using LR to enhance old documents
I have a project where I am importing images of old documents into LR. These are mostly copies of handwritten, centuries old documents that I scanned and are now on my computer. They are mostly black and white though a few are color. I would like to use LR to crop and possibly enhance them - play with contrast, sharpening, clean them up. Is that possible and if so where would I best learn the tools that LR has that could help me do this? Thanks.
