How to get the best scan with phone or camera:
1. Fundo com contraste
Place the white sheet on a dark wooden table or tablecloth of another color so that the corners are visible.
2. Evite sombras diretas
Light the room from the side so that the shadow from your cell phone does not fall directly on the text in the document.
3. Use a Lupa de Ajuste
When dragging any of the 4 markers, the round magnifying glass in the corner shows the exact pixel of the corner of the paper.
