Photograph a document with your phone and get a clean, readable PDF.
A phone photo of a document is not a scan. It is dim, the paper looks grey, and the file is several megabytes of camera noise. Send it to an office and you will often be asked to send it again properly.
High-contrast mode fixes that: it pushes near-white paper to actual white and near-black ink to actual black, which is what a flatbed scanner does. The result reads cleanly, prints properly and is a fraction of the size. Greyscale is the gentler option when the page has photographs or a stamp you want to keep.
Shoot in even daylight if you can, keep the phone parallel to the page rather than at an angle, and fill the frame with the paper. Avoid a hard shadow across the page — high-contrast mode will turn a shadow into a grey band.
It converts each page to grey, then pushes light pixels to white and dark pixels to black with a smooth transition between. Paper texture and colour cast disappear and only the ink remains.
