To obtain good quality photos of documents, be sure to position
the camera correctly and follow these simple recommendations.
Use a tripod whenever possible.
The lens should be positioned parallel to the page and look
towards the center of the document. The distance between the camera
and the document should be selected so that the entire page fits
within the frame when you zoom in. In most cases this distance will
be between 50 and 60 cm.
Even out the paper document or book pages (especially in the
case of thick books). The text lines should not be skewed by more
than 20 degrees, otherwise the text may not be converted
properly.
To get sharper images, focus on a part of the image between the
center of the document and one of its edges.
Enable the anti-shake system, as longer exposures in poor
lighting conditions may cause blur.
Use the automatic shutter release feature. This will prevent
the camera from moving when you press the shutter release button.
The use of automatic shutter release is recommended even if you use
a tripod.
