How to improve an image, if:

• the image is too dark and too soft
  Solution: Try to use brighter lighting. Otherwise, set a lower aperture value, i.e. open up the aperture.
• 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. If this does not help, try focusing the camera manually.
  If the image is only slightly blurred, try the Photo Correction tool that is available in the Image Editor. For more information, see the "Editing Images Manually" section.
• only part of the image is blurry
  Solution: Try setting a higher aperture value. Take pictures from a greater distance at maximum optical zoom. Focus on a point between the center and the edge of the image.
• flash causes glare
  Solution: Turn off the flash or try using other light sources and increasing the distance between the camera and the document.
