about 1500 songs already and touched them up as needed.
You can change the DPI setting to make the notes darker...or lighter to avoid what's on the other side of the page.
auto-Straighten a "crooked" image
erase what you don't want
add what you DO want
enlarge and shrink images
convert one image type to another
etc etc etc
I'm sure a more recent version does even more, but I've been a dedicated user of the original Paperport for many years now!
