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. 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 the center of the image.

Enable the anti-shake feature, 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.

How to improve an image if:

The image is too dark or its contrast is too low.

Solution: Try using brighter lighting. If that is not an option, try setting a lower aperture

value.

The image is not sharp enough.

Solution: Autofocus may not work properly in poor lighting or when taking pictures from a

close distance. Try using brighter lighting. Use a tripod and self-timer to avoid moving the

camera when taking the picture.

If an image is only slightly blurry, the Photo Correction tool in the Image Editor of the OCR

Editor may help get better results. See also: If your document image has defects and OCR

accuracy is low .
